Betting Terms / Glossary
Simple explanations of common betting and casino terms for new players.
RTP (Return to Player)
The theoretical percentage of total wagers that a game returns to players over the long run. The higher the RTP, the more generous the game is in theory.
House Edge
The casino's mathematical advantage — the percentage the casino retains on average from each bet over the long run.
Wager / Stake
The amount of money placed on a single bet. A wagering requirement is the number of times you must bet before withdrawing a bonus.
Odds
A way of expressing the probability of an event occurring. In betting, higher odds mean a larger potential payout but a lower probability of winning.
Parlay / Accumulator
Combining multiple bets into one where every outcome must be correct to receive the full payout. Higher risk, bigger reward.
Live Bet
Placing a bet in real time while a game is in progress. It gives you the opportunity to read how the match is going and bet at the right moment.
Cashout
The option to withdraw a set amount before the outcome of a bet is decided — it reduces risk by securing a partial return.
Bankroll
The total amount of money set aside specifically for betting or gaming. Proper bankroll management helps you enjoy playing over the long term.
Volatility
Describes the payout pattern of a slot game — high volatility means larger prizes but less frequent wins; low volatility means smaller but more frequent wins.
Free Spin
Complimentary spins received as a bonus that allow you to play a slot game without using your own money.
Android App
