RTP and House Edge Explained
RTP (Return to Player) is the percentage of total bets a game returns to players on average over the long term — for every ৳100 wagered. For example, a 96% RTP means an average of ৳96 is returned. This is not a guarantee for individual sessions — it is a statistical average.
RTP typically varies across different types of games. Slots generally have an RTP between 92% and 98% — meaning the casino edge is between 2% and 8%. Skill-based games like blackjack can reach an RTP of nearly 99% with the right strategy. Roulette typically has an RTP between 94% and 97%.
House Edge is the opposite of RTP — it is how much the casino retains on average. Subtract the RTP from 100% to get the house edge. It is a necessary business element that keeps the game running.
Understanding RTP and volatility before choosing a game is important. High-volatility games offer a greater chance of big wins but less frequent wins. Low-volatility games pay out smaller wins more often. Choose the right game based on your budget and preference.
