RTP and House Edge Explained
RTP, or Return to Player, is the theoretical percentage of total bets that players get back over the long term in a game. For example, if a game has an RTP of 95%, it is expected to return an average of ৳95 for every ৳100 wagered — however, this is an average across millions of spins, not a guarantee for every session.
House edge is the other side of RTP — it is the percentage the casino keeps. If the RTP is 95%, the house edge is 5%. House edge varies across different games: slots typically have an RTP of 92–98%, blackjack around 99%, and roulette up to 94–97%.
Volatility, or variance, refers to the frequency and size of wins in a game. High-volatility games pay out less often but in larger amounts. Low-volatility games pay out smaller wins more frequently. Choose the right game based on your bankroll and patience.
Understanding RTP and house edge helps you make more informed betting decisions. It does not guarantee winnings, but gives you an idea of the long-term mathematics behind each game.
| Game Type | Typical RTP Range |
|---|---|
| Slot Games | 92% – 98% |
| Blackjack | Approximately 99% |
| Roulette | 94% – 97% |
| Baccarat | Approximately 98.9% |

Get Started NowBetting Terminology Glossary
Simple explanations of common betting and casino terms for new players.
RTP (Return to Player)
The theoretical rate at which a game returns a percentage of total bets to players over the long term. A higher RTP means less potential loss over time.
House Edge
The percentage advantage the casino holds on average for every bet. The lower the house edge, the better it is for the player.
Wager / Stake
The amount of money placed on a single bet is called the wager or stake. A wagering requirement on a bonus means you must bet the bonus amount a specified number of times.
Odds
A way of expressing the probability of an event occurring. Expressed in decimal, fractional, or American format. Higher odds mean lower probability but a larger payout.
Parlay / Accumulator
Combining multiple bets together. If all bets are correct, you win big; if even one is wrong, the entire stake is lost. Higher risk, higher reward.
Live Betting / In-Play
The ability to place bets in real time while a match is in progress. In cricket, odds change every over or ball.
Cashout
The option to settle a bet partially or fully before the match ends. Used to secure a safe profit or reduce losses.
Bankroll
The total budget set aside for betting. Proper bankroll management is the key to responsible play.
Free Spins
Free slot spins provided by the casino. Winnings from bonus free spins are generally withdrawable subject to wagering conditions.
Volatility
The level of risk in a game. High volatility means big wins come less frequently. Low volatility means smaller wins happen more often.
Spread Betting
Betting on whether a result will be higher or lower than a predicted range. Run spreads are popular in cricket.
Wagering Requirement
The condition specifying how many times the bonus amount must be wagered before withdrawal. Example: a ৳1,000 bonus with a 25x requirement means you must bet ৳25,000.
