Activate BonusCricket Betting Markets
From the Bangladesh national team — the Tigers — to BPL, IPL and the T20 World Cup, bk688 offers betting on every major tournament. Below are seven common betting markets explained in plain language.
Match Winner
Predict which of the two teams will win. Example: Bangladesh vs India — pick Bangladesh.
Toss Winner
Which team will win the toss before the match starts. Example: India could win the toss, odds 1.95.
Top Batsman
Who will score the most runs in their team. Example: Shakib Al Hasan could be the top scorer.
Total Runs Over/Under
Whether total runs in the full innings will be above or below a set line. Example: Over bet on a line of 320 runs.
Runs in an Over
How many total runs will be scored in a specific over. Example: 12+ runs in the 15th over.
Method of Dismissal
How the next wicket will fall — caught, bowled or run out. Example: the next wicket will be bowled.
Player of the Match
Who will deliver the best performance in the match. Example: Mustafizur Rahman as Man of the Match.
During a match, a team's odds shift quickly with every wicket that falls. If the bowling side builds pressure toward the end of an over, the batting side's odds drop. In-play betting creates opportunities at every moment.

Fishing and Arcade Games
Fish-shooting games are very popular in Bangladesh. bk688 offers several titles from JILI, including Mega Fishing, Happy Fishing and Ocean King Jackpot.
How Does It Work?
In each game, fish of various colours swim across the screen. You shoot at them with a cannon — small fish give fewer points, while big fish or boss fish give large multipliers.
Cannon Level: Using more shots deals more damage and increases the chance of catching fish. On a smaller budget, it is better not to chase big fish with a small cannon.
Boss Fish: Some games feature special boss fish that appear occasionally — a single well-timed shot can be very effective. Many players team up to take down boss fish together.
Budget Management: Set a cost per shot and decide in advance the maximum you will spend in a session.
Arcade Game Types
- Crane Game — control a machine to aim at targets and win prizes
- Dinosaur Adventure — mission-based shooting format
- Boom Legend — explosion-based multiplayer table
- Coin Pusher style game — drop coins to grab big prizes

How to read odds
Understanding odds is essential in online betting. bk688 uses the decimal format — it is easy to understand.
Decimal Odds
If the odds are 1.80 and you bet ৳500:
৳500 × 1.80 = ৳900 returned (profit ৳400)
The higher the odds, the lower the chance of winning — but the bigger the reward.
Implied Probability
To find the winning probability from odds: 1 ÷ odds × 100
Example: at odds of 1.80, probability = 1 ÷ 1.80 × 100 = 55.6%
Comparison with other formats
| Format | Example | Meaning |
|---|---|---|
| Decimal | 1.80 | ৳0.80 profit per ৳1 |
| Fractional | 4/5 | ৳4 profit for every ৳5 staked |
| American | -125 | ৳100 profit for every ৳125 staked |
Bankroll management guide
Smart betting is not just about winning — it is also about managing your spending wisely. The tips below will give you a more enjoyable experience in the long run.
Set a budget
Decide in advance how much you can spend on entertainment each month. This amount should only come from your spare money — not from funds set aside for essential needs.
Divide into sessions
Split your monthly budget into several equal sessions. Rather than spending the entire budget in one session, set a fixed amount for each day.
Follow the 1–5% rule
Keep each bet to a maximum of 1 to 5 percent of your total bankroll. This reduces the risk of losses and allows you to play for longer.
Stop after winning
Stop playing once you reach a set winning target. Avoid the urge to place bigger bets while on a winning streak — withdraw your winnings.
Stop at your loss limit
Stop playing once you have lost a set amount in a session. Placing larger bets to recover losses risks making the situation worse.
