RTP and House Edge Explained
RTP, or Return to Player, is the theoretical percentage of total wagered money that a game pays back to players over the long term. For example, if a slot has an RTP of 96%, it returns an average of ৳96 for every ৳100 wagered — but this is not a guarantee for a single session; it is the average across millions of spins.
It is useful to know the typical RTP ranges for different games: slot games are generally 92%–98%, blackjack is around 99%, and roulette can range from 94%–97%. To achieve blackjack's high RTP, knowing the correct strategy is essential.
House edge is the flip side of RTP — subtract the RTP from 100% to get it. For example, a 96% RTP means a 4% house edge. The casino profits over the long term from this small margin.
Knowing a game's RTP before you play helps you understand which games are more cost-effective to play for longer periods. Keep in mind, though — RTP is a long-term statistic; any result is possible in the short term.
Bankroll Management Guide
The first rule of smart play is setting a fixed budget. Decide in advance how much money you can set aside for entertainment each week or month, and do not go beyond that limit. Never bet with borrowed money.
Divide your total bankroll into smaller session amounts. Use only that portion each session — this reduces the risk of losing everything in one day and makes the fun last longer.
Many experienced players follow the "1–5% rule" — meaning no single bet exceeds 1% to 5% of their total bankroll. This gives you a chance to survive a long losing streak.
Set a target at which you will stop after winning. Many players follow the rule of "stop when I'm up 20%". Similarly, set a loss limit — for example, stop when 50% of your session bankroll is gone.
Track your play history — when you played, how long, and how much. This helps you understand your own patterns. If you need help, read our responsible gaming page.
