RTP and House Edge — Play with Understanding
What is RTP (Return to Player)?
RTP, or "Return to Player rate," is the percentage of total bets placed in a game that is paid back to players as winnings over the long term. For example, if a slot has an RTP of 96%, it means that on average ৳96 is paid out as winnings for every ৳100 wagered.
Typical RTP Ranges for Different Games
- Video Slots: Generally between 92% – 98%
- Blackjack: Up to approximately 99% with the right strategy
- Roulette: Around 94% – 97% for European Roulette
- Baccarat: Approximately 98.94% on the Banker bet
What Does House Edge Mean?
House edge is the opposite of RTP — it is what the casino keeps on average from each bet. A 96% RTP means a 4% house edge. This is the source of the casino's operating costs and profit. Keep in mind that RTP is a long-term average — results in a single session can vary.
Why Is This Worth Knowing?
Being aware of RTP and house edge helps you understand which games offer a more favorable position over the long term. Choosing high-RTP games is a smart strategy — but remember, each round is completely independent and past results have no effect on the next round.
