Betting Terms and Glossary
Simple explanations of common betting and casino terms for new players.
RTP (Return to Player)
The average percentage of total bets that a game returns to players over the long term. The higher the RTP, the more player-friendly the game.
House Edge
The average long-term advantage the casino takes from each bet is called the house edge. It is the opposite of RTP — for example, 100% minus the RTP.
Wager / Wagering Requirement
The requirement specifying how many times a bonus must be wagered before it can be withdrawn. For example, a 10x wagering requirement means ৳10,000 in bets must be placed for a ৳1,000 bonus.
Odds
A numerical way of expressing the probability of an event occurring and the potential winnings. Decimal odds of 1.80 mean a ৳100 bet returns ৳80 in profit.
Parlay / Accumulator
Combining multiple bets together, where the full payout is only received if every outcome is correct. The risk is higher, but so is the potential payout.
Live Bet
Placing a bet in real time while a match or game is in progress. Odds change after every ball in cricket, so placing a bet at the right moment is very important.
Cashout
The ability to exit a bet before the match ends. This option is used to secure a partial profit or avoid a big loss.
Volatility
A measure of how often and how large the rewards are in a slot game. High volatility means fewer wins but the chance of larger rewards.
Bankroll
The total amount of money set aside for betting. Proper bankroll management is the key to healthy and responsible play over the long term.
