Online Casino Terminology: Complete Glossary for Canadian Players (2026)

Casino platforms use specific terminology that is rarely explained before you need to understand it. A wagering requirement you misread, a bonus type you misunderstand, or a payment term you overlook can lead to frustration and wasted money. This glossary defines every term you are likely to encounter at a Canadian online casino, in plain language.

---

A

Active Bonus A bonus that is currently in play on your account, subject to wagering requirements that must be met before associated funds can be withdrawn.

Autoplay A slot machine feature that automatically spins the reels a set number of times without requiring you to press the spin button each time. Most Canadian casinos restrict autoplay when a bonus is active.

---

B

Bankroll The total amount of money you have set aside for gambling. Managing your bankroll — how much you bet per session relative to your total funds — is the foundation of responsible gambling practice.

Basic Strategy In blackjack, the mathematically optimal set of decisions (hit, stand, double down, split, or surrender) for every possible combination of your hand and the dealer’s upcard. Playing basic strategy reduces the house edge to approximately 0.5%.

Bonus Abuse Using casino bonuses in a way that violates the terms — such as creating multiple accounts to claim welcome offers repeatedly, or using excluded payment methods while claiming bonus eligibility. Casinos void winnings from bonus abuse and may close accounts.

Bonus Balance The portion of your casino account balance derived from bonus funds, as opposed to real money deposits. Bonus balance is usually subject to wagering requirements before it can be withdrawn.

Buy-In In poker and tournament contexts, the fee paid to enter a game or tournament. The buy-in establishes your starting chip stack.

---

C

Cashback Bonus A promotion that refunds a percentage of losses over a defined period — typically a week. A 10% cashback on weekly losses of $200 returns $20 to your account. Cashback is usually paid as cash rather than bonus funds, with no wagering requirement.

Cash Drop / Prize Drop A casino promotion where random prizes are awarded to players making qualifying bets during a defined period, independent of game outcomes. The prize can land on any eligible player at any time.

Comp Points / Loyalty Points Points earned on wagers at a casino, accumulated over time and redeemable for bonus funds, free spins, or cash. Part of most casino VIP or loyalty programs.

Contribution Rate The percentage of each bet that counts toward clearing a wagering requirement. Slots typically contribute 100%; table games often contribute 10–20% or 0% depending on the casino’s terms.

CVV The 3 or 4-digit security code on a credit or debit card. Required when entering card details at a casino cashier. The CVV is never stored by the casino after a transaction is processed at a compliant payment facility.

---

D

Dead Heat In sports betting, when two or more outcomes tie and winnings are divided among winners proportionally. Relevant context for Canadian players using sports betting features at casino-sportsbook platforms.

Deposit Bonus A bonus awarded when you make a qualifying deposit, typically expressed as a percentage of the deposit up to a maximum amount (e.g., 100% up to $500).

Double Down In blackjack, doubling your initial bet in exchange for committing to receive exactly one more card. Correct double-down situations (typically when your total is 10 or 11) are among the most player-advantageous moves available.

---

E

Edge Sorting An advantage play technique where a player exploits tiny manufacturing imperfections on card backs to identify face-down cards. Illegal in casinos and not possible in online casino environments using RNG-generated virtual cards.

Even Money A bet that pays 1:1 — you win exactly the amount you wagered. Even-money bets in roulette (red/black, odd/even, 1–18/19–36) are the lowest house edge bets in roulette.

Expected Value (EV) The statistical average return of a bet over many repetitions. A bet with positive EV (+EV) is one where you expect to profit on average. Casino games are designed with negative EV for the player. Maximising EV in a casino context means choosing the lowest house edge bets and games.

---

F

Free Spins Bonus spins on slot machines awarded without using your real money balance. Free spins usually apply to specific games designated by the casino, and any winnings are subject to wagering requirements before withdrawal.

Free Bet A bet placed using bonus funds rather than your own money. If the bet wins, you receive the winnings but not the original stake back.

Freeroll A tournament where the entry is free (no buy-in required). Common in online poker but also used by some casinos for slot tournaments.

---

G

Game Contribution Rate See Contribution Rate.

GGR (Gross Gaming Revenue) The casino’s total revenue from gambling: total bets minus total winnings paid out. Used to calculate operator taxes and as an industry metric. Not directly relevant to individual players but useful context.

---

H

Hard Hand In blackjack, a hand without an Ace, or with an Ace counted as 1 (because counting it as 11 would cause a bust). Example: Ace-6-10 = 17 hard (the Ace is counted as 1 to avoid a bust total of 27).

High Roller A player who places large bets, often qualifying for enhanced bonuses, dedicated account managers, higher withdrawal limits, and exclusive promotions. Casinos typically define the threshold for high-roller status by deposit or bet amounts.

Hold The percentage of wagered money the casino retains after paying out winnings. Equivalent to the house edge averaged across all players and sessions.

House Edge The casino’s mathematical advantage in any game, expressed as a percentage of each bet. A 2% house edge means the casino expects to keep $2 per $100 wagered over a large number of bets. See the Games With Best Odds guide for a full breakdown.

---

I

In-Play Betting Placing bets on a sporting event while it is in progress, with odds changing in real time. Available at casino-sportsbook hybrid platforms serving Canadian players.

---

J

Jackpot The largest prize available in a casino game. Fixed jackpots pay a set amount; progressive jackpots grow with each qualifying bet until won. The highest progressive jackpots in online casinos have paid over $20 million CAD equivalent.

Juice / Vig (Vigorish) The commission charged by a sportsbook on bets. In casino games, the equivalent is the house edge built into the game rules (such as the 5% commission on Banker wins in baccarat).

---

K

KYC (Know Your Customer) The identity verification process required by all licensed casinos before processing withdrawals. Typically requires a government ID, proof of address, and sometimes proof of payment method. See the Deposits and Withdrawals Guide for detailed KYC guidance.

---

L

La Partage A French roulette rule that returns half your stake on even-money bets when the ball lands on zero. Reduces the house edge on even-money bets from 2.70% (European) to 1.35% — the best roulette odds available.

Live Casino / Live Dealer Casino games hosted by human dealers in real-time, streamed via video. Players use digital interfaces to place bets on real cards, real wheels, and real dice. Evolution Gaming and Pragmatic Play Live are the two leading live casino providers in the Canadian market.

Loss Limit A player-set restriction on the maximum amount that can be lost within a defined period (daily, weekly, monthly). Available as a responsible gambling tool at all recommended Canadian casinos.

---

M

Match Bonus A deposit bonus that matches your deposit by a percentage. A 100% match bonus up to $500 means a $500 deposit receives $500 in bonus funds, giving you $1,000 to play with (subject to wagering requirements).

Max Bet The maximum bet allowed per spin or hand, either by the casino’s cashier limits or specifically restricted during active bonus play. Exceeding the max bet during a bonus can result in winnings being voided.

Maximum Win Cap A limit on the total amount withdrawable from winnings derived from a bonus, regardless of how much was won. For example, a max win cap of $500 on a free spins bonus means only $500 can be withdrawn even if you win $5,000.

MCC (Merchant Category Code) A four-digit code assigned to businesses that accept card payments, identifying their type. Online gambling transactions are MCC 7995, which many Canadian banks use to automatically block credit card deposits at casinos.

Multi-hand A casino game variant that deals multiple simultaneous hands, allowing you to play more positions at once. Available in blackjack (often up to 5 hands), video poker, and some other table game formats.

---

N

No-Deposit Bonus A bonus credited to your account without requiring a deposit. Typically free spins or a small cash amount. No-deposit bonuses have high wagering requirements and maximum win caps, but cost nothing to claim.

No-Wagering Bonus A bonus with no playthrough requirement — winnings from the bonus are available for immediate withdrawal. These are rare and highly valuable when available.

---

O

Odds The ratio of winning outcomes to losing outcomes for a bet, or the payout ratio on a winning bet. In craps, the “Odds” bet (capitalised) refers to the specific additional bet behind a Pass Line bet that pays at true mathematical odds with zero house edge.

---

P

Pay Line In slot machines, a line across the reels along which winning combinations are evaluated. Traditional slots have a single payline; modern video slots have 10, 20, or hundreds of paylines, or use the “ways to win” system where matching symbols on adjacent reels in any position count as a win.

Progressive Jackpot A jackpot that grows with a portion of every qualifying bet across all connected players. The jackpot increases until one player wins the entire pool, at which point it resets to a seed amount. The most well-known examples include Mega Moolah.

Provably Fair A cryptographic verification system used by Bitcoin casinos allowing players to mathematically verify that each game outcome was genuinely random and not altered by the casino. The player receives a hash of the server seed before each round and can verify the result afterward. Only available at crypto casinos.

---

R

RNG (Random Number Generator) The algorithm that determines the outcome of casino game events — card draws, reel spins, dice rolls. All online casino games that do not use real physical elements (i.e., not live dealer games) use a certified RNG.

RTP (Return to Player) The percentage of wagered money a game pays back to players over a statistically significant number of plays. A 96% RTP slot returns $96 for every $100 wagered on average. The inverse of RTP is the house edge: a 96% RTP game has a 4% house edge.

Reload Bonus A deposit bonus for existing players, offered on subsequent deposits after the welcome bonus has been claimed. Typically smaller than welcome offers (25–50% match) but subject to the same wagering requirement structure.

Responsible Gambling The practice of gambling within financial and time limits, with awareness of problem gambling risks and access to self-exclusion and support tools. See our Problem Gambling page for resources specific to Canadian players.

---

S

Self-Exclusion A formal mechanism allowing a player to voluntarily ban themselves from a casino or all casinos in a network for a defined period. In Ontario, the OLG’s MyPlayBreak program covers provincial sites. All AGCO-licensed casinos must offer self-exclusion tools. See our Problem Gambling page for province-specific self-exclusion options.

Soft Hand In blackjack, a hand containing an Ace counted as 11 without busting. A soft 17 (Ace + 6) is played differently from a hard 17 — basic strategy often calls for hitting or doubling on soft hands where you would stand on the hard equivalent.

Split In blackjack, dividing a pair of identically ranked cards into two separate hands, each with its own bet. Splitting Aces and 8s is almost always correct; splitting 10s or 5s is almost always wrong.

Stake The amount wagered on a single bet or spin.

---

T

Tournament A structured casino competition where players compete for a shared prize pool, typically by accumulating points, wins, or highest balances within a defined time. Slot tournaments are the most common format at Canadian online casinos.

Transaction ID (TxID) A unique identifier for a blockchain transaction. For Bitcoin casino withdrawals, the TxID allows players to track the status of their withdrawal on a public blockchain explorer.

---

V

Variance / Volatility The measure of how often and how much a game pays out. High-variance (high-volatility) slots pay out rarely but in large amounts when they do. Low-variance slots pay out frequently in smaller amounts. Neither is mathematically better — variance affects the character of the playing experience, not the long-run RTP.

VIP Program A loyalty structure at casinos offering escalating benefits to higher-volume players — enhanced cashback, higher withdrawal limits, dedicated account managers, faster processing, and exclusive events.

---

W

Wagering Requirement The total amount you must wager before bonus funds become withdrawable. Expressed as a multiplier: 30x on a $100 bonus means you must wager $3,000. See the

Welcome Bonus The promotional offer made to new players on their first deposit. Typically a match bonus plus free spins. The welcome bonus is the largest bonus most players will ever claim at a casino and is subject to the full terms described above.

Withdrawal Limit The maximum amount a casino will process in a single transaction, per day, per week, or per month. Check these limits in the cashier or terms before depositing at any casino, particularly if you are a higher-stakes player.

Frequently Asked Questions

What does “wagering requirements” mean in plain English? It is the total amount of bets you must place before the casino will let you withdraw bonus-derived winnings. A 30x wagering requirement on $100 means placing $3,000 in bets (on eligible games) before withdrawal is possible.

What is the difference between RTP and house edge? They describe the same thing from opposite directions. If a game has a 96% RTP, the house edge is 4%. RTP is what players get back; house edge is what the casino keeps.

What does “variance” mean in casino games? Variance (or volatility) describes how erratic a game’s payout pattern is. A high-variance slot may go many spins without paying, then deliver a large win. A low-variance slot pays smaller amounts more frequently. Neither is better or worse mathematically — they suit different playing styles.

What is the difference between a cash bonus and a bonus balance? Cash (real money) in your casino account can be withdrawn at any time, subject to KYC verification. Bonus balance must have wagering requirements completed before it converts to withdrawable cash.
