How to Read Odds
Understanding odds before betting is important
Decimal Odds
Online betting platforms in Bangladesh typically use the decimal format. It is the simplest method. Example: you place a ৳500 bet at odds of 1.80 — if you win, you receive ৳500 × 1.80 = ৳900 (profit of ৳400).
Implied Probability
Odds tell you the implied chance of an outcome. Odds of 1.80 mean the bookmaker estimates the probability of that event occurring at around 55.6%. Calculation: 1 ÷ 1.80 × 100 = 55.6%. Lower odds mean a higher probability, but also a lower profit.
Other Formats at a Glance
| Format | Example | Meaning |
|---|---|---|
| Decimal | 1.80 | ৳1.80 returned for every ৳1 bet |
| Fractional | 4/5 | ৳4 profit for every ৳5 bet |
| American | -125 | ৳100 profit on a ৳125 bet |
RTP and House Edge Explained
Know before you play — essential information for informed players
What is RTP?
RTP, or Return to Player, is a percentage that indicates how much of the total amount wagered in a given game is returned to players over the long term. Example: if a slot has an RTP of 96%, it means an average of ৳96 comes back for every ৳100 wagered — however, this is a long-term mathematical average and the same result does not occur in every session.
RTP Ranges Across Different Games
RTP varies by game type. Slot games generally have an RTP between 92% and 98%. Skill-based games like blackjack can reach close to 99% RTP with the right strategy. For roulette, it typically falls between 94% and 97% — European roulette has a slightly higher RTP than American.
What is the house edge?
The house edge is the opposite of RTP. Subtract the RTP from 100% and you get the house edge. It is the casino's mathematical advantage — the average amount the casino keeps from each bet. Understanding the house edge means you can play with more realistic expectations.
Why does it matter?
A player who understands RTP and the house edge can make better decisions when managing their budget. Choosing games with a high RTP, using bonuses wisely, and playing within set limits — these three habits are the foundation of responsible and enjoyable play.

Cricket partnerships and industry trends
The trend of online gaming sponsorships in world cricket
Online betting companies around the world have placed cricket at the centre of their marketing. This partnership is growing deeper especially in cricket-loving countries like Bangladesh, India, Sri Lanka and Pakistan.
In recent years, platforms like Babu88 have linked up with Montreal Tigers and Colombo Strikers in international leagues. Crickex has been active as a sponsor in regional cricket initiatives in Bangladesh and India. Jeetbuzz has taken world-renowned all-rounder Andre Russell on as a brand ambassador — which makes clear the industry trend of using a single player as the face of a brand in the Bangladesh betting market.
This trend shows that cricket is not just a sport — it is the heart of Bangladesh's digital entertainment market. During the BPL season, interest in cricket betting rises noticeably from Dhaka to Chittagong. Demand for analytical betting content grows during the T20 World Cup or IPL.
