RTP and House Edge Explained
RTP, or Return to Player, is a percentage that indicates how much of the total amount wagered on a game is paid back to players over the long term. For example, if a slot has an RTP of 96%, theoretically ৳96 comes back for every ৳100 wagered — but this is an average over millions of spins, not a guarantee for any single session.
Typical RTP ranges for different games: slot games are generally 92%-98%, blackjack can reach around 99% with correct strategy, and roulette offers 94%-97% RTP.
House edge is the opposite concept to RTP — it is the percentage the casino keeps over the long term. Subtract the RTP from 100% and you get the house edge. Choosing games with a lower house edge reduces a player's long-term losses.
Understanding RTP and volatility before you play is important. High-volatility games pay out big wins less frequently; low-volatility games deliver smaller wins more often. Choose your game based on your budget and risk tolerance.
Bankroll Management Guide
Responsible gaming is not just about entertainment — it is also about financial protection. Follow the guidelines below.
- Set a budget. Decide how much you can afford to spend before you start playing. Treat this money as an entertainment expense — never use funds set aside for essential needs.
- Divide it into sessions. Split your total budget into smaller sessions. Rather than playing all your money at once, set a separate limit for each session so that one bad session does not wipe everything out.
- Follow the 1-5% rule. Do not use more than 1% to a maximum of 5% of your total bankroll on any single bet. This rule keeps your balance going over the long term.
- Take a break after a win. After a good win, consider ending that session. The "just one more" mindset often gives the winnings back. Set a specific profit target in advance.
- Stop when you hit your loss limit. If you have lost 50% of your session budget, that is your signal to stop. Placing larger bets to recover lost money is the most dangerous decision you can make.
- Track your gaming history. Keep a note of how much you deposited, how much you withdrew, and how long you played. Regular reviews will help you understand your own patterns and make better decisions.
