Deposits are typically credited within 1 to 5 minutes during business hours.

Nagad deposits on 31bd are processed within 1 to 5 minutes under normal conditions.

The minimum deposit on 31bd is ৳200 for mobile banking methods including bKash, Nagad, Rocket, and Upay. For bank transfers via Dutch-Bangla Bank, BRAC Bank, City Bank, Islami Bank, or Sonali Bank, the minimum deposit is ৳500.

Pragmatic Play titles, for example, typically carry RTPs in the 95–96.5% range. RTP is a theoretical long-term average and does not guarantee specific results in a single session. Each game's RTP is disclosed in its info or paytable section within the game interface.

31bd offers a welcome bonus to newly registered players on their first qualifying deposit. Bonus details — including the match percentage, maximum bonus amount in BDT, and any free spins — are confirmed on the current promotions page. Bonuses are subject to wagering requirements before withdrawal. Always read the full bonus terms before opting in, as requirements vary by promotion type and game contribution rates differ between slots and live casino.

A wagering requirement is the number of times you must bet your bonus amount before the resulting winnings become withdrawable. For example, a ৳1,000 bonus with a 20x wagering requirement means you must place a total of ৳20,000 in qualifying bets before requesting a withdrawal of bonus-derived funds. On 31bd, slots typically contribute 100% toward wagering, while live casino games may contribute a lower percentage. Check each promotion's individual terms.

Yes — 31bd regularly runs cricket-specific promotions during major tournaments including the Bangladesh Premier League (BPL), Indian Premier League (IPL), ICC T20 World Cup, and bilateral series involving the Bangladesh Tigers. These promotions typically include enhanced odds on selected matches, deposit reload bonuses in BDT, and free bet offers for pre-match and in-play markets. Check the 31bd promotions section at the start of each tournament for current offers.

No — bonus balances on 31bd cannot be withdrawn immediately. All bonuses must first satisfy their stated wagering requirements before the converted amount becomes eligible for withdrawal.

Once the wagering requirement is met in full, the bonus-derived winnings transfer to your withdrawable real-money balance automatically.

31bd rewards regular players through an ongoing loyalty programme. Players accumulate points based on their wagering activity across sports betting, slots, and live casino.

Contact 31bd support to find out your current tier status and how to advance.

Financial transactions are processed through verified payment gateways, and player funds are held in segregated accounts.

Bangladeshi players can use 31bd with confidence that their personal and financial data is protected.

Yes — 31bd offers a Time-Out feature that lets you temporarily suspend your account for 24 hours, 48 hours, 7 days, or 30 days. During a Time-Out, your account is locked for all betting and deposit activity, though you can still log in to withdraw any remaining balance. Time-Outs cannot be reversed early, so choose your duration carefully. This tool is ideal after a difficult session or when you simply need a break from gaming for personal reasons.
