Games & How to Play
To bet on BPL or any cricket match, log in to 3d666 and go to the Cricket section. Select the match you want, choose a market (match winner, toss, top run-scorer, etc.), and set your bet amount. You can also bet on live matches at real-time odds.
RTP, or Return to Player, is the theoretical percentage of total wagered money that a game returns as winnings over the long term. For example, a 96% RTP means that on average ৳96 is distributed as winnings for every ৳100 wagered — but this is an average across millions of spins, not a one-time guarantee.
Yes. 3d666 offers live casino games from top providers including Evolution Gaming and Ezugi. You can enjoy live roulette, blackjack, baccarat, and many more games with real dealers. With a good internet connection, gameplay is seamless on mobile as well.
Aviator by Spribe is a crash game — a plane takes off and a multiplier keeps increasing. You need to cash out before the plane crashes. If you do not cash out in time, your bet is lost. The game is simple but requires quick decision-making.
3d666 only uses games from certified software providers that employ Random Number Generator (RNG) technology. This ensures every game result is completely random and manipulation in favour of any party is not possible. We are committed to maintaining a transparent and fair gaming environment.
Bonuses & Promotions
New members receive a 100% bonus on their first deposit — up to ৳5,000. That means depositing ৳5,000 lets you start playing with ৳10,000 in total. The bonus is applied automatically — no separate code required. The bonus is added on the first deposit after account registration.
The wagering requirement for the welcome bonus is 15 times. That means you need to wager 15 times the bonus amount before becoming eligible to withdraw. For example, if you receive a ৳1,000 bonus, you need to wager a total of ৳15,000. If the requirement is not met within the set time, the bonus may expire.
3d666's VIP program has three tiers. The Bronze tier offers up to 0.3% cashback per week. The Silver tier increases this to up to 0.5%. The top Gold tier offers up to 0.8% weekly cashback. Playing regularly naturally moves you up to higher tiers.
Yes. 3d666 regularly offers various promotions — such as reload bonuses, cashback offers, tournament prizes, and additional offers on special occasions (BPL, IPL, T20 World Cup, Eid). Check the Promotions section of your account regularly for the latest offers.
Depending on the bonus terms, specific games or betting markets may apply. In most cases, wagering bonus funds on slot games is straightforward. To find out the detailed terms of a specific bonus, check the Promotions page or ask our support team.
