Betting Terms — A Guide for Beginners
New to online casino and betting? Knowing these terms will make playing easier.
RTP (Return to Player)
A general measure of what percentage of total wagers a game returns to players over the long term. This is a theoretical figure — it can vary from session to session.
House Edge
The mathematical advantage the casino holds in every game over the long term. A lower house edge means more opportunity for the player.
Wagering
The number of times you must bet the bonus amount before you can withdraw it. For example, 20x means you must wager ৳20,000 for a ৳1,000 bonus.
Odds
A way of expressing the probability of an event. Higher odds mean a higher return — but a lower chance of winning.
Stake
The amount of money you place on a specific bet. Always keep your stake within your means.
Parlay / Accumulator
A way to combine multiple bets together for the chance of a larger reward. All bets must win — if one loses, the entire bet is void.
Live Bet
The ability to place bets in real time while a match is in progress. Odds change every moment, so quick decisions are needed.
Volatility
A measure of how often and how large the rewards are in a slot game. High volatility means bigger jackpots — but less frequently.
Free Spin
The chance to spin a slot game for free without using your own money, usually given as a bonus.
Bankroll
The total budget set aside specifically for gaming. Experts always recommend sticking to a defined bankroll.
Cashout
The option to withdraw your bet before a match ends, usually available in live betting. Useful for securing a partial profit.
Spread
The points or runs difference between two teams or players, set by the bookmaker to balance the betting.
