RTP and House Edge Explained

What is RTP (Return to Player)?

RTP or "Return to Player" is a percentage that indicates how much money a game is expected to return on average for every ৳100 wagered over the long term. For example, a 96% RTP means there is an average chance of ৳96 coming back for every ৳100 bet. Keep in mind — this is an average calculated over millions of spins; in a single session it can be much higher or lower.

Typical RTP Ranges for Different Games

RTP varies across different casino games. Video slots typically have an RTP between 92% and 98%. Using correct strategy in blackjack can bring the RTP close to around 99%. European roulette generally has an RTP of 94%–97%, while American roulette is somewhat lower. Baccarat also tends to have a relatively high RTP.

What is House Edge and Why Does It Matter?

House edge is the mathematical advantage held by the casino or betting platform. If the RTP is 96%, the house edge is 4%. This means the casino earns an average of ৳4 from every ৳100 wagered over the long term. The lower the house edge, the more favorable the game is for the player.

Why Know RTP Before Playing?

When choosing a game, both RTP and volatility (level of risk) should be considered. Choosing a high RTP game increases the chance that your bankroll will last longer over time. Knowing this information before playing is the mark of a smart player.

Bankroll Management Guide

1. Set a Budget: Decide in advance the maximum amount you will spend on gaming each week or month and never exceed that limit. This is the first and most important rule of bankroll management.
2. Divide into Sessions: Split your total budget into smaller session portions. Allocate a separate amount for each session. This reduces the risk of losing all your money on a single bad day.
3. The 1–5% Rule Per Bet: Never place more than 1% to a maximum of 5% of your total bankroll on a single bet. This rule helps keep your funds going over the long term.
4. Stop After a Win: After a good win, set aside a portion of the profit and, if you want to keep playing, play only with what remains. Avoid putting all your winnings back on bets.
5. Respect Your Loss Limit: Decide in advance how much loss will make you stop for the day. Placing larger bets to recover losses (Chasing Losses) is the most dangerous habit.

Keep a Play History

Record the deposits, wins, losses and withdrawals from each session. This helps you understand which games you are more successful at and where you are losing money unnecessarily.
