Cricket Format Explained
Understanding the different cricket formats makes betting markets easier to follow. Here are the key differences between each format.
🏏 T20
20 overs per innings. Matches usually finish in 3–4 hours. Toss, first wicket, powerplay runs, and most sixes are popular betting markets. BPL and IPL are played in this format.
🏟️ ODI (One-Day)
50 overs per innings. Matches run for 7–8 hours. In-play betting at the mid-game stage offers many more opportunities. The ICC Cricket World Cup is played in this format.
📋 Test
A five-day match with two innings per team. Matches can end in a draw. Day-by-day run totals, series results, and pitch condition markets add a different kind of enjoyment to betting.
💯 The Hundred
Just 100 balls per innings. In this newer format from England, each set consists of 10 balls. The fast-paced game creates new betting markets.
Popular Leagues
BPL (Bangladesh Premier League) — Bangladesh's most exciting T20 tournament. IPL (Indian Premier League) — India's mega T20 league. BBL (Big Bash League) — Australia's summer T20. PSL (Pakistan Super League) — Pakistan's T20 league. You can bet on all these leagues at a770.
Local Card Games
Popular card games from Asian tradition are now available in the a770 casino
Teen Patti
In this game played with three cards, the strongest hand wins. Each round, you can either "pack" or raise the bet.
Starter tip: Begin with small bets and learn by watching how others play.
Live DealerAndar Bahar
The dealer places one card in the middle and deals to either the "Andar" or "Bahar" side. You have to choose which side will match — the odds are roughly 50–50.
Starter tip: Stick to one side consistently and stay away from side bets.
Live DealerCallbreak
In this four-player trick-taking game, spades are always trump. Before each round, you bid on how many tricks you will take.
Starter tip: Before placing a high bid, make sure you have spade cards in your hand.
Against Other PlayersLudo / Rummy
In the familiar Ludo, roll the dice to move your pieces and knock out opponents. In Rummy, you need to match cards to form sets or sequences.
Starter tip: In Rummy, form a pure sequence quickly — it's the foundation of winning.
Against Other PlayersBonus Terms & Conditions in Plain Language
It's important to understand the terms before claiming a bonus. Here are the key points explained clearly.
| Bonus Type | Amount | Wagering |
|---|---|---|
| Welcome Bonus (First Deposit) | 150%, up to ৳20,000 | 10x the bonus amount |
| VIP Weekly Cashback | Bronze 0.3% — Diamond 1.5% | No wagering |
Working Example
If you deposit ৳1,000, you will receive a ৳1,500 bonus — giving you a total balance of ৳2,500. To withdraw the bonus, you only need to wager the bonus amount: ৳1,500 × 10 = ৳15,000. The deposit amount is not counted in this calculation.
Key Terms Explained
Wagering Requirement
You must place a set amount in bets before withdrawing the bonus money. You cannot withdraw the bonus portion until this condition is met.
Game Contribution
Not all games contribute equally to wagering calculations. Slots generally contribute more and card games may contribute less — check the terms and conditions.
Maximum Bet Limit
While a bonus is active, there is a maximum limit per bet. Exceeding this limit may result in the bonus being cancelled.
Bonus Expiry and Maximum Cash-Out
Each bonus has a set expiry period. There may also be a limit on how much you can withdraw from a bonus — see the offer page for details.
How to Read Odds
The first step to success in betting is understanding odds. Here are the three main formats explained clearly.
Decimal Odds
This is the simplest format. Multiply your stake by the odds to get your total return.
Implied Probability
Odds give you an easy way to understand how likely the bookmaker thinks an event is. Odds of 1.80 mean the bookmaker considers the probability of the event to be around 55–56%.
Fractional Odds
For example, 4/5 means ৳4 profit on a ৳5 stake. This is commonly used in the British system.
American Odds (Moneyline)
+180 means ৳180 profit on a ৳100 stake. -150 means a ৳150 stake returns ৳100 profit.
