Betting Terms & Glossary
Some important terms for new players, with simple explanations.
RTP (Return to Player)
The theoretical percentage of total bets a game returns to players over the long run. A higher RTP means a relatively better chance of returns.
House Edge
The mathematical advantage the casino holds in every game. It is the inverse of RTP — worth considering when choosing a game.
Wager
To withdraw a bonus, you must place a set amount in bets — this is the wagering requirement. At 77db, you need to wager 15 times the bonus amount.
Stake
The amount of money you place on a single bet. A larger stake offers the chance of a larger reward, but the risk is also higher.
Odds
A numerical expression of the probability of an event. In betting, higher odds mean a bigger payout — but a lower chance of winning.
Parlay / Accumulator
Combining multiple bets together — if all of them are correct, the reward is big; if any one is wrong, you lose everything.
Live Bet
The ability to place bets in real time while a match or game is in progress. Odds change as the situation develops.
Cashout
The option to settle your bet before the match ends. Used to reduce risk or lock in a guaranteed profit.
Bankroll
The total funds set aside for gaming. Bankroll management is the foundation of responsible play.
Volatility
Describes the payout pattern of a slot game. High volatility means fewer but bigger wins; low volatility means smaller but more frequent wins.
Free Spin
A complimentary spin in a slot game given as a bonus. Usually earned through scatter symbols or special events.
Spread
In sports betting, the set point difference between two teams. Bets are placed based on this margin.
