hi31 Frequently Asked Questions

Creating an account on hi31 takes under two minutes — visit the hi31 website, click the registration link, and fill in your mobile number, preferred username, and password. You will need to be at least 21 years old to register. Once your basic details are submitted, you may be asked to verify your identity with a government-issued ID such as your National Identity Card (NID) or passport. After verification, your account is active and you can make your first deposit via bKash, Nagad, or Rocket.

hi31 requires a valid government-issued photo ID to complete account verification — your Bangladesh National Identity Card (NID), passport, or driving licence are all accepted. You may also be asked to provide proof of your payment method (for example, a screenshot confirming your bKash or Nagad number is registered in your name) and proof of address in some cases. Documents should be clear, unedited photographs or scans. Verification is typically completed within 24 hours of submission.

You can reset your hi31 password by clicking "Forgot Password" on the login page and entering the mobile number or email address linked to your account. A one-time password (OTP) or reset link will be sent to your registered contact. If you no longer have access to that number or email, contact the hi31 support team at [email protected] with your account details and a copy of your ID to verify ownership before a manual reset is processed.

No — hi31 strictly allows one account per person, per household, and per device. Operating multiple accounts is a violation of hi31's Terms and Conditions and will result in all duplicate accounts being permanently closed, with any associated balances forfeited. If you believe a duplicate account was created in error — for example, if a family member registered on the same device — contact support immediately so the situation can be reviewed before any enforcement action is taken.

To close your hi31 account permanently, contact the support team via live chat or by emailing [email protected] and request account closure. Before the account is closed, any remaining balance will be returned to your verified payment method — ensure your bKash, Nagad, or bank details are up to date. Note that if you are closing your account due to concerns about problem gambling, hi31 can apply a self-exclusion instead, which provides additional safeguards and is processed with priority care.

bKash deposits on hi31 are credited to your account instantly — in most cases within 30 seconds of a successful bKash transaction. If your deposit has not appeared after 5 minutes, check that the transaction reference number in your bKash app matches what you entered during the deposit process. If there is still a discrepancy, contact hi31 support with your bKash transaction ID and the support team will investigate and resolve the issue promptly, typically within one hour.

The minimum deposit on hi31 is ৳200 BDT, and the minimum withdrawal is ৳500 BDT — both amounts apply regardless of which payment method you use. These thresholds are designed to keep transactions practical for players across Bangladesh, whether you are using bKash, Nagad, Rocket, Upay, or a bank transfer via Dutch-Bangla Bank, BRAC Bank, or City Bank. There is no maximum deposit limit specified, though very large transactions may require additional verification under hi31's KYC policy.

hi31 does not charge its own processing fees on standard deposits or withdrawals — the amount you send is the amount that arrives in your account, and vice versa. However, your mobile money provider (bKash, Nagad, Rocket) or bank may apply their own standard transaction charges on their end, which are outside hi31's control. Always check the current fee schedule of your chosen payment provider. If you notice an unexpected deduction, contact hi31 support with your transaction reference for clarification.

Withdrawals via bKash and Nagad on hi31 are typically processed within 1 to 3 hours during normal operating hours; bank transfers may take 1 to 2 business days. Processing times can be slightly longer during peak periods such as BPL match days, Eid, or Pohela Boishakh when transaction volumes are higher. Your account must be fully verified before any withdrawal is processed. If your withdrawal has been pending for more than 6 hours without update, contact support at [email protected] with your withdrawal reference number.

As a general rule, hi31 requires withdrawals to be returned to the same payment method used for the original deposit — this is a standard anti-fraud and anti-money-laundering measure. For example, if you deposited via bKash, your withdrawal should go back to the same bKash number. If your original payment method is no longer accessible — for instance, if your SIM card was replaced — contact hi31 support in advance, submit the relevant documentation, and the team will review your case and advise on the approved withdrawal route.

hi31 covers a wide range of cricket betting markets including match winner, top batsman, top bowler, total runs, over/under run lines, and live in-play betting on BPL, IPL, T20 World Cup, and Bangladesh Tigers international fixtures. For BPL matches — which are among the most popular betting events for players in Dhaka, Chittagong, and Sylhet — hi31 offers ball-by-ball live markets during play. Exact market availability depends on the match and tournament; check the cricket section for the current schedule and available markets.

Yes — all slot and casino games on hi31 use certified Random Number Generator (RNG) technology, meaning every spin, card deal, and dice roll is statistically independent and cannot be predicted or manipulated. Games from providers such as Pragmatic Play, NetEnt, Microgaming, and Evolution Gaming are independently tested and carry Return to Player (RTP) certificates that hi31 publishes alongside each game. RTP figures for slots typically range from 94% to 97%, meaning the house edge is transparent and publicly disclosed.

hi31 is fully optimised for mobile play — the platform works smoothly on Android and iOS smartphones and tablets without requiring a dedicated app download. Simply open hi31 in your mobile browser (Chrome, Firefox, or Safari all work well) and the site automatically adapts to your screen size. All features available on desktop — including live cricket betting, slots, live casino, fishing games, deposits, and withdrawals — are fully accessible on mobile. A stable 4G or Wi-Fi connection is recommended for live casino and in-play betting.

Bombing Fishing and Butterfly Blossom are arcade-style shooting and collection games where players aim at targets to earn multiplied returns based on the difficulty and value of each target. In Bombing Fishing, players fire projectiles at fish of varying sizes and values — larger or rarer fish award higher multipliers. Butterfly Blossom follows a similar collect-and-multiply mechanic with vibrant floral visuals. Both games allow adjustable bet sizes per shot. Detailed in-game rules and paytables are accessible directly within each game interface on hi31.

The hi31 welcome bonus matches a percentage of your first deposit up to a stated maximum in BDT — for example, a 100% match up to ৳10,000 means a ৳5,000 deposit gives you ৳5,000 in bonus funds, for a total playing balance of ৳10,000. Bonus funds are subject to wagering requirements, which specify how many times the bonus amount must be staked before any winnings can be withdrawn. Always read the full terms of the current welcome offer in your account dashboard, as specific percentages and caps are subject to change.

A wagering requirement is the total amount you must bet using your bonus funds before those funds convert into real withdrawable money — for example, a 20x requirement on a ৳1,000 bonus means you need to wager ৳20,000 in total. On hi31, wagering progress is tracked automatically in your account's bonus section. Bets placed on slots typically contribute 100% toward the requirement, while live casino table games and sports betting may contribute a lower percentage. Check the specific contribution rates listed in the bonus terms for the promotion you have claimed.

Yes — hi31 runs regular promotions for existing players including reload bonuses on deposits, free spins on featured slots, cashback offers during major cricket tournaments like BPL and IPL, and seasonal specials around Eid and Pohela Boishakh. Players who opt into hi31's promotional communications receive notifications about new offers before they are publicly announced. You can manage your promotional preferences in your account settings. If you have applied a self-exclusion or cool-off period, promotional communications are automatically paused for the duration of that restriction.

hi31 uses industry-standard 256-bit SSL encryption on all connections, meaning your personal data, payment details, and account credentials are protected every time you access the platform. hi31 does not share or sell player data to third parties for marketing purposes. All payment processing routes — including bKash, Nagad, and Rocket — use their own independent security layers in addition to hi31's encryption. Players are encouraged to use a unique, strong password for their hi31 account and to enable two-factor authentication if available in their account settings.

hi31 provides a comprehensive suite of responsible gaming tools including deposit limits, loss limits, wager limits, session time reminders (reality checks), cool-off periods of up to 6 weeks, self-exclusion for 6 months to permanent, and promotional opt-out. All tools except self-exclusion can be activated directly in your account settings without contacting support. Self-exclusion requests should be directed to [email protected] to ensure they are processed with the appropriate level of care. Once a limit reduction or exclusion is activated, it cannot be reversed during the active period — this is by design.

The minimum age to register and play on hi31 is 21 years — no exceptions are made, and this applies to all players across Bangladesh regardless of location. Age is verified during the KYC process through government-issued ID documents such as your NID or passport. hi31 may request age verification at any time — including before processing a first withdrawal — and accounts that cannot confirm the player is 21 or older will be suspended pending document submission. If you suspect a minor has accessed a hi31 account, report it immediately to [email protected].
