Betting Exchange — What Are Back and Lay?
A betting exchange is completely different from a traditional sportsbook. Find out how it works here.
How Does the Exchange Work?
In a traditional sportsbook you always bet against the bookmaker. In a betting exchange you bet directly against other players — the platform only takes a small commission.
The odds are set not by the platform but by the players participating in the market. This generally means better odds.
Example (Bangladesh vs India)
Back Bet: You think Bangladesh will win. If you place a ৳500 Back bet and win, you receive ৳750 (odds 1.5).
Lay Bet: You think Bangladesh will not win. If you Lay ৳500 against another player's Back bet and Bangladesh loses, you profit ৳500.
Back vs Lay Comparison
| Aspect | Back Bet | Lay Bet |
|---|---|---|
| Meaning | Predicting that something will happen | Predicting that something will not happen |
| Condition to Win | If your prediction is correct | If your prediction is wrong |
| Risk | The amount staked | Liability |
| Who Can Place It | Any player | Any player |
| Odds setting | Market participants | |
A small commission applies on each winning bet in the exchange. This is displayed transparently.

Wagering requirement = (deposit + bonus) × specified multiplier. See the Terms & Conditions page for full details.
Fishing & Arcade Games
Shooting game fun and jackpot thrills all in one.
In fishing games you hunt sea creatures using a cannon. Each shot costs a certain number of points or bet amount, so smart players manage their cannon level carefully.
Small fish give lower rewards but appear more frequently. Catching big boss fish like the boss characters in Mega Fishing or Ocean King Jackpot gives large multipliers — but requires more shots.
Fishing Games
Choose your cannon level, hunt fish, and collect points.
Shooter Arcade
Quick reflexes needed — stay on target and rack up big scores.
Dice Arcade
Simple rules, fast rounds — ideal for beginners.
Bombing Fishing
Hunt multiple fish at once with bombs — an exciting mode.
Shot Cost Management Tips
- Always start with a low cannon level — get a feel for the environment
- Raise the cannon level for big boss fish, lower it for small fish
- Set a shot cost limit for each session
- When a jackpot boss spawns, attack together as a group
- If there are too many fish on screen, wait a moment — a better opportunity will come
- If a losing streak starts, stop the session and take a break
Always remember: in games like Bombing Fishing and Jackpot Fishing, keep the cost of each shot within your overall budget.
Bankroll Management Guide
Play responsibly — it is the key to long-term enjoyment.
1. Set a gambling budget
First, set a monthly budget for yourself — an amount whose loss would not affect your daily life. Never exceed this budget. Gambling is for entertainment, not as a source of income.
2. Divide into sessions
Split your total budget into smaller sessions. For example, divide a monthly budget of ৳5,000 into ৳1,250 per week and ৳400–500 per session. This reduces the risk of losing everything in one sitting.
3. The 1–5% rule per bet
Keep each individual bet between 1% and a maximum of 5% of your total session balance. This rule protects you from a bad streak and gives you the chance to play more rounds.
4. Know when to stop after a win
Set a target after a big win. For example, if your session balance doubles, set aside half and continue playing with the other half. This keeps your profit safe.
5. Stick to your loss limit and stop
End the session once you have lost 50% of your session balance. Placing more bets to recover lost money usually results in even greater losses. Take a break for the day.
6. Track your play history
Keep a record of your deposits, withdrawals, and balance every week. This helps you understand your own playing patterns and make responsible decisions. Your complete transaction history is available on the 558h66 account page.
