Against Other PlayersCricket Partnership Trends
Sponsorship of online gaming platforms in Bangladeshi and international cricket is now a major industry trend. This has brought gaming culture further into the mainstream in Bangladesh.
For example, the Babu88 brand partnered with the Montreal Tigers and Colombo Strikers franchises in the International League T20. Crickex has taken up sponsorships in various regional T20 leagues. JeetBuzz signed West Indian all-rounder Andre Russell as a brand ambassador.
These kinds of partnerships show that cricket and online betting are deeply connected. Betting activity increases notably during BPL and IPL seasons, as cricket fans want to engage more deeply with their favourite teams.
What Is a Betting Exchange?
In a regular sportsbook, the betting company is your opponent — they set the odds and you bet against them. In a betting exchange, your opponent is another player. Odds are formed by players themselves, like a marketplace. The platform only takes a commission as an intermediary.
Practical example (in ৳): Say you think Bangladesh will win a T20 against Pakistan. You back them with ৳1,000 at odds of 2.0. Meanwhile, another player thinks Pakistan will win — they lay. If Bangladesh wins, you receive ৳2,000 (minus commission); if they lose, you lose ৳1,000.
| Back | Lay |
|---|---|
| Bet on an event happening | Bet on an event not happening |
| Like regular betting | You take on the bookmaker's role |
| Maximum profit: stake multiplied by odds | Maximum profit: the stake amount (liability is higher) |
| Matched against another player's lay | Matched against another player's back |
