Create an Account NowCricket Format Explained
Cricket has three main international formats, each with its own characteristics and betting markets.
| Format | Overs | Duration |
|---|---|---|
| T20 (T20) | 20 overs | About 3 hours |
| ODI (One-Day) | 50 overs | About 7–8 hours |
| Test (Test) | Unlimited | Up to 5 days |
| The Hundred | 100 balls | About 2.5 hours |
T20: The fastest and most popular format. BPL, IPL, BBL and PSL are all played in this format. Betting markets change after every over — ideal for in-play betting.
ODI: Being a longer match, more markets are available — top batsman, highest wicket-taker, total match runs, and more.
Test: This format lasts up to five days and allows innings-based betting. Best suited for strategic bettors.
Football betting
Football fans in Bangladesh follow the world's top leagues closely. bt399 offers betting on the Premier League, La Liga, UEFA Champions League and FIFA World Cup qualifiers.
Popular betting markets
- 1X2: Pick one of three outcomes — the home team wins, a draw, or the away team wins.
- Double Chance: Pick two of three possible outcomes — lower risk.
- Over/Under Goals: Bet on whether the total number of goals will be above or below a set number.
- Both Teams to Score: Bet on whether both teams will score in the match — a straightforward market.
- Asian Handicap: The weaker team is given a goal advantage to level the market.
- First Goalscorer: Bet on which player will score the first goal.
Major Champions League and Premier League matches often kick off at midnight Bangladesh time or later — which is where the live betting feature becomes especially useful.
RTP and house edge explained
RTP, or Return to Player, is a percentage that shows how much a game returns on average per ৳100 wagered over the long term. For example, if a game has an RTP of 96%, it returns an average of ৳96 for every ৳100 bet — the remaining ৳4 is the casino's commission. This figure is based on millions of spins, so it does not apply to a single or even ten spins.
House edge is the flip side of RTP — a 96% RTP means a 4% house edge. Different games have different house edges. Slot game RTP typically ranges from 92% to 98%. Playing Blackjack with the correct strategy can push the RTP close to 99%. European Roulette generally has an RTP of 94% to 97%.
Volatility is another important factor. High-volatility games can deliver big wins but also long stretches without winning. Low-volatility games pay out smaller amounts more frequently. Choosing a game that matches your bankroll and patience level is the smart approach.
Knowing this information before you play at bt399 helps you make more informed decisions. Remember, gaming is a form of entertainment — RTP is a statistical average, and the outcome of each round is completely random.
How to read odds
Decimal Odds
Most Asian sites, including bt399, use decimal odds. Example: a ৳500 bet at odds of 1.80 returns a total of ৳900 (৳500 × 1.80), meaning a profit of ৳400. The calculation is simple — just multiply your stake by the odds.
Implied Probability
Odds tell you how likely the bookmaker thinks an outcome is. Odds of 1.80 mean 1 ÷ 1.80 = roughly 55.6% probability. If you think the real probability is higher, that represents a good betting opportunity.
Comparing other formats
Fractional odds (e.g. 4/5) are used in the British market — a ৳5 bet returns ৳4 profit, so ৳9 in total. With American moneyline odds, a positive figure (+180) means ৳180 profit on a ৳100 bet; a negative figure (-150) means a ৳180 bet returns ৳100 profit.
24/7 support in Bengali
