Security and Privacy
Account protection, data security and how to identify fake sites.
The real 399 bit site address is always https://399-bit.cam — check for "https" and the padlock icon at the start. Fake sites often use slightly different spellings, such as "399bit" or "399-bitt". Read the domain in the URL bar carefully before opening any site. If you are unsure, go to the 399 bit Login page and ask in live chat before logging in directly.
Change your password immediately and report it to the 24/7 live chat. The 399 bit support team can review suspicious login activity and temporarily lock the account. If you use the same password on other sites, change those too. Contact support by email to recover your account, and it is easier if you reach out from your registered mobile number.
Yes. 399 bit uses SSL encryption, which means all data passing between your device and the server is kept secure. Multiple layers of protection are also in place for storing personal information, payment data and transaction records. You can read the site's privacy policy for full details.
Never. No 399 bit staff member or support agent will ever ask for your OTP, bKash PIN, Nagad PIN or password. If anyone asks for these — by phone, chat or anywhere else — they are definitely a scammer. If you receive such a message, report it in live chat immediately and do not share any information.
Use a strong password — at least eight characters, mixing numbers and special symbols. Do not use the same password on any other site. Avoid logging in on public Wi-Fi. If you use the 399 bit app, only install it from official channels. Report anything suspicious to support straight away.
Slot Games
Player questions on jackpots, RTP, free spins and volatility.
In a progressive jackpot, a small portion of every bet is added to the jackpot pool, so the pool grows as more people play. There is no set time or guarantee for winning the jackpot — it is entirely random. Several progressive jackpot titles are available in the 399 bit slots section, where the pool amount is shown in real time.
RTP (Return to Player) is a theoretical percentage showing how much of total bets is returned to players over a long period. For example, Fortune Tiger has a maximum RTP of 96.81%, meaning that over the long run an average of ৳96.81 is returned for every ৳100 bet. However, this does not apply to each individual spin — it is an average across millions of spins.
Winnings from free spins generally go to the bonus balance, which cannot be withdrawn before the wagering requirement is met. Terms can vary by game or offer, so you should read the 399 bit terms and conditions carefully before taking free spins. Once the wagering requirement is met, the winnings move to your real balance.
Many slot games on 399 bit have a demo or free-play mode. Demo mode requires no real money and pays no real winnings — it is only for understanding the game features and how the spins work. To play with real bets, you need to fund your account with a minimum deposit of ৳100. Bonuses do not apply in demo mode.
Volatility describes how a slot distributes its payouts. High-volatility slots pay out less often but in larger amounts, while low-volatility slots pay out smaller amounts more frequently. For example, Dead or Alive 2 is known for high volatility, whereas Fortune Gems is comparatively steady. Consider your budget and risk tolerance before placing bets.
Cricket Betting
Questions and answers on rain delays, accumulators, BPL and in-play betting.
Generally, if a match is declared a no-result or abandoned, the bet is cancelled and the stake is returned. However, if a result is determined after a set number of overs have been completed (using the DLS method), the bet is settled accordingly. It is worth reading the cricket market rules on 399 bit before placing bets.
In an accumulator or multi-bet, all selections must win. If even one loses, the entire bet is lost. For example — three selections at odds of 1.40, 1.50 and 1.80: combined odds are 1.40 × 1.50 × 1.80 = 3.78. A ৳100 bet returns ৳378 if all three win; if one loses, the full ৳100 is lost.
Yes. 399 bit offers betting on the Bangladesh Premier League (BPL), IPL, T20 World Cup and Bangladesh Tigers international matches, along with other major tournaments. Various markets and odds are available, and particular attention is given to local matches for Bangladeshi players.
Yes, 399 bit's live in-play betting works equally well on a mobile browser and in the app. Odds change continuously while a match is in progress, so quick decisions matter. Select a market, enter your stake and the bet is confirmed.
The most popular markets are Match Winner (which team will win), Top Batsman, Over/Under runs and the time of the first wicket. In T20 matches, powerplay runs and the number of boundaries are also popular. All these markets are available together on 399 bit, and the cricket betting section has more details.
Live Dealer Games
Baccarat, Teen Patti, Roulette and live casino on mobile.
In Baccarat, you bet on either the Player or the Banker side (a Tie bet is also possible). Each side is dealt two or three cards; the side whose total is closest to 9 wins. 10s and face cards count as zero. Baccarat tables from Evolution and Pragmatic Play Live are available in the 399 bit live dealer section.
Yes, both games are available. In Teen Patti, you are dealt three cards and must form the best hand — a Trio (three of a kind) is the strongest. In Andar Bahar, the dealer reveals a joker card and you bet on whether the matching card will appear on the Andar or Bahar pile. Both games are fast and simple.
European Roulette has 37 slots (1–36 and one zero). Betting on red or black gives roughly a 48.6% chance — not 50%, because of the zero slot. American Roulette has two zeros, which reduces the odds further. It is a straightforward bet, but the house edge is always present.
No. The 399 bit live casino runs well on a mobile browser too. However, using the Android or iOS app may result in faster loading. The app is available from official channels. With a good internet connection, the live dealer video feed plays smoothly on mobile.
Withdrawal Questions
Minimum amounts, processing times and payment methods.
The minimum withdrawal amount on 399 bit is ৳500. You can withdraw via bKash, Nagad, Rocket and bank transfer. For bank transfer, major Bangladeshi banks including BRAC Bank, Dutch-Bangla Bank and Islami Bank are supported.
At 399 bit, withdrawal requests are usually processed within 5 to 30 minutes. This applies to all methods — bKash, Nagad, or Rocket. Occasionally, verification checks may add a little extra time, but long waits are generally not common.
A temporary "Pending" status after submitting a request is normal — it means the 399 bit team is reviewing it. Wait up to 30 minutes. If it is still pending after that, contact live chat with your transaction ID and ask for help. If there is any incomplete verification on your account, completing it will speed up the process.
Yes, 399 bit operates 24/7, so withdrawal requests are processed at night, on Fridays and on public holidays too. The standard 5–30 minute timeframe applies any day of the week at any time. If there is a delay in an unusual situation, you can report it in live chat.
Yes. Under 399 bit's rules, withdrawals can only be made to a bKash, Nagad, Rocket or bank account registered in the player's own name. Withdrawing to an account in someone else's name goes against the security policy and the request may be rejected.
