Open an AccountA guide to understanding RTP and house edge
These are essential concepts to know before investing in any game.
What is RTP (Return to Player)?
RTP, or Return to Player, is a game's theoretical return rate — a measure of how much money is paid back to players on average per ৳100 wagered over the long term. For example, a 96% RTP means an average of ৳96 is returned for every ৳100 wagered, with the casino keeping ৳4. Keep in mind that RTP is an average calculated over millions of spins — results in a single session can be completely different.
Typical RTP ranges across different games
RTP varies by game type. Slot games generally have an RTP ranging from 92% to 98%. Blackjack played with the correct strategy can have an RTP close to 99%. European roulette typically has an RTP of around 94% to 97%. Baccarat has a comparatively higher RTP and lower house edge.
What is the house edge?
The house edge is the casino's mathematical advantage — the counterpart to RTP. If the RTP is 96%, the house edge is 4%. This does not mean you will always lose — a big win in the short term is entirely possible. The house edge simply defines the casino's long-term earnings structure.
Why is it important to know this?
Knowing the RTP and house edge helps you make more informed decisions. Choosing games with a higher RTP can help your budget last longer over time. That said, play to enjoy the game — choose the games you like rather than deciding purely based on RTP. Always practice responsible gaming and stay within your set budget.
Cricket sponsorships and industry trends
The relationship between online betting and cricket in Bangladesh is deepening day by day. International betting platforms are increasingly interested in forming partnerships with cricket teams.
For example, Babu88 has signed sponsorship deals with Montreal Tigers and Colombo Strikers in international leagues. Crickex has become involved with various regional cricket events, and Jeetbuzz has appointed Andre Russell as a brand ambassador.
Industry trends show that Bangladeshi cricket fans are most active on betting platforms during major tournaments like BPL, IPL, and T20 World Cup. Every Bangladesh Tigers match is now becoming a global event.

House Edge

Wager / Stake
