Cricket Partnerships — A Growing Trend in Bangladesh
The international online betting industry understands Bangladesh's cricket culture well. In recent years, several major brands have invested in cricket sponsorships.
Babu88 × Montreal Tigers
Babu88 raised its profile in the region by partnering with the Montreal Tigers and Colombo Strikers in the Caribbean tournament.
Crickex Regional Sponsorship
Crickex has built brand awareness across South Asia by sponsoring various cricket leagues and events in the region.
Jeetbuzz × Andre Russell
By making West Indies all-rounder Andre Russell a brand ambassador, Jeetbuzz gained wide recognition in Bangladesh and across South Asia.
Investment During BPL and T20 Season
Online betting platform sponsorships increase notably during the Bangladesh Premier League (BPL) and international T20 tournaments.
Betting Exchange — Bet Against Other Players
A betting exchange is completely different from a regular sportsbook — here the odds are set by other players.
Back vs Lay — The Key Difference
Back Bet: You think something will happen. Example — you bet ৳500 that Bangladesh will win the match. If Bangladesh wins, you receive a profit based on the set odds.
Lay Bet: You think something will not happen. Example — you bet that Bangladesh will not win the match. If Bangladesh does not win (draw or loss), you win.
On an exchange, a small commission is usually charged on each winning bet. This commission is generally lower than a bookmaker's margin.
| Feature | Back Bet | Lay Bet |
|---|---|---|
| You Want | The event to happen | The event not to happen |
| Risk | Stake amount | Potential liability (depends on the odds) |
| Example (৳) | ৳500 Bangladesh will win | ৳500 Bangladesh will not win |
| Source of Odds | The odds are set by other players | |
| vs Sportsbook | Against the house in sportsbook; against other players in exchange | |
