78db's promotion system stands out in Bangladesh's online betting scene — no hidden terms, no sudden changes. Every offer is clearly explained so any player can understand exactly what they're getting.
Many sites require you to email support, contact customer service, or enter a promo code just to claim a bonus. At 78db, none of that is necessary. Your bonus is credited automatically as soon as your deposit is confirmed. Cashback is also paid out every Monday with no claim required.
The rollover requirement refers to how many times you must wager your bonus amount before withdrawing. At 78db, this requirement is lower than most other sites — for example, the cashback bonus carries just a 5x rollover, one of the lowest in the Bangladesh market.
It's not just Eid — 78db also runs special promotions for Puja, Independence Day, Victory Day, and major international cricket tournaments. During the Cricket World Cup or IPL, 78db's offers are at their best, featuring boosted odds, tournament prize pools, and free bet packages.
From Gazipur to Chattogram, Sylhet to Rajshahi — these offers are easily accessible from anywhere in Bangladesh via mobile. Pay with bKash or Nagad and your bonus is credited almost instantly.
The 78db referral program is straightforward. Grab your unique referral link from your profile and share it with a friend. Once they register through your link and make their first deposit, ৳500 is credited to your account instantly. Your friend also receives the full Welcome Bonus as a new member — a win for both of you.
This referral bonus has no rollover requirement and can be withdrawn directly. Many members use this program as a reliable source of extra income.
Each promotion has its own terms and conditions. Multiple bonuses cannot be active at the same time. For more details, Terms & Conditions Read.
