What Are RTP and House Edge?
RTP (Return to Player) is a game's long-term theoretical payout percentage. For example, if a slot has an RTP of 96%, then in theory an average of ৳96 is returned for every ৳100 wagered. However, this is an average calculated over millions of spins — results in a single session can be completely different.
Generally speaking, slot game RTP typically falls between 92% and 98%. Card games like blackjack can approach an RTP of around 99% when the correct strategy is applied. Roulette RTP usually ranges from 94% to 97%, depending on which variant you are playing.
House edge is the flip side of RTP — it is the percentage representing the casino's average advantage. If RTP is 96%, the house edge is 4%. This does not mean you will always lose; rather, it is a numerical expression of long-term probability.
Understanding RTP before you play helps you set a more informed budget and keep your expectations realistic. Games with higher RTP generally allow longer play time. Considering volatility and RTP together makes it easier to find which game suits your playing style.
Quick Facts
- Slot RTP: typically 92–98%
- Blackjack RTP: ~99% with correct strategy
- Roulette RTP: 94–97%
- Volatility: Low = frequent small wins, High = rare large wins
- Fair Play: All games are RNG-certified
Glossary — A Guide for Beginners
Understand the key terms used in casino and sports betting.
RTP (Return to Player)
A game's long-term theoretical return percentage. A higher RTP means theoretically more return for the player.
House Edge
The casino's mathematical advantage. Subtract RTP from 100% to get the house edge.
Wager / Stake
The amount of money you place on each bet — your wager or stake. Always keep it within your budget.
Odds
A numerical expression of the probability of an event occurring. The higher the odds, the greater the potential winnings.
Parlay / Accumulator
Combining multiple bets into one. If all bets win, the reward multiplies significantly, but if any single bet loses, the entire wager is lost.
Live Bet
A bet placed in real time while a match or game is in progress. Odds change from moment to moment.
Cashout
The option to settle a bet before the match ends. Used to lock in a profit or reduce a loss.
Bankroll
The total funds set aside specifically for playing. Healthy bankroll management is the foundation of responsible gambling.
Volatility
The level of risk in a game. High volatility means large wins come occasionally; low volatility means small wins come frequently.
Free Spin
Spins received as a bonus at no cost. An opportunity to win prizes on slot games without spending your own money.
Wagering Requirement
The condition specifying how many times the bonus amount must be wagered before it can be withdrawn. At a71b this is 20 times.
Spread
The difference between the buying and selling odds. In sports betting it forms part of the bookmaker's commission.

a71b believes gaming should be enjoyable — never stressful. We have put several tools in place for your safety.
Deposit Limit
