A wide range of betting options on b399 — for everyone from beginners to seasoned bettors
A single bet on one match or event. The simplest and most straightforward option for beginners — lower risk, more control.
Combine multiple events into one bet and multiply the odds. Higher risk, but the potential payout is significantly larger.
Bet as the action unfolds. On b399, live odds update every few seconds in real time.
A handicap is applied to level the playing field between two sides. This creates opportunities even when betting against the stronger team.
Bet on whether the total runs, goals, or points will go over or under a set line. Hugely popular in cricket.
Place bets across various combinations from multiple selections. You can still turn a profit even if not all your picks win.
Many people want to get into betting but hold back because odds seem confusing. Once you get the hang of it, though, it's straightforward. b399 uses the decimal odds format, which is the most intuitive for users in Bangladesh.
Say you place a bet of 100 BDT with odds of 2.00. If you win, you receive 200 BDT — your original 100 BDT stake back plus 100 BDT in profit. The higher the odds, the bigger the reward, but the lower the likelihood of winning.
Compared to the market, b399 consistently offers some of the most competitive odds among platforms in Bangladesh — especially for cricket matches, where b399 odds are frequently the highest available.
