Know This Before Using Any Promotion
Bonuses and promotions play a big role in online betting, and 3999vi understands that well. From the start, the platform has been committed to offering its members genuinely worthwhile promotions — with terms that are easy to understand and bonus amounts that are realistic.
A common frustration for online betting users in Bangladesh is platforms that advertise big bonuses but bury the withdrawal process in complicated conditions. 3999vi does things differently. Wagering requirements are stated clearly, and claiming your bonus is kept simple.
Open a new account at 3999vi and get a 150% Welcome Bonus on your first deposit. Deposit ৳1,000 and you start with ৳2,500 in your account. The bonus is capped at ৳15,000, so a ৳10,000 deposit gets you the maximum benefit.
Many players worry that withdrawing after claiming a welcome bonus is complicated. At 3999vi, the Welcome Bonus wagering requirement is just 10x — well below the industry standard — making it much easier to actually benefit from the bonus.
Important: To receive the Welcome Bonus, your first deposit must be made within 72 hours of registration. The bonus is credited automatically — no bonus code required.
3999vi doesn't just look after new members. There are regular reload bonuses for long-time users of the platform too. Deposit a minimum of ৳1,000 every Monday and you'll receive a 50% reload bonus — a great way to kick off the week with a little extra in your balance.
Deposit during the last three days of the month and get a 75% monthly reload bonus. It's especially popular with high-stakes players. Though it can only be used once, the bonus amount can be substantial.
Wins and losses are both part of betting — but with 3999vi's cashback system, you never walk away empty-handed. Get 10% cashback on your daily losses, credited to your account by 8:00 AM the next morning. Daily cashback is capped at ৳5,000.
Weekly cashback just got better — up to 15%. To qualify, your net loss for the week must exceed ৳10,000. If you bet regularly, this is a benefit well worth having.
3999vi runs special promotions for Eid, Pohela Boishakh, Victory Day, and other significant occasions. During Eid, you can receive up to a 200% double bonus — the biggest offer available at any time of year. Pohela Boishakh comes with a 125% bonus, a special offer crafted to celebrate Bangladeshi culture.
Festive promotions are usually time-limited and go fast. Keep 3999vi notifications or the newsletter turned on so you never miss an offer.
The 3999vi referral program is simple and rewarding. Earn a ৳500 bonus for every successful referral, while your friend gets a 100% Welcome Bonus. There's no cap on referrals — the more friends you bring in, the more you earn.
Getting and tracking your referral link is simple. Just log in to your account and head to the "Referral" section to find your personal link. Share it and you're done.
In Bangladesh, cricket is more than a sport — it's a passion. 3999vi honours that passion by offering a special 30% betting bonus on Bangladesh national team match days. The bonus applies exclusively to bets on those matches, with a minimum bet of just ৳300.
Betting on Tigers match days at 3999vi is a different experience altogether — the thrill of the game combined with the added advantage of a bonus.
Members often miss out on promotions simply because a few basic rules aren't followed. Here's what to keep in mind to make sure you receive your 3999vi promotions. First, only one account is allowed per device. Second, withdrawing while a bonus is still active may result in the bonus being cancelled. Third, wagering requirements must be met before the bonus expires.
These rules are fairly standard across platforms. What sets 3999vi apart is its customer support team, available 24 hours a day to help with any issue you run into.
