Game Types Explained
New to online gaming? Here is a clear breakdown of each major category available on b399, so you can pick the right game for your style and budget.
🏏 Cricket Betting
Bet on BPL, IPL, T20 World Cup, ODIs, and Test matches. Markets include match winner, top batsman, total runs, live in-play bets, and multi-leg accumulators. The most popular category for Bangladeshi players, particularly during the BPL season in Dhaka.
🎰 Slot Games
Hundreds of video slots from Pragmatic Play, NetEnt, Microgaming, and Spribe. Each slot has a published RTP (Return to Player) percentage, typically between 94% and 97%. Volatility ranges from low (frequent small wins) to high (rare but large payouts).
🃏 Live Casino
Real-time games streamed from professional studios via Evolution Gaming and Ezugi. Play Live Baccarat, Live Roulette, Live Blackjack, and Live Andar Bahar with English-speaking dealers available 24/7. Stakes start from ৳50 per hand.
🎲 Table Games
Classic Baccarat, Roulette (European and American), Blackjack, and Sic Bo in digital format. Table games offer some of the lowest house edges on the platform, making them a favourite among strategic players with larger bankrolls.
🀄 Teen Patti
South Asia's most beloved card game — sometimes called Indian Poker. b399 offers both classic and Joker variants. The game uses a standard 52-card deck; three cards are dealt per player. Simple rules make it accessible for beginners across Dhaka and Chittagong.
🎴 Andar Bahar
A traditional card game popular across the subcontinent. A single card is drawn as the "joker", and players bet on which side — Andar (inside) or Bahar (outside) — the matching card will appear. Fast rounds and near 50/50 odds make it a beginner favourite.
🎱 Bingo
Online bingo at b399 runs on scheduled and instant formats. Players purchase cards and mark off numbers as they are called. Prize pools are fixed or progressive. Bingo rooms on b399 support chat features and operate around the clock.
🚀 Crash Games
Fast-paced multiplier games like Aviator from Spribe. A multiplier climbs from 1x upward; players must cash out before the graph crashes. The longer you wait, the higher the potential payout — but the risk rises too. Rounds last as little as 10 seconds.

Sports Betting Education
Cricket Formats Explained
Understanding the format you are betting on is the single most important step for any cricket bettor. Each format has its own rhythm, markets, and strategic approach.
T20 — Twenty20
Each team faces exactly 20 overs (120 balls). A typical T20 match lasts 3 to 3.5 hours. The fast pace means explosive batting, high run rates, and frequent momentum shifts — making it ideal for live in-play betting. Key markets include total sixes, top batsman, and first-wicket method. BPL (Bangladesh Premier League), IPL (Indian Premier League), and T20 World Cup all use this format.
ODI — One Day International
Each team bats for 50 overs (300 balls). Match duration is typically 7 to 8 hours. ODIs offer a deeper range of betting markets including partnership totals, player milestones, and innings runs ranges. The Bangladesh Tigers have historically performed well in ODI cricket, making these fixtures especially popular for bettors in Dhaka and Chittagong.
Test Cricket
The longest and most strategic format — up to five days with no over limit per day. Test matches reward patience and analytical betting. Popular markets include series winner, individual innings totals, and session betting. Bangladesh has been a Test-playing nation since 2000, with home matches at the Sher-e-Bangla National Stadium in Dhaka drawing high bettor interest.
The Hundred
A newer format created by the ECB in England — each team faces 100 balls rather than a set number of overs. Bowlers deliver five or ten consecutive balls per "set". The Hundred is gaining popularity among younger audiences. Betting markets mirror T20, with a focus on boundary counts and top scorer markets.

Smart Play Guide
Bankroll Management
Managing your bankroll well is the foundation of a sustainable and enjoyable gaming experience. Whether you are a casual slot spinner or a serious cricket bettor, these principles apply equally and will help you stay in control of your spending.
This guide is for educational purposes. b399 encourages all players to set personal limits and play responsibly. 18+ only.
Set a Fixed Monthly Gaming Budget
Before you deposit, decide the maximum amount you are comfortable losing in a month. This should be discretionary income — money you do not need for rent, food, or bills. Write this number down and treat it as a hard limit, not a starting point.
Divide Your Bankroll into Sessions
Split your monthly budget into smaller session amounts. For example, if your monthly budget is ৳5,000, consider 10 sessions of ৳500 each. Once a session amount is spent, stop for that session — do not reload mid-session from the next session's allocation.
Follow the 1–5% Per-Bet Rule
Never stake more than 1% to 5% of your total session bankroll on a single bet or spin. If your session bankroll is ৳500, your individual bets should range from ৳5 to ৳25. This keeps you in the game longer and reduces the risk of a single bad outcome wiping out your entire session.
Set a Win Target and Cash Out
Decide before you start that if you reach a certain profit level — say 50% above your session stake — you will stop and withdraw. Locking in profits is a discipline that separates experienced players from those who give back all their winnings chasing even bigger gains.
Stop After a Loss Limit Is Hit
Equally important is knowing when to stop losing. If you lose 50% of your session bankroll, close the game and step away. Chasing losses is the most common cause of problem gambling. A fresh session tomorrow with a clear head is always better than desperate recovery bets today.

Betting & Casino Glossary
New to online betting? This glossary covers the most important terms you will encounter on b399 and across the wider online gaming world.
- RTP (Return to Player)
- The percentage of all wagered money a slot or game returns to players over time. An RTP of 96% means the game pays back ৳96 for every ৳100 wagered, on average, over millions of spins.
- House Edge
- The mathematical advantage the casino holds over players on any given game. A house edge of 2% means the platform retains ৳2 for every ৳100 wagered in the long run. Lower house edge games include Blackjack and Baccarat.
- Wager / Stake
- The amount of money you place on a bet or spin. On b399, the minimum stake on most slots is ৳10 per spin. The stake is deducted from your balance when the bet is confirmed.
- Odds
- A numerical representation of the probability of an outcome and the potential payout. Decimal odds of 2.50 mean a ৳100 bet returns ৳250 in total (৳150 profit) if successful. b399 displays odds in decimal format by default.
- Accumulator / Parlay
- A single bet combining multiple selections. All selections must win for the bet to pay out, but the odds multiply together, creating the potential for large returns from a small stake. Popular for BPL and IPL multi-match betting on b399.
- Live Bet (In-Play)
- A bet placed while a match or game is already in progress. b399 offers live betting on cricket, football, and other sports with real-time odds that change as the match situation evolves.
- Cashout
- A feature that allows you to settle a bet before the event has finished, locking in a partial profit or minimising a loss. b399 offers cashout on selected cricket and sports markets.
- Volatility
- A measure of how often and how much a slot game pays out. High-volatility slots pay large amounts rarely; low-volatility slots pay small amounts frequently. Check the game info panel on b399 to find a slot's volatility rating before playing.
- Free Spin
- A bonus round that lets you spin the reels of a slot game without using your own balance. Free spins are commonly awarded as part of welcome bonuses, in-game scatter triggers, or promotional offers on b399.
- Wagering Requirement
- The number of times you must bet a bonus amount before withdrawing any winnings derived from it. A ৳1,000 bonus with a 20x wagering requirement means you must place ৳20,000 in total bets before requesting a withdrawal.
