RTP and House Edge Explained
RTP (Return to Player) is a game's long-term statistical measure — it shows how much money, on average, comes back to players out of every ৳100 wagered over a long period. For example, if a slot has an RTP of 95%, theoretically ৳95 comes back for every ৳100 wagered. This is not a guarantee — actual wins or losses in a given session can differ significantly from the RTP.
RTP typically varies by game type. Slot games generally have an RTP ranging from 92–98%. Skill-based games like blackjack can reach ~99% with optimal strategy, as the house edge drops considerably. European roulette usually sits around 94–97%.
House Edge is the flip side of RTP. If the RTP is 96%, the house edge is 4%. That means over the long run, the casino keeps an average of ৳4 for every ৳100 wagered. This is the business model behind running a casino. Knowing the house edge before you play lets you enter a game with realistic expectations.
Why does understanding RTP and house edge matter? Because this information helps you make informed decisions — you can get a sense in advance of which game will make your budget last longer, and which game offers fewer big wins but more frequent small ones. This does not mean you will definitely win by playing high-RTP games — a random number generator (RNG) determines each spin independently.
Typical RTP by Game Type
| Game Type | Approximate RTP |
|---|---|
| Slots | 92–98% |
| Blackjack | ~99% |
| Roulette | 94–97% |
| Baccarat | ~98.9% |
| Crash Game | Variable |
These are general industry benchmarks — the RTP of a specific game may differ.

Crash Game — Fast Multiplier
Crash games like Aviator and JetX are currently very popular among players in Bangladesh. The rules are simple and each round lasts just a few seconds to a few minutes.
How It Works
As the plane or rocket takes off, the multiplier keeps rising. You can "Cash Out" at any time. If it crashes, anyone who has not cashed out loses their bet.
Auto Cash Out
You can set a multiplier in advance — when it is reached, your bet will cash out automatically.
Caution
Set a stop-limit for yourself before you start playing. Do not trust any "prediction" or "signal" groups — every round is completely random.
Betting Exchange — Back & Lay
In a regular sportsbook you bet against the casino. In a betting exchange you bet against other players — the odds are set by other users, not the casino.
Back Bet
You think the team will win — so you are backing them. Example: ৳500 bet backing Bangladesh.
Lay Bet
You think the team will not win — so you are laying them. In this case you take on a role similar to a small casino.
| Item | Back Bet | Lay Bet |
|---|---|---|
| Position | In favour of winning | In favour of losing |
| Potential Win | Odds × Stake | Original stake amount |
| Potential Loss | Stake amount | Liability |
| Example (৳500) | Win ৳1,000 if successful (Odds 2) | Receive ৳500 if they lose |
The exchange deducts a small commission from each winning bet — the exact figure depends on the user's volume and tier. In a regular sportsbook the casino sets the odds; in an exchange the market sets them.
