Beware of fake sites & scams
Fraudsters may create fake sites and fake representatives using the name of 3k331 online. Follow the list below to keep yourself protected.
Always check the address bar — the official domain is 3k331.cam and there will be a green HTTPS lock.
Never share your OTP, bKash PIN, or Nagad PIN with anyone — 3k331 support will never ask for these.
Official support will never ask for your password — anyone who does is a fraudster.
Be cautious of anyone claiming to be a "3k331 agent" on Telegram or Facebook — these are not authorised.
If you have been scammed, change your password immediately and contact support via live chat.
Bankroll Management Guide
The most important aspect of responsible gaming is keeping control of your budget. This guide will help you enjoy a long-term, enjoyable gaming experience.
- Set a budget: Set aside a fixed amount each month for gaming that, even if lost, will not affect your daily life. Do not go beyond this limit.
- Divide into sessions: Split your total budget into smaller sessions. Rather than spending your entire budget in one session, keep a fixed portion for each day.
- Follow the 1–5% rule: Each bet should not exceed 1% to 5% of your total bankroll. This ensures longer-lasting gameplay.
- Stop after a win: After a big win, withdraw a portion. Keep some winnings safe rather than betting everything back.
- Respect your loss limit: End your session after losing a set amount. Placing larger bets to recover losses is dangerous.
- Keep a record: Track how much time and money you spend. This helps you stay aware of your own habits.
