RTP and House Edge Explained
RTP (Return to Player) is a theoretical percentage representing how much a game returns to players over the long term. For example, a 96% RTP means that for every ৳100 wagered, an average of ৳96 is returned — however, this does not apply to every individual session; it is an average calculated over millions of rounds.
Typical RTP ranges by game type: slot games generally 92–98%, blackjack around 99%, roulette 94–97% (European), and video poker up to 95–99.5%.
House Edge is the opposite of RTP — it is the casino's average advantage. A 96% RTP means a 4% house edge. This does not mean you will necessarily lose — any outcome is possible in the short term.
Understanding RTP and house edge before you play helps you make informed decisions. A higher RTP means a lower chance of loss over the long term — but responsible gaming is always the most important thing.

Betting Terminology Glossary
Learn the common terms used in online betting and casino in plain English.
RTP (Return to Player)
The theoretical percentage of total wagers that a game returns to players over the long term. Example: a 96% RTP means an average of ৳96 is returned for every ৳100 wagered.
House Edge
The casino's average mathematical advantage on every bet. A 4% house edge means a 96% RTP — over the long term, the casino keeps an average of ৳4 per ৳100.
Wager / Stake
The amount of money you put at risk in a specific round or bet is called a stake or wager.
Odds
Expresses the probability of a specific outcome. In betting, the higher the odds, the lower the chance of winning — but the reward is greater if you do win.
Parlay / Accumulator
Combining multiple bets together. If all bets are correct, the reward multiplies — but if even one is wrong, the entire bet is lost.
Live Bet
A bet placed in real time while a match or game is in progress. Also known as in-play betting. Odds change at every moment.
Cash Out
The option to secure a portion of your bet before the match or game ends. Used to reduce risk or lock in a guaranteed profit.
Bankroll
The total amount of money set aside specifically for gaming. Good bankroll management is the foundation of responsible gaming.
Volatility
Refers to the frequency and size of rewards in a slot game. High volatility means fewer but larger rewards; low volatility means frequent but smaller rewards.
Free Spin
Free slot rounds given as a bonus. An opportunity to play the game and win rewards without spending your own money.
Wagering Requirement
The condition specifying how many times the total bonus amount must be wagered before it can be withdrawn. At l6666, the wagering requirement for the welcome bonus is 10x.
Spread
In sports betting, the point difference between two teams set by the bookmaker. In spread betting, the margin matters more than the result.
