Diamond VIPCricket Format Guide
For cricket fans in Bangladesh, understanding the betting markets matters. Each format has its own set of markets.
T20
Each team plays 20 overs. Matches usually finish in 3 to 3.5 hours. The most popular format for live betting — markets shift with every over. BPL and IPL matches see the most action.
ODI (One-Day)
Each team gets 50 overs. Matches run for 7 to 8 hours. ODIs feature in the ICC World Cup and bilateral series. Top run scorer and wicket taker markets are popular in betting.
Test
A 5-day match with unlimited overs per innings. Team morale and pitch conditions play a big role in betting. The draw market is the most important one here.
The Hundred
A newer English format — each team plays 100 balls. Very fast-paced and done in just 2.5 hours. Betting markets are similar to T20.
Major Leagues
BPL (Bangladesh Premier League) — Bangladesh's own T20 league, a chance to watch the Tigers. IPL — the Indian Premier League, the world's most popular T20 tournament. BBL — Australia's Big Bash League, with night matches that fall in the early morning hours in Bangladesh. PSL — the Pakistan Super League, well known among fans across South Asia.

Popular Betting Markets
1X2 (Match Result)
Home win, draw or away win — pick the correct outcome from three options.
Double Chance
Cover two outcomes at once — lower risk, but also a comparatively lower reward.
Over / Under Goals
Bet on whether the total number of goals will be above or below a set number.
Both Teams to Score
The BTTS market — a simple bet on whether both teams will get on the scoresheet.
Asian Handicap
A weaker team is given an advantage to balance the market — very popular across Asia.
Live Betting
Place bets in real time while the match is in progress — odds update every moment.
Local Card Games
Familiar card games from South Asia can now be played online with live dealers and in multiplayer mode.
Teen Patti
Each player receives 3 cards. The strongest hand wins. Playing with a live dealer gives you the feel of a real casino. Start with small bets and learn by watching others play.
Live DealerAndar Bahar
One card is placed in the middle — you have to predict whether a card of the same value will land on Andar (inside) or Bahar (outside). Extremely simple and fast-paced. The ideal first game for beginners.
Simple RulesCallbreak
4 players compete to win tricks using a 52-card deck. Very popular in Nepal and Bangladesh. Spades are always the trump card — keep that rule in mind from the start.
MultiplayerLudo and Rummy
Familiar games from childhood now played online with real money prizes. In Ludo, 4 players roll dice; in Rummy, you build sets and runs. You play against other players.
MultiplayerFishing and Arcade Games
Fishing games are now one of the most popular categories in online casinos. Shoot underwater sea creatures with a cannon and win prizes based on each catch's value.
How It Works
- Cannon Level: A more powerful cannon can catch larger and rarer fish, but each shot also costs more.
- Fish Multiplier: Common small fish give smaller rewards, while boss fish or rare species offer much bigger prizes.
- Boss Fish: Massive boss fish appear from time to time — they take many shots to catch but the reward is equally huge.
Popular Arcade Types
🐟 Fishing Games
Mega Fishing, Ocean King Jackpot, Bombing Fishing — available in various themes.
💣 Shooter Games
Accurate aim and timely shots are the core skills required.
🎯 Crash Games
Cash out when you are happy with the multiplier — Aviator is one such game.
🎪 Arcade Sports
Penalty shootouts and basketball shooting — a mix of skill and strategy.
Tip: Keep the cost per shot under control. Start with a small cannon and spend no more than 10% of your balance per session.
Beware of Fake Sites and Scams
Scammers online create fake copies of well-known sites. Keep yourself protected.
The official site is always https://3b66.cam — confirm the lock icon and HTTPS in your browser. Any slight difference in the address (such as 3b66.cc or 3b66.net) means it is fake.
3b66 support will never ask for your bKash/Nagad PIN, OTP or password. If anyone asks, hang up immediately.
Many people on social media pose as "agents" and lure others with promises of extra bonuses. They are scammers — we have no agents.
Our support team contacts you only through the live chat inside the site. Do not trust messages coming from any other channel.
Change your password immediately. Then inform support via the site's live chat. If needed, also notify your mobile wallet provider.
Account Verification Process
KYC (Know Your Customer) verification ensures the security of your account and makes withdrawals faster. The process is simple and only needs to be done once.
Why KYC Is Required
Identity verification is essential for security and legal compliance. It keeps your account protected and helps prevent fraud.
Required Documents
National ID card (NID) or passport, a copy of proof of address, and a selfie. All documents must be clear and legible.
Processing Time
Verification is usually completed within 1 to 24 hours. It may take a little longer during busy periods, but support will keep you updated.
After Verification
Verified accounts get faster withdrawals, access to higher limits, and the ability to join the VIP program.
Responsible Gaming Tools
3b66 believes responsible gaming is everyone's right. We provide several tools to help you keep your gaming experience in check.
Deposit Limit
Set a maximum deposit limit on a daily, weekly, or monthly basis. Once set, reducing it takes effect immediately, but increasing it requires a cooling-off period.
Loss Limit
Take an automatic break after losing a set amount. Protects you from going beyond your budget.
Session Time Limit
After a set period you will receive a reality check reminder — letting you know how long you have been playing and how much you have won or lost.
Self-Exclusion
Options are available for a temporary break (1 day to 6 months) or permanent account closure. Contact live chat for assistance.
For players aged 21 and above only. If gaming feels like a problem, contact our 24/7 Bangla live support. To learn more, visit Responsible Gaming.
Betting Glossary
Common betting and casino terms are explained here in English for new players.
RTP (Return to Player)
The theoretical rate of how much of the total amount wagered in a game is returned to players over the long term. The higher it is, the more favorable it is theoretically for the player.
House Edge
The mathematical advantage built into every game in favor of the casino. The lower the House Edge, the better it is for the player. It is the flip side of RTP.
Wager
The condition specifying how many times you must place bets before you can withdraw bonus money. At 3b66, the wagering requirement for the welcome bonus is 15x.
Odds
Expresses the probability of a specific outcome and the potential amount to be won. There are three common formats: decimal, fractional, and American.
Parlay / Accumulator
Combining multiple bets together into one single bet. If all bets win, the reward multiplies significantly, but if one loses, the entire bet is lost.
Live Bet
Placing a bet in real time while a match or game is in progress. Odds change every moment, so quick decisions are required.
Cashout
The option to collect a partial or full win before the match ends. Used to reduce risk or lock in a guaranteed profit.
Volatility
A measure of how frequently and how large the rewards are in a slot or game. High volatility means less frequent but bigger wins.
Free Spin
A complimentary spin received as a bonus in a slot game. An opportunity to win rewards without spending your own balance.
Bankroll
The total amount of money set aside specifically for betting or gaming. Good bankroll management sustains long-term gaming.
Spread
Betting based on the point difference between two teams. Asian Handicap betting is a form of spread betting.
Stake
The amount of money you place on a single bet. The minimum stake at 3b66 is very low, so new players can get started easily.
