Don't miss this special offer!
The online betting world is full of promotional offers. But on most platforms, the big bonus numbers you see are so hard to actually claim or use that players end up frustrated. b188 recognized this problem long ago.
When building each offer, we focus on two core questions — does this genuinely benefit the player? And can it be claimed easily? Only when both answers are yes does an offer make our list.
After registering as a new member at b188, a 150% bonus on your first deposit amount will be added to your account. For example, if you deposit BDT 1,000, your total balance will be BDT 2,500 — that's an extra BDT 1,500 completely free.
No separate code is needed to claim this bonus. Simply select the offer during your first deposit after registering, and you're done.
Yes, b188's cashback offer means real money back. If you have a net loss in any given week, you'll receive 10% of that loss back. "Net loss" means total bets placed minus total winnings. So if you bet BDT 10,000 in a week and win BDT 7,000, your net loss is BDT 3,000 — and you'll get BDT 300 cashback credited straight to your account.
Rollover (or turnover) is a condition that determines how much you need to wager before withdrawing your bonus funds. Here's a simple example: if you receive a bonus of BDT 1,000 with a rollover of x10, you'll need to place a total of BDT 10,000 in bets before you can make a withdrawal.
B188's rollover requirements are significantly lower than the market average. Our cashback bonus carries just a x3 rollover — less than almost every competitor out there.
Absolutely. Deposits via Mobile Banking, Nagad, and Rocket are all accepted at b188, and bonuses apply to all three methods. After depositing, the bonus is typically credited to your account within 5–15 minutes.
Mobile banking is the most popular payment method in Bangladesh, and b188 is built around that reality. No bank account or credit card hassle required.
Beyond Sports Betting, b188 also runs special promotions for Fish Games and casino games. Weekly tournaments are held on selected slots or fish games, with top players winning cash prizes. No separate entry fee is needed — just play and claim your spot on the leaderboard.
The b188 fish game section features multiple popular titles, each with its own bonus triggers and multipliers. Playing regularly earns you VIP points, which can later be converted into bonuses or cash.
