RTP and House Edge Explained
RTP (Return to Player) is the percentage of total bets that a game returns to players over the long term. If a slot game has an RTP of 96%, it theoretically returns an average of ৳96 for every ৳100 wagered — however, this is a long-term average only, and results in a single session will vary.
The typical RTP ranges for different types of games are: slot games generally offer 92%–98% RTP, Blackjack can reach ~99% with the correct strategy, and Roulette (European) typically falls within 94%–97%. Understanding these differences helps you decide where playing is more favorable.
House Edge is the flip side of RTP — the average percentage the casino keeps from each bet. For example, a 96% RTP means a 4% house edge. The lower the house edge, the more favorable the conditions are for the player.
Knowing these things before choosing a game allows you to make more informed decisions, helps your bankroll last longer, and makes the gaming experience more enjoyable.
Betting Terminology Glossary
Simple explanations of common betting and casino terms for new players.
RTP
Return to Player — a measure of what percentage of total bets a game returns to players over the long term.
House Edge
The percentage the casino keeps on average from each bet. It is the opposite of RTP; a lower house edge is better for the player.
Wager / Stake
The amount of money placed on a specific bet. Both "Stake" and "Wager" mean the same thing — the amount bet.
Odds
Indicates the probability of a bet and the potential reward. High odds mean a lower chance of winning but a bigger reward.
Parlay / Accumulator
Combining multiple bets into one larger bet. If all bets win, the reward multiplies significantly.
Live Bet

Cashout
The option to collect your winnings based on the current value of your bet before the game ends.
Bankroll
The total budget set aside for your gaming. Sound bankroll management is the foundation of responsible play.
Volatility
A measure of how often and how large the payouts of a slot game are. High volatility means fewer but bigger wins.

Wagering Requirement
