A Guide to Understanding RTP and House Edge
RTP, or "Return to Player", is the percentage of total wagered money that a game pays back to players over the long term. For example, if a slot game has an RTP of 96%, there is theoretically a chance of ৳96 being returned for every ৳100 wagered. However, this is a long-term mathematical average — results in a single session may vary.
Typical RTP ranges by game type are as follows: slot games generally have an RTP of 92–98%. In Blackjack, following the correct strategy can bring the RTP close to 99%. Roulette typically falls between 94–97%.
House edge is the opposite side of RTP — it is the casino's mathematical advantage. If a game has an RTP of 96%, the house edge is 4%. This means the casino retains an average of ৳4 for every ৳100 wagered over the long term.
Why is it important to know this? Because it helps you make informed decisions — which games to play, how to manage your budget and what expectations to keep realistic. Remember, gambling is always for entertainment — never think of it as a source of income.
