Online Slots Australia: A Data-Led Guide to the 2026 Market
Online slots in Australia occupy an unusual position. The domestic regulatory framework restricts real-money online casino play, yet Australian adults spent an estimated AU$25 billion on pokies across all channels in the most recent full year of published data, and the online slice of that figure keeps expanding. This guide treats the market as a subject of study: which operators serve Australian players, what they pay, how fast withdrawals land, and where the friction points sit.
No hype. No promises of untold riches. What follows is a walkthrough built around a single hypothetical player, a 34-year-old from Newcastle we will call Dan, whose journey from first search to first cash-out mirrors what thousands of Australians do each month. Along the way you get the numbers, the operator list, the payment rails and the legal picture as it stands in 2026.
One point of housekeeping before the data begins. The brands named here mostly operate under offshore licences — Curaçao, Anjouan, Kahnawake — rather than under a state or territory Australian licence. That is a factual description, not a warning label. Australian players can and do access them; the compliance burden sits with the operator, and the legal position for the player is nuanced. We unpack that in full below.
The Australian Online Slots Market in Numbers
Australia has roughly 20.5 million adults and one of the highest per-capita gambling participation rates on earth. Published industry tracking puts pokies-style play — land-based and online combined — at the centre of that activity, with slot titles accounting for somewhere between 75% and 80% of all casino-game wagering by value. The online segment is smaller than the land-based one but growing faster, and it skews younger.
Demographic splits matter for anyone choosing an operator. Players aged 25 to 44 make up the largest share of online slot accounts, while the 55-plus cohort still dominates club and pub pokies. That gap explains why offshore sites lean hard into mobile-first design, PayID deposits and fast crypto rails: their core audience expects a deposit to clear before the kettle boils.
Spend per active online player is harder to pin down because operators do not publish it. What is observable is the average deposit size, which industry surveys place in the AU$40 to AU$90 band for casual players, with a long tail of high-rollers well above that. Dan, our Newcastle player, starts with AU$50 and a firm rule that he will not top up more than twice in a week.
How big is the Australian online pokies market?
Exact online-only figures are not publicly reported, but total Australian gambling expenditure sits near AU$25 billion annually across all verticals, and pokies represent the single largest share. Online casino-style play is estimated in the low single-digit billions and rising year on year, constrained by payment-blocking rules rather than by demand.
Which age groups play online slots most?
The 25 to 44 bracket leads online slot participation, according to successive national gambling surveys. Players under 25 are the fastest-growing segment by account creation but the smallest by total spend. The 45 to 64 group is the most stable and highest-value cohort per account, which is why retention offers target them specifically.
How Australian Players Actually Access Online Slots
Dan's first move is a search. His second is a bank transfer, and that is where the Australian story gets interesting. The Interactive Gambling Act 2001 prohibits operators from offering real-money casino games to Australians without an Australian licence, and no online casino holds one. The Act regulates the operator, not the player. No Australian has ever been prosecuted for placing a bet on an offshore slots site.
Payment rails tell the real story. Major banks and the big card schemes have been directed to block transactions to unlicensed gambling merchants, which is why the market shifted toward PayID, POLi, Neosurf vouchers and cryptocurrency. PayID in particular has become the default because it settles in under a minute and runs through the New Payments Platform, which sits outside the card-blocking architecture.
The result is a two-tier access model. Card deposits fail often enough that most operators no longer lead with them. E-wallets and vouchers work reliably. Crypto works everywhere and settles fastest, though it introduces volatility and a tax-record keeping headache that casual players rarely consider until July.
Is it legal for Australians to play online slots?
Playing is not an offence under Commonwealth law; offering unlicensed online casino games to Australians is. The Interactive Gambling Act targets operators, and enforcement falls to the Australian Communications and Media Authority, which has blocked hundreds of domains since 2017. Players face no legal penalty for signing up to an offshore site.
Why do card deposits get declined at offshore casinos?
Australian banks and card issuers apply merchant-category blocks to unlicensed gambling transactions under pressure from regulators. The decline is automatic and often invisible to the player. PayID, bank transfer, Neosurf and crypto bypass the card network entirely, which is why they dominate deposit methods on Australian-facing sites.
Top Online Slot Operators Serving Australian Players
Dan ends up comparing six or seven sites before settling. The list below reflects the operators most commonly used by Australian players in 2026, ranked loosely by a blend of game library size, withdrawal speed, bonus terms and payment flexibility. None holds an Australian licence; all operate offshore. Treat the rankings as a starting comparison, not an endorsement.
| Operator | Standout Feature | Typical Withdrawal Time | Min Deposit |
|---|---|---|---|
| Rocket Casino | Large pokies library, frequent reloads | 1–24 hours (crypto), 1–3 days (bank) | AU$20 |
| National Casino | Broad provider mix, PayID support | 1–2 days | AU$20 |
| Winspirit Casino | Crypto-first, fast cashouts | Under 1 hour (crypto) | AU$15 |
| Ignition Casino | Poker plus slots, established brand | 1–2 days | AU$20 |
| Bitstarz Casino | Provably fair titles, wide crypto support | 10–60 minutes | AU$20 |
| King Billy Casino | Deep bonus ladder, 4-tier welcome | 1–3 days | AU$20 |
| Playamo Casino | Thousands of titles, PayID friendly | 1–2 days | AU$20 |
| Hellspin Casino | Modern interface, strong mobile play | 1–2 days | AU$20 |
| Fairgo Casino | Long-standing Aussie-facing brand | 1–3 days | AU$20 |
| Joe Fortune Casino | Simple layout, pokies focus | 1–2 days | AU$20 |
Beyond the ten above, the Australian-facing pool includes Richard Casino, Ripper Casino, Bizzo Casino, Ozwin Casino, Casino Mate, Vegastars Casino, Just Casino, SkyCrown Casino, Royal Reels Casino, Clubhouse Casino, Leon Casino, Neospin Casino, Woo Casino, Intensity Casino, Fastpay Casino, Pocket Pokies, Rollxo Casino, BSB007 Casino, Mega Medusa Casino, Wolf Winner Casino, Zoome Casino, Stay Casino, Surge Casino, Lucky Green Casino, Ricky Casino, Golden Crown Casino, 21Bit Casino, Croco Casino, LevelUp Casino, Dolly Casino, VegasNow Casino, 7Bit Casino, Stellar Spins Casino, Razed Casino, Uptown Pokies Casino, Betzillo Casino, Winshark Casino, Spirit Casino, Casino World, Lukki Casino, Kingmaker Casino, Jeetcity Casino, Lucky Dreams Casino, Pokiesurf Casino, House of Pokies, Spinsy Casino, Deespin Casino, Wild Fortune Casino, King Johnnie Casino, SpeedAU Casino, Axe Casino, Avantgarde Casino, Jackpot Jill Casino, Rich Casino, Stake Casino, Playfina Casino, Malina Casino, Goospin Casino, PlayCroco Casino, Johnny Kash Casino, CrownPlay Casino, Roo Casino, Lucky Ones Casino, 28 Mars Casino, Yabby Casino, Gamdom Casino, Jet4Bet Casino, Spin Samurai Casino, Mafia Casino, Instant Casino, True Fortune Casino, Cocoa Casino, Boomerang Casino, Goldex Casino, Jokaroom Casino, Spinago Casino, Cleobetra Casino, Lucky Elf Casino, Roospin Casino, Rooli Casino, Oshi Casino, Waboom77 Casino, Casiny Casino, Spinit Casino, Fortunica Casino, Boho Casino, Nine Casino, Rainbet Casino, Lets Lucky Casino, Pure Casino, Wild Tokyo Casino, House of Jack Casino, M99 Casino, 9AU Casino, Paradise 8 Casino, Moonwin Casino, Bet365 Casino, Limitless Casino, Asino Casino, N1Bet Casino, Red Stag Casino, Lucky Wins Casino, VegasStars Casino, Syndicate Casino, Wazamba Casino, TrueBlue Casino, TCL99 Casino, Realz Casino, Winmate88 Casino, Gday77 Casino, UFO9 Casino, RetroBet Casino, Abigcandy Casino, Lucky Hunter Casino, Shazam Casino, ReefSpins Casino, Roobet Casino, AmunRa Casino, Spinfred Casino, Vegas Hero Casino, Aussie Play Casino, Pistolo Casino, SlotLounge Casino, Reels Grande Casino, Candyland Casino, Fafabet9 Casino, Legit99 Casino, Wildcard City Casino, Crowngold Casino, Roby Casino, United Casino, Fatbet Casino, Casino4U, Voodoo Casino, SpinsUp Casino, This Is Vegas Casino, Wanted Win Casino, Victor96 Casino, Katsubet Casino, GoldWin Casino, Velvet Spins Casino, HeapsOWins Casino, Goldbet Casino, Buran Casino, Bitkingz Casino, IPay9 Casino, Crown Sydney Casino, Space9 Casino, Wild Tornado Casino, UnitedAU Casino, West28 Casino and BetOnRed Casino.
That is a long list, and most of it is noise for any single player. The practical filter is narrower: does the site accept PayID or crypto, how fast does it pay, and what wagering requirement sits on the welcome bonus. Dan's shortlist comes down to three because two of his first picks wanted 40x wagering on a bonus that expired in seven days.
Which online casino is best for Australian slots players?
There is no single best, but Bitstarz and Winspirit lead on withdrawal speed for crypto users, while Playamo and Rocket Casino offer the widest pokies libraries. Fairgo and Joe Fortune have the longest track record with Australian players. Match the operator to your payment method first, then compare bonuses.
Do these operators hold Australian licences?
None of them does. Every brand listed operates under an offshore licence, most commonly Curaçao, Anjouan or Kahnawake. That means Australian consumer protections and local dispute-resolution bodies do not apply. Players rely on the operator's own terms, its licensing jurisdiction and, in practice, its reputation.
Game Providers and Slot Libraries
Dan cares less about the total game count than about whether the titles he likes are there. Provider mix is the real differentiator. Pragmatic Play's Gates of Olympus and Sweet Bonanza family dominates Australian play by volume, with NetEnt's Starburst and Gonzo's Quest still pulling steady traffic more than a decade after release. Microgaming's Mega Moolah progressive remains the reference point for jackpot hunters.
Newer studios have carved out space. Hacksaw Gaming's volatility-forward design appeals to players chasing large multipliers, while Nolimit City and Push Gaming target the same high-variance audience. Evolution dominates live-dealer slots and game-show hybrids such as Crazy Time. A site carrying Pragmatic, NetEnt, Microgaming, Hacksaw, Play'n GO and Evolution covers roughly 80% of what Australian players actually spin.
Library size ranges widely. Smaller sites carry 500 to 1,000 titles; the largest, including Playamo and Rocket Casino, advertise several thousand. That number is inflated by demo-only or region-restricted games, so check that a specific title loads before depositing. Dan learned this the hard way when a site advertised 4,000 games but blocked 300 of them for Australian IPs.
| Provider | Signature Titles | Typical Volatility | Max Win (x stake) |
|---|---|---|---|
| Pragmatic Play | Gates of Olympus, Sweet Bonanza, Sugar Rush | Medium to high | 5,000x |
| NetEnt | Starburst, Gonzo's Quest, Dead or Alive 2 | Low to high | 111,000x (Dead or Alive 2) |
| Microgaming | Mega Moolah, Immortal Romance, Thunderstruck II | Low to medium | Progressive (millions) |
| Hacksaw Gaming | Wanted Dead or a Wild, Le Bandit | Very high | 12,500x |
| Play'n GO | Book of Dead, Reactoonz | Medium to high | 5,000x |
| Evolution | Crazy Time, Lightning Roulette | Varies (live) | Up to 25,000x |
What is the most popular online slot in Australia?
By play volume, Pragmatic Play's Gates of Olympus and Sweet Bonanza consistently rank at the top with Australian players, alongside NetEnt's Starburst. The popularity reflects a mix of high maximum wins, frequent bonus triggers and heavy promotion across operator lobbies rather than any objective superiority.
What does RTP mean and why does it matter?
Return to player is the percentage of all wagered money a slot pays back over millions of spins. A 96% RTP game returns AU$96 for every AU$100 staked in the long run. A 2% difference between a 94% and 96% title compounds sharply over thousands of spins, so check the figure before you play.
Bonuses, Wagering and the Real Cost of a Welcome Offer
The welcome bonus is where most players lose value without noticing. A headline "100% up to AU$1,000 plus 200 free spins" sounds generous until you read the terms. Wagering requirements of 30x to 40x on the bonus, plus a 7-day expiry and a AU$5 maximum bet while the bonus is active, turn a large offer into a grind that most players never clear.
Dan does the arithmetic on a AU$200 deposit with a 100% match and 35x wagering. The bonus is AU$200, so he must wager AU$7,000 before withdrawing anything from it. At AU$1 per spin that is 7,000 spins. At 96% RTP, expected loss across those spins is roughly AU$280. The bonus is worth less than the expected cost of clearing it.
Free spins carry their own traps. Winnings from spins are usually credited as bonus funds subject to the same wagering, and many offers cap the maximum cashout from free-spin winnings at AU$100 to AU$200. Reload bonuses, cashback and loyalty points follow similar patterns. The only reliable comparison is effective value: bonus size divided by total wagering, then adjusted for game contribution rates.
How do wagering requirements work on slot bonuses?
Wagering is the multiple of the bonus (sometimes bonus plus deposit) you must bet before withdrawing winnings. A 35x requirement on a AU$100 bonus means AU$3,500 in total bets. Slots usually contribute 100% toward wagering, while table games and live dealer titles often contribute 10% or less.
Are no-deposit bonuses worth claiming?
They cost nothing, so the downside is limited to the time spent. The catch is that no-deposit offers typically carry maximum cashout caps of AU$50 to AU$100 and wagering of 40x or more. Treat them as a free trial of the platform rather than a realistic route to profit.
Payments: Deposits, Withdrawals and the PayID Shift
Payment method determines the entire experience. Dan's first deposit attempt with a debit card fails, which is now the norm rather than the exception. His second, via PayID, clears in about 40 seconds. That single shift explains why PayID pokies have become the dominant search behaviour among Australian players.
Withdrawal speed varies enormously. Crypto withdrawals at Bitstarz and Winspirit often land in under an hour. Bank transfers and PayID cashouts typically take 1 to 3 business days, longer if the operator runs manual review on first withdrawals. Many sites impose a pending period of 24 to 48 hours during which you can reverse the request, which is convenient for the operator and costly for the impulsive player.
Fees are mostly absorbed by the operator, though some charge on small withdrawals or apply a minimum cashout of AU$20 to AU$50. Cryptocurrency withdrawals avoid fees at the casino end but incur network fees and conversion spreads. Dan's AU$50 deposit becomes roughly AU$48 after crypto conversion, a detail worth knowing before you assume crypto is free.
How fast are PayID withdrawals at Australian online casinos?
Most operators process PayID withdrawals within 1 to 3 business days, with the pending period accounting for much of the delay. A handful advertise same-day processing for verified accounts. First withdrawals take longer because identity verification is completed before release.
What is the minimum deposit at most sites?
The standard minimum deposit across Australian-facing operators sits at AU$20, with some crypto-first sites accepting AU$10 to AU$15. Free-spin and no-deposit offers bypass the threshold entirely. Check the minimum before claiming a match bonus, because a AU$10 deposit on a 100% offer yields only AU$10 in bonus funds.
Licensing, Regulation and the Legal Position in 2026
The regulatory picture is stable but not simple. The Interactive Gambling Act 2001 prohibits unlicensed operators from offering real-money online casino games to Australians. The ACMA enforces this through domain blocking and has blocked well over 1,000 gambling-related sites since 2017. None of that changes the player's legal position, which remains unaffected.
State and territory regulators govern land-based pokies, and several states run their own self-exclusion schemes. The national framework is coordinated through the Department of Social Services, which maintains the Gambling Help Online service. The minimum legal age for gambling in Australia is 18 in every state and territory except where specific lottery products allow younger participation.
Offshore operators sit outside this framework entirely. Their licences come from Curaçao, Anjouan or Kahnawake, each with different dispute-resolution mechanisms. If a payout is refused, the player's recourse is the operator's complaints process, then the licensing authority. That is thin compared with an Australian licence, but it is the reality of the market and worth understanding before depositing.
What happens if an offshore casino refuses to pay?
Recourse runs through the operator's internal complaints process first, then to its licensing authority — Curaçao's Gaming Control Board, Anjouan's regulator or Kahnawake's Gaming Commission. Outcomes vary. Document every transaction and keep screenshots of terms; evidence is the only leverage a player holds.
Does the ACMA block Australian players from accessing these sites?
The ACMA blocks domains at the ISP level, but blocks are inconsistent and easily circumvented. New domains appear regularly. The blocks target operators, not players, and no Australian has faced penalties for using an offshore site. The practical effect is disruption rather than prevention.
A Player's Journey: From First Search to First Cash-Out
Dan's week unfolds in a predictable sequence, and it is worth tracing because the friction points are the same for nearly every Australian player. Day one: he searches, compares three sites, reads the terms on two and abandons one because the wagering is 45x. He registers at a second site, verifies his email and downloads nothing because the site is mobile-first.
Day two: his card deposit fails. He switches to PayID, deposits AU$50 and claims a 100% match with 30x wagering. He plays Pragmatic titles at AU$0.50 to AU$1 per spin for about 90 minutes. He is up AU$30 at one point, down AU$20 at another, and closes the session roughly even. The bonus remains locked behind AU$3,000 in wagering.
Day four: he requests a AU$150 withdrawal after a decent run. The site asks for ID verification — a driver's licence and a utility bill. He submits both. The withdrawal sits pending for 36 hours, then clears via PayID on day six. Total elapsed time from first deposit to first cash-out: five days. That is a typical Australian experience, not a fast one.
How long does identity verification take?
Verification usually completes within 1 to 24 hours once documents are submitted. Delays occur when the name on the account does not match the ID, the document is blurry, or the address is outside the operator's accepted regions. Submit documents before your first withdrawal to avoid the pending-period overlap.
Can you withdraw a bonus immediately?
No. Bonus funds remain locked until wagering is complete, and any withdrawal before that forfeits the bonus and its associated winnings. Some operators allow you to cancel the bonus and withdraw your original deposit, minus any winnings generated from bonus play. Read the terms before opting in.
Slot Mechanics: Volatility, RTP and What the Numbers Actually Mean
Slot design runs on three dials: RTP, volatility and maximum win. RTP is the long-run payback percentage. Volatility describes how wins are distributed — low volatility pays small amounts often, high volatility pays rarely but larger. Maximum win caps the top payout, usually expressed as a multiple of stake. A game with a 96% RTP, high volatility and a 5,000x max win behaves very differently from a 96% RTP, low-volatility title with a 500x cap.
Dan prefers medium volatility because his sessions are short. A high-volatility Hacksaw title can swallow 200 spins without a meaningful return, which is fine if you have the bankroll and patience, punishing if you do not. The maths is unforgiving: at 96% RTP, expected loss per AU$100 wagered is AU$4, and that figure holds regardless of volatility.
Feature buy options change the calculation. Buying free spins at 100x stake converts a volatile base game into a fixed-cost gamble on the bonus round. Pragmatic's Sweet Bonanza buy costs 100x stake; the expected return on that purchase still sits at the game's RTP, but the variance is concentrated into a single spin sequence. It is a faster route to the same long-run outcome.
Is a higher RTP slot always better?
For long-run expected value, yes. A 97% RTP game loses AU$3 per AU$100 wagered; a 94% game loses AU$6. Over 10,000 spins at AU$1, that is a AU$300 difference. Volatility affects the journey, but RTP determines the destination.
What is a realistic bankroll for online slots?
Set a bankroll you can lose without consequence, then size bets at 1% to 2% of it. A AU$500 bankroll supports bets of AU$5 to AU$10 per spin across a session of a few hundred spins. Betting AU$5 on a AU$50 bankroll is a 10-spin session, not a session at all.
Mobile Play and the Australian Connection Quality Picture
Australian mobile infrastructure shapes how slots are played. 5G coverage now reaches most of the population, but regional players still deal with variable latency. Slot titles are lightweight compared with live dealer streams, so most games run fine on 4G. Live dealer games are the exception; they need a stable connection and consume far more data.
Dan plays on an Android phone during his commute. Pragmatic and NetEnt titles load in under 5 seconds on 4G. The live-dealer lobby buffers twice in a 20-minute session. That pattern is common: slots are mobile-friendly, live games are not reliably so outside metro areas. If live dealer play matters to you, test the connection before depositing.
App availability is limited. Most offshore operators do not offer native iOS or Android apps because app stores restrict gambling software. The workaround is a mobile-optimised browser site, which is what nearly all Australian players use. Progressive web app installs are offered by a few operators, but the experience is close to identical to the browser version.
Do Australian online casinos have mobile apps?
Rarely. Apple's App Store and Google Play restrict real-money gambling apps in most regions, so offshore operators rely on mobile-optimised websites. These load quickly and support the full game library. A few sites offer installable web apps, but functionality matches the browser version.
How much data does an online slot use?
A standard slot session uses roughly 5MB to 20MB per hour, depending on graphics and animation. Live dealer games consume far more, often 200MB to 500MB per hour. On a mobile plan, slots are cheap; live dealer sessions are not.
Responsible Gambling and Player Protections
The legal gambling age in Australia is 18 across every state and territory. If gambling stops being a form of entertainment and starts feeling compulsory, help is available around the clock. Gambling Help Online operates a free 24/7 service, and the national helpline number is 1800 858 858. Both connect callers to trained counsellors at no cost.
Self-exclusion is the strongest tool available. Every Australian state and territory operates a self-exclusion register for land-based venues, and players can exclude from pubs, clubs and casinos in their state for periods ranging from 6 months to 5 years. For online play, the BetStop national self-exclusion register, launched in August 2023, covers licensed Australian wagering providers. It does not cover offshore casino sites, which is a limitation worth understanding.
Practical protections for online slot players include deposit limits set at the operator level, session timers, loss limits and the use of separate bank accounts for gambling. Dan sets a AU$200 weekly deposit limit on day one and sticks to it. That single measure does more to protect a bankroll than any bonus term ever will.
What is the gambling helpline number in Australia?
The national gambling helpline is 1800 858 858, available 24 hours a day, 7 days a week, free of charge. Gambling Help Online also offers web chat and email support. Both services connect callers with trained counsellors and can refer to local face-to-face support.
How does the BetStop register work?
BetStop is the national self-exclusion register for licensed Australian wagering providers, launched in August 2023. Registration is free and can last from 3 months to permanently. It blocks sign-ups and betting accounts with participating operators. Offshore casino sites fall outside its scope, so pair it with operator-level limits.
Common Questions Australian Players Ask
Can Australians legally play online slots?
The Interactive Gambling Act 2001 makes it an offence for unlicensed operators to offer online casino games to Australians, but it does not criminalise the player. No Australian has been prosecuted for playing at an offshore site. The legal risk sits with the operator, not the individual placing the bet.
What is the best payment method for Australian online slots?
PayID is the most practical for most players because it settles in under a minute and bypasses card blocks. Cryptocurrency is faster for withdrawals but introduces conversion costs and record-keeping. Neosurf vouchers suit players who prefer not to link a bank account at all.
How much can you win on online slots in Australia?
Maximum wins depend on the game. Pragmatic titles typically cap at 5,000x stake, Hacksaw games at 12,500x, and NetEnt's Dead or Alive 2 at 111,000x. Progressive jackpots such as Microgaming's Mega Moolah have paid out in the millions. Winnings are subject to the operator's terms and any bonus wagering.
Do you pay tax on online slots winnings in Australia?
Australia does not tax gambling winnings for recreational players, and the ATO treats them as windfalls rather than income. Professional gamblers may be assessed differently. Winnings held in cryptocurrency can trigger capital gains tax obligations when converted, which is a separate consideration.
Why do Australian banks block casino deposits?
Banks and card issuers apply merchant-category blocks to unlicensed gambling transactions under regulatory pressure. The blocks target the merchant, not the customer, and are applied automatically. PayID, bank transfer, Neosurf and crypto bypass the card network, which is why operators promote them heavily.
Are online slots rigged?
Licensed operators use random number generators audited by independent testing labs such as eCOGRA and iTech Labs. Provably fair titles on crypto sites allow players to verify outcomes cryptographically. Unaudited sites exist, which is one reason to check whether an operator publishes its RTP figures and testing certificates.
What is the average RTP of online slots?
Most modern slots sit between 94% and 97%, with 96% the common benchmark. Pragmatic and NetEnt titles cluster around 96%, while some high-volatility Hacksaw games run lower on certain bet modes. Always check the in-game paytable, because RTP can vary between bet levels on the same title.
The Australian online slots market in 2026 is best understood as a mature grey-zone ecosystem: offshore operators, domestic payment friction, a player base that has adapted around both, and a regulatory framework that constrains supply without touching demand. Dan's five-day journey from search to cash-out captures the pattern. The numbers, the payment rails and the licensing reality are all knowable, and knowing them is the difference between a controlled session and an expensive lesson.
