RTP and House Edge Explained
RTP, or Return to Player, is a percentage that shows how much of the total bets a game returns to players over the long term. If a slot has an RTP of 95%, then theoretically for every ৳100 wagered, an average of ৳95 is likely to be returned. However, this is an average across millions of rounds — results in a single session can vary widely.
Typical RTP ranges by game type are as follows: slot games 92–98%, Blackjack around 99%, and Roulette 94–97%. A higher RTP means the game keeps a relatively lower house edge over the long term, but it does not guarantee a win.
The house edge is the inverse of RTP — the portion the casino keeps. For example, a 96% RTP means a house edge of 4%. Volatility is another important concept: high-volatility games pay out large prizes less frequently, but the amount when you do win is greater. Low-volatility games pay out smaller wins more often.
It is wise to understand RTP and volatility before starting any game. This helps you plan your budget and set the right expectations.

Betting Terminology and Glossary
A simple explanation of common betting and casino terms for new players.
RTP (Return to Player)
The percentage of total bets a game returns to players over the long term. A higher RTP means the game pays back a relatively larger amount.
House Edge
The average share the casino keeps from each bet. For example, a 4% house edge means the casino keeps an average of ৳4 for every ৳100 wagered.
Wager / Stake
The amount of money you put at risk in each round or bet. Choosing the right stake is the foundation of bankroll management.
Odds
The ratio of the probability of an event occurring to the potential reward against it. Higher odds mean more risk but a greater reward.
Parlay / Accumulator
Combining multiple bets into one. If all selections are correct, the reward multiplies many times over, but if any one is wrong, everything is lost.
Live Bet
The ability to place bets in real time while a match is in progress. Odds change continuously based on how the match is unfolding.
Cashout
The option to take a guaranteed amount before a bet is settled. Useful for reducing risk or locking in a certain profit.
Bankroll
The total budget set aside for playing. Proper bankroll management is the most important strategy for sustaining play over the long term.
Volatility
The level of risk in a game. High volatility means big wins come less often but are larger when they do. Low volatility means smaller wins come more frequently.
Free Spin
The ability to spin the reels in a slot game at no cost. Usually given as part of a bonus or promotion.
Wagering Requirement
The condition specifying how many times a bonus amount must be wagered before it can be withdrawn. For example, a 25x wagering requirement means ৳25,000 must be wagered for a ৳1,000 bonus.
Spread
In sports betting, the set point difference between two teams. The outcome of the bet is determined based on this difference.
