Betting Terminology
For new players — simple explanations of common betting and casino terms.
RTP (Return to Player)
The theoretical rate at which a game returns a percentage of total bets to players over the long run. For example, an RTP of 96% means an average of ৳96 is returned for every ৳100 wagered.
House Edge
The casino's mathematical advantage — representing the average percentage the casino retains on every bet.
Wager
The amount of money you place on a specific bet. In the context of bonuses, a wagering requirement means how many times you must bet the bonus before you can withdraw it.
Odds
A numerical expression of the probability of an outcome. Higher odds mean lower probability but a greater reward.
Parlay / Accumulator
Combining multiple bets into one larger bet. If all outcomes are correct, the reward multiplies significantly.
Live Bet
Placing a bet in real time while a match or event is in progress. Odds change continuously and add extra excitement.
Cashout
The option to withdraw partial or full winnings before the outcome of a bet is decided.
Bankroll
Your total gaming budget — the total amount of money you have set aside for betting.
Volatility
The risk level of a slot or game. High volatility means fewer but larger wins; low volatility means frequent smaller wins.
Free Spin
The opportunity to spin in a slot game at no cost — usually triggered by a bonus or special symbol.
Spread
The expected score difference between two teams. In spread betting, you predict whether a team will win by the specified margin.
Wagering Requirement
The condition specifying how many times you must bet bonus funds before you can withdraw them. Example: a 10x wagering requirement means you must place ৳10,000 in bets for a ৳1,000 bonus.
