Games and How to Play
Cricket betting, slots, live casino and fair play
To bet on BPL (Bangladesh Premier League) matches, first log in to your ck31 account, then go to the cricket section. Select your preferred match from the match list, choose a market (such as match winner, toss, top batsman) and enter your desired amount to confirm the bet. Live betting is also available.
ck31 offers slot games from several well-known providers including Pragmatic Play, PG Soft and JILI. Popular titles such as Fortune Tiger, Fortune Gems, Gates of Olympus, Sweet Bonanza and many more are available to play. Fishing games, the crash game Aviator (Spribe) and live casino games are also available.
RTP (Return to Player) is the long-term average payout rate of a game, expressed as a percentage. For example, a 96% RTP means that on average ৳96 is returned to players for every ৳100 wagered. This is a theoretical figure and results in each session may vary.
All slots and casino games at ck31 are powered by RNG (Random Number Generator) technology, which determines the outcome of each round in a completely random and unbiased manner. Game providers ensure fair play through independent third-party audits.
Aviator is a crash game by Spribe. In each round a plane takes off and a multiplier increases. You need to cash out before the plane crashes. If you cash out at the right time, you win according to the multiplier on your bet. It is a fast-paced and exciting game.
Bonuses and Promotions
Welcome bonus, wagering requirements and VIP benefits
The ck31 welcome bonus is a 100% match bonus on your first deposit, up to a maximum of ৳8,000. After creating your account, simply make your first deposit of at least ৳500 and the bonus will be added automatically. A 10x wagering requirement applies to the bonus.
A wagering requirement means you need to place bets a certain number of times before you can withdraw bonus funds. For the ck31 welcome bonus, the wagering requirement is 10x. This means if you receive a ৳1,000 bonus, you must place a total of ৳10,000 in bets before withdrawing.
The ck31 VIP program has four tiers: Bronze (weekly cashback up to 0.4%), Silver (up to 0.8%), Gold (up to 1.1%) and Platinum (up to 1.5%). Playing regularly and placing more bets increases your tier. Higher tiers also come with special offers and faster support.
Each bonus has its own validity period, which is clearly stated in the offer's terms and conditions. Generally, if the wagering requirement is not completed within the specified time after the bonus is credited, the bonus may be cancelled. Visit the terms and conditions page for full details.
ck31's promotional offers change from time to time. To find out about the latest offers including any referral program, check the promotions page or ask via live chat. Keep your registered email active to receive notifications about new offers.
