Casino Glossary

A complete reference of online casino terminology. From RTP and wagering requirements to KYC and self-exclusion, understand every term before you play.

A slot feature that spins the reels automatically for a set number of rounds without manual input. Most regulators now require loss limits and session caps on autoplay.

Bankroll
The total amount of money a player has set aside specifically for gambling. Effective bankroll management means never wagering more than you can afford to lose.

A card game where the goal is to beat the dealer by getting a hand value as close to 21 as possible without going over. House edge ranges from 0.5% to 2% depending on rules.
Bonus Abuse
Exploiting promotional offers in ways not intended by the casino. Most operators have anti-abuse clauses that can void winnings and close accounts.
Bonus Round
A special feature triggered during gameplay that offers extra winning opportunities, such as free spins, pick-and-click games, or multiplier trails.
C
2 terms
Cashback
A percentage of net losses returned to the player, typically ranging from 5% to 20%. Cashback may come with lower wagering requirements than deposit bonuses.

H
2 terms

Responsible Gambling
The practice of gambling within your means using tools like deposit limits, loss limits, session timers, and self-exclusion. Every licensed casino must offer these tools.
