RTP and House Edge — A detailed explanation
RTP, or Return to Player, is the percentage that a particular game pays back to players out of total bets placed over the long term. For example, if a slot game has an RTP of 95%, an average of ৳95 is returned for every ৳100 wagered — but this is an average figure and results may vary from session to session.
The typical RTP range varies across different game categories. Slot games generally show an RTP of 92%-98%, blackjack around 99%, roulette 94%-97%, and baccarat up to around 98.9%. Choosing games with a comparatively higher RTP is a sensible approach.
House edge is the opposite of RTP — it is the casino's advantage. For example, a game with 95% RTP has a house edge of 5%. The casino retains this margin over the long term, but any outcome is possible in the short term — so both luck and strategy matter.
Understanding volatility is also important. High-volatility games deliver larger rewards between wins, but you may have to wait a long time. Low-volatility games pay out smaller rewards more frequently. Knowing a game's RTP and volatility before you play will help you make more informed decisions.
Bankroll Management Guide
Budget control is the foundation of smart betting
1. Set a gaming budget
Only use money for gambling that, if lost, will not affect your daily life. Set aside a fixed amount each week or month and do not go beyond it.
2. Divide Your Sessions
Split your total bankroll into smaller session budgets. Instead of using the entire budget in one session, dividing it into 5-10 sessions lets you play longer and reduces the risk of a large loss.
3. The Per-Bet Rule — 1% to 5%
Do not place any single bet for more than 1%-5% of your total bankroll. This rule is widely accepted among professional bettors. With smaller bets, losing one bet does not end your entire session.
4. Stay Careful After a Win
When you have a good win, withdraw a portion of the winnings. Do not put everything back into play — this habit is the key to staying profitable in the long run.
5. Stop After a Loss
If you lose up to a set limit (for example, 50% of your session budget), stop playing. Do not fall into the trap of losing even more by trying to recover lost money all at once. Keep a record — understanding your own betting patterns will help you make better decisions.
