What is RTP and House Edge?
RTP (Return to Player) is the percentage of total bets a game returns to players over the long term. For example, if a slot has an RTP of 96%, on average ৳96 comes back for every ৳100 wagered — but this is an average across billions of spins, not a guarantee for every round.
Typical RTP ranges by game type are roughly as follows: slot games generally 92%–98%, blackjack with correct strategy around 99%, European roulette around 97.3%, and baccarat around 98.9%. Keep in mind — a high RTP does not guarantee short-term winnings.
House Edge is the flip side of RTP. If a game's RTP is 96%, the house edge is 4%. This is the source of the casino's long-term profit. Understanding house edge matters because it helps you choose the right game.
Before you play, learn the RTP and volatility (high or low risk) of the game you choose. High-volatility games can pay out big wins but the gaps between wins are longer. This information helps you plan your budget.
Approximate RTP by Game
These are general approximate values. The RTP for a specific game can be found on the provider's site.
"A safe, transparent, and enjoyable betting experience for every player in Bangladesh — that is our commitment."
Bankroll Management Guide
Only spend on betting what you can afford to lose each month without it affecting your daily life. Never use money set aside for rent, food, or medicine for betting.
Split your total budget across multiple sessions. With a monthly budget of ৳3,000, keep to ৳100 per day or ৳750 per week — this reduces the risk of overspending in the heat of the moment.
Do not put more than 1%–5% of your session budget on any single bet. This rule means one bad run cannot wipe out your entire balance.
After a big win, withdraw a portion of your target amount and continue playing with the rest. Build the habit of not putting all your winnings back into bets.
Stop when you have lost the set amount for a session — do not place more bets trying to recover. Accepting a loss is the most important skill in bankroll management.
