RTP and House Edge Explained
RTP, or Return to Player, is the percentage a game returns to players over the long term. For example, if a slot has an RTP of 96%, it theoretically returns an average of ৳96 for every ৳100 bet — the remaining ৳4 is the house edge. However, this is an average calculated over hundreds of millions of spins; results in a single session can be completely different.
RTP ranges vary by game type. Online slots typically have an RTP of 92%–98%, Blackjack has an RTP of around 99% when played with correct strategy, and Roulette has an RTP of 94%–97% (higher for European Roulette). Table games generally have a lower house edge than slots.
The house edge is the casino's mathematical advantage — the percentage the casino retains from each game over the long term. The lower the house edge, the more favorable the game is for the player. For example, the house edge on the Banker bet in Baccarat is around just 1.06%, while some slots can have a house edge of 8%–10%.
Volatility, or variance, is another important concept. High-volatility games pay out larger amounts but less frequently, while low-volatility games pay out smaller amounts more often. Being aware of RTP and volatility before playing at an online casino helps you choose the right game for your budget and avoid unexpected losses.

Betting Glossary
If you are new to online casinos, knowing these terms will help you make better decisions.
RTP (Return to Player)
The rate at which a game returns a percentage of total bets to players over the long term. A higher RTP means a relatively better outcome for the player.
House Edge
The casino's mathematical advantage. It is calculated by subtracting RTP from 100%. The lower the house edge, the more favorable the game is for the player.
Wagering Requirement
The condition specifying how many times bonus money must be wagered before it can be withdrawn. Example: 25x means you must place a total of ৳25,000 in bets for a ৳1,000 bonus.
Volatility
The pattern of how winnings are distributed in a game. High volatility means larger wins less frequently; low volatility means smaller wins more frequently.
Free Spin
The opportunity to spin for free in a slot game, usually given as part of a bonus or promotion. Any winnings are added to the bonus balance.
Odds
A numerical expression of the probability of an event. The higher the odds, the greater the potential payout but the lower the probability. Odds can appear in decimal, fractional, and American formats.
Live Bet
A bet placed in real time while a match or game is in progress. Odds change moment to moment, creating specific opportunities for experienced bettors.
