What are RTP and House Edge?
RTP, or Return to Player, is the long-term average payout rate of a game. For example, if a slot has an RTP of 96%, the expectation over the long term is that an average of ৳96 will be returned for every ৳100 wagered. This is not a guarantee for any single session — it is a mathematical average calculated across millions of spins.
House edge is the flip side of RTP. If the RTP is 96%, the house edge is 4%. House edge varies by game — in blackjack, using the correct strategy brings the house edge down to around 1%, the lowest among casino games. Slots typically have an RTP ranging from 92% to 98%, roulette from 94% to 97%, and blackjack can reach close to 99%.
Volatility, or variance, is another important concept. In high-volatility games, big wins come less frequently but the rewards are larger. In low-volatility games, wins are smaller but more frequent. Choosing the right volatility level based on your budget and playing style is a smart approach.
Understanding RTP and house edge before you place a bet helps you make informed decisions. Play responsibly — gaming is for entertainment, not a means of income.
Typical RTP Ranges by Game Type
| Game Type | Typical RTP | House Edge |
|---|---|---|
| Video Slots | 92%–98% | 2%–8% |
| Blackjack | ~99% | ~1% |
| Roulette (European) | 94%–97% | 2.7% |
| Baccarat | 98.9% | 1.06% |
| Crash Game (Aviator) | 95%+ | ~5% |
How a Betting Exchange Works
Unlike a traditional sportsbook, in a betting exchange you place bets against other players — not against the platform.
Back vs Lay — An Example
Say the odds on Bangladesh winning a Bangladesh vs India match are 2.5.
| Back (Support) | Lay (Opposition) |
|---|---|
| Bet that Bangladesh will win | Bet that Bangladesh will not win |
| Back ৳1,000 and win ৳2,500 on a win | You receive the equivalent of another Backer's loss |
| Same as traditional betting | Essentially playing the role of a bookmaker |
The exchange takes a small commission on each transaction — usually 2%–5% on winnings. The odds are set by the market, so you often get better value than with a regular sportsbook.
Sportsbook vs Exchange
| Feature | Sportsbook | Exchange |
|---|---|---|
| Odds Setting | Platform | Market / Players |
| Opponent | Bookmaker | Other Players |
| Lay Betting | No | Yes |
| Commission | Included in house edge | Separate on winnings |
