RTP and House Edge Explained
What is RTP?
RTP, or Return to Player, is a percentage that shows how much of total wagers a game returns to players over the long term. For example, if a slot has an RTP of 96%, it means that on average ৳96 is returned for every ৳100 wagered over the long term. This is not a guarantee for any single session — it is an average calculated over millions of spins.
Typical RTP ranges for different games
Slot game RTP generally falls between 92% and 98%. Blackjack played with the correct strategy can reach an RTP close to 99%. Roulette RTP depends on the table type — European roulette is around 97.3%, while American roulette is comparatively lower. Baccarat offers an RTP close to 98%.
What is House Edge?
House edge is the other side of RTP — the portion the casino keeps. For example, a 96% RTP means a 4% house edge. This is not a bad thing; it covers the casino's operating costs. Games with a lower house edge are generally more favorable over the long term.
Why does this matter?
Understanding RTP and house edge helps you make informed decisions. Choosing games with a higher RTP means your money will last longer over time. Remember, gaming should always be for entertainment — never bet with money you need for essential expenses.
Note: RTP data is taken from general ranges published by game providers. You can check the RTP of a specific game on the game provider's website.
How to Read Odds
Odds are the way a betting event's probability and potential payout are expressed. Different formats are used in different countries. Decimal odds are most commonly used in Bangladesh.
Decimal Odds — Example
You place a bet of ৳500 at odds of 1.80.
If you win, you receive a total of ৳900 (including your original stake of ৳500), for a net profit of ৳400.
Implied Probability
To work out probability from decimal odds: 1 ÷ odds × 100. Example: 1 ÷ 1.80 × 100 = 55.6%. This is the probability the betting operator is assuming.
Fractional Odds
This format is commonly used in the United Kingdom. 4/5 means ৳4 profit for every ৳5 wagered. So on a ৳500 bet, profit = ৳500 × 4/5 = ৳400, total return ৳900.
American Odds (Moneyline)
+180 means ৳180 profit on a ৳100 bet. -180 means you must wager ৳180 to win ৳100. This format is mainly used in American sports betting.
A Simple Comparison
| Decimal | Fractional | American | Probability |
|---|---|---|---|
| 1.50 | 1/2 | -200 | 66.7% |
| 2.00 | 1/1 | +100 | 50.0% |
| 3.00 | 2/1 | +200 | 33.3% |

Crickex Regional Sponsorship
Crickex has established its presence in the Bangladesh and Indian cricket markets through regional sponsorships — particularly around T20 format tournaments.
Jeetbuzz & Andre Russell
Jeetbuzz has signed Caribbean cricketer Andre Russell as a brand ambassador — a well-recognised face among cricket-loving betting audiences in Bangladesh.
