Crash is a fast-paced multiplier game available on 399det where a curve climbs from 1x upward and you must cash out before it crashes. The longer you wait, the higher your potential multiplier — but if the curve crashes before you cash out, you lose your bet. It combines skill, timing, and risk management, and is one of the most popular game types on the platform, especially among younger Bangladesh players. Try it in the Crash section.

399det offers a welcome bonus for new players upon their first deposit — the specific bonus amount and structure may vary depending on the current promotion period. Bonuses are credited to your account after your qualifying deposit clears. All bonus offers at 399det are subject to wagering requirements, which means you must wager the bonus amount a specified number of times before it can be withdrawn. Check the Promotions section after logging in for the latest welcome offer details.

A wagering requirement on 399det specifies how many times you must bet a bonus amount before you can withdraw the associated winnings. For example, a ৳1,000 bonus with a 20x wagering requirement means you must place ৳20,000 in total bets before the bonus converts to withdrawable cash. Wagers on different game types may contribute differently to wagering progress — slots typically contribute 100%, while live casino games may contribute less. Full terms are shown with each bonus offer.

Yes — 399det bonuses have an expiry period, typically 7 to 30 days from the date they are credited to your account, depending on the specific promotion.

Online gambling regulations in Bangladesh are complex and subject to change. 399det operates as an offshore platform and it is each player's personal responsibility to understand and comply with the laws applicable in their own jurisdiction before registering or playing. 399det does not provide legal advice. If you are uncertain about the legality of online gambling in your area, we recommend consulting a qualified legal professional before participating.

To self-exclude from 399det, email [email protected] with the subject line "Self-Exclusion Request" and state your preferred exclusion period — options include 3 months, 6 months, 12 months, or indefinitely. Your account will be locked within one hour of your verified request. During self-exclusion, your account balance will be returned in full and all marketing communications will stop immediately. Re-activating a self-excluded account requires a mandatory review and reflection period.

You can set daily, weekly, or monthly deposit limits on your 399det account through the Responsible Gaming section in your account settings, or by contacting our support team at [email protected]. Reducing a deposit limit takes effect immediately. Increasing a limit requires a 7-day cooling-off period before the new higher limit becomes active — this delay is intentional to protect you from impulsive decisions made in the heat of the moment. Learn more on our Responsible Gaming page.

You can contact 399det customer support by emailing [email protected]. Our team is available 24 hours a day, 7 days a week, and aims to respond to all enquiries within a few hours. For urgent responsible gaming requests such as self-exclusion or account locking, responses are prioritised and typically handled within one hour.
