46 gambling, casino and scam terms in plain English: RTP, house edge, KYC, junket, money mule, wagering and more. Each links to the full explainer.

A

Affiliate
A website or creator paid a commission by an operator for sending new players. HotStakes is an affiliate directory: we may earn a commission when you sign up through our links, at no cost to you.
AML (anti-money laundering)
The rules and checks that stop criminal money being cleaned through a business. Licensed casinos must monitor accounts, verify identity and report suspicious activity. Read the explainer →

B

Baccarat
A card game where you bet on Player, Banker or Tie. Banker has the lowest house edge (about 1.06% with the usual 5% commission); Tie has the highest. Read the explainer →
Banker commission
The fee (usually 5%) taken from winning Banker bets in baccarat. It exists because Banker wins slightly more often than Player. Read the explainer →
Bonus buy
A slot feature that lets you pay a fixed price, often 50–100× your bet, to go straight to the bonus round instead of waiting to trigger it.

C

Cashback
A bonus that returns a percentage of your net losses over a period. It reduces losses but does not change the house edge of the games you play.
Concessionaire
One of the six companies licensed by the Macau government to run casinos: Sands China, Galaxy, MGM China, Melco, SJM and Wynn Macau. Read the explainer →
Curaçao Gaming Authority (CGA)
The regulator created by Curaçao's National Ordinance on Games of Chance (LOK). It replaced the old master-licence and sub-licence system with direct licences. Read the explainer →

D

Demo mode
Free play with virtual credits. The maths are the same as the real-money game, but nothing is won or lost. Every slot on HotStakes has a free demo. See games →
DICJ
Macau's Gaming Inspection and Coordination Bureau, the regulator that licenses casinos and gaming promoters and publishes gaming revenue data. Read the explainer →
Dragon Tiger
A fast two-card live game: one card to Dragon, one to Tiger, highest wins. Ties usually cost half of a Dragon or Tiger bet. See games →

E

Expected value (EV)
The average result of a bet if you could repeat it forever. On casino games the expected value is negative: stake × house edge is the average cost. Try the tool →

G

Gambler's fallacy
The false belief that a result is "due" because it has not happened for a while. Each spin or hand is independent; past results do not change the odds.
Game contribution
How much of each bet counts towards a wagering requirement. Slots often count 100%; table and live games often count 10–20% or nothing. Try the tool →
Gaming promoter
The legal name for a junket in Macau. Since 1 January 2023 a promoter may work with only one concessionaire and is paid a commission. Read the explainer →
GGR (gross gaming revenue)
What players lose to the operator: total bets minus winnings paid out, before costs and tax. Regulators tax and report GGR.

H

Hit frequency
How often a slot spin returns any win at all. A high hit frequency does not mean profit: many "wins" pay back less than the bet. Read the explainer →
House edge
The casino's built-in average profit on each bet, as a percentage of the stake. It is 100% minus the RTP: a 97% RTP game has a 3% house edge. Read the explainer →

J

Junket
A middleman that brought high rollers to casinos, often lending them money and running private VIP rooms. Macau tightened the rules from 2023. Read the explainer →

K

KYC (know your customer)
Identity checks a licensed operator must run: ID, proof of address and sometimes source of funds. Strong regulators expect them before you play, not only at withdrawal. Read the explainer →

L

Live dealer
Table games streamed from a studio with a real dealer, such as baccarat, roulette and Dragon Tiger. Bets are placed on screen. See games →

M

Malta Gaming Authority (MGA)
Malta's gambling regulator, one of the most widely used licences in online gambling. Its public register lets you check a licence. Read the explainer →
Max bet rule
A bonus term capping how much you can stake per spin or hand while a bonus is active. Breaking it is a common reason winnings get voided. Read the explainer →
Max win
The largest payout a slot can give on one spin, usually shown as a multiple of the bet, such as 5,000×. Read the explainer →
Money mule
Someone who lets criminals move money through their bank account. In Malaysia giving others control of your account is an offence with up to 7 years' jail. Read the explainer →

P

PAGCOR
The Philippine Amusement and Gaming Corporation, the state-owned regulator and operator of casinos in the Philippines. Read the explainer →
Pig-butchering scam
A long-con fraud (shā zhū pán) where a stranger builds trust over weeks, then steers the victim into a fake investment or betting platform. Read the explainer →
POGO
Philippine Offshore Gaming Operator: firms licensed in the Philippines to serve gamblers abroad. The Philippines banned them in 2024. Read the explainer →
Proxy betting
Placing bets in a casino on behalf of someone who is not there, often relayed by phone or video. It is illegal in Macau. Read the explainer →

R

Recovery scam
A second scam aimed at fraud victims: someone promises to get lost money back for an upfront fee. Real police and banks do not charge to recover funds.
Responsible gambling
Tools and habits that keep gambling within limits: deposit limits, time-outs, self-exclusion and only playing with money you can afford to lose. Read the explainer →
RNG (random number generator)
The software that decides each slot or digital table result. In licensed games it is tested by independent labs so outcomes cannot be predicted.
Rolling chip
Non-negotiable chips used in VIP gambling. Junkets were paid on "rolling", the total value of chips bet, not on what players lost. Read the explainer →
RTP (return to player)
The share of all money staked that a game pays back over millions of rounds. A 96% RTP slot keeps 4% on average; it says nothing about one session. Read the explainer →

S

Scam compound
A guarded site, often in Myanmar, Cambodia or Laos, where trafficked workers are forced to run online fraud such as pig-butchering scams. Read the explainer →
Self-exclusion
Asking an operator, or a national scheme, to block you from gambling for a set period. Licensed operators must honour it.
Source of funds
Proof of where the money you gamble comes from, such as payslips or bank statements. Operators ask for it under anti-money-laundering rules. Read the explainer →
Sticky bonus
A bonus that can be played with but never withdrawn; only winnings above the bonus amount can be cashed out. Read the explainer →

U

UK Gambling Commission (UKGC)
Great Britain's gambling regulator. It publishes licensing rules, enforcement actions and a public licence register. Read the explainer →
Under-the-table betting
Private bets placed alongside a recorded casino bet, settled off the books. Courts in Macau treated it as illegal gambling that cut tax. Read the explainer →
Unlicensed casino
A gambling site with no valid licence, or a fake one. Players have no regulator to complain to and withdrawals can be refused at will. Read the explainer →

V

VIP room
A private high-limit gaming area. In Macau many were run by junkets until the 2023 law ended revenue-sharing arrangements. Read the explainer →
Volatility
How spread out a slot's results are. High volatility: rare, large wins and long dry spells. Low volatility: frequent small wins. Read the explainer →

W

How many times you must bet a bonus (or bonus plus deposit) before you can withdraw. 35× on a RM100 bonus means RM3,500 of bets. Read the explainer →
