Bankroll Management Guide
Playing responsibly is not just about thinking of winning — it is about managing your budget wisely. Follow the guide below.
Decide in advance how much you will spend on gaming each week or month. This amount should only be money that, if lost, will not affect your daily life.
Divide your total budget into smaller sessions. For example, a weekly budget of ৳2,000 split into 5 sessions gives you ৳400 per session.
Place a maximum of 1 to 5 percent of your total bankroll on each bet. This ensures you can keep playing over the long term.
After a big win, set a target and take a break once you reach it. Making decisions at the moment of a win is often the most profitable choice.
If you lose 50% of your session budget, stop playing for the day. Placing more bets to recover lost money is a dangerous habit.
Fishing and Arcade Games
Fishing games are a unique type of game where you use a cannon to catch fish and earn rewards based on the value of each fish.
Cannon Levels and Fish Multipliers
Increasing the cannon's power raises your chances of catching bigger fish, but also increases the cost of each shot. Use smaller fish to fire more shots at a lower cost.
Boss Fish and Special Rewards
Each round features a special boss fish with a much higher multiplier than regular fish. Hunting in a group increases your chances of winning.
Arcade Shooting Games
Play in classic shooting style — pick your target, shoot at the right moment, and unlock bonus rounds.
Shot Cost Management
Every shot costs money, so think it through before going after the big fish. Keep your bet size within your means.
Account Verification Process
KYC (Know Your Customer) verification secures your account and opens the door to faster withdrawals. It is a one-time process.
Why is KYC required?
KYC is an international standard for financial security and identity protection. It prevents fraud and money laundering, and keeps your account safe.
What documents are needed?
Upload photos of both sides of your National ID (NID) or passport, proof of address, and a selfie.
Processing Time
Verification is usually completed within 1 to 24 hours. You will be notified by email or live chat once approved.
What happens after verification?
After full verification you can make unlimited withdrawals and gain access to premium promo offers.

Betting Terminology
Simple explanations of common betting and casino terms for new players.
RTP (Return to Player)
The theoretical rate at which a game returns a percentage of total bets to players over the long term. It is not a guarantee of individual winnings.
House Edge
The mathematical advantage a casino holds over the long term in every game is called the House Edge. It is the inverse of RTP.
Wager / Stake
The amount of money you put at risk in each bet is called a Wager or Stake. Wagering Requirement refers to how many times you must bet before you can withdraw a bonus.
Odds
A numerical expression of the probability of an event occurring. In betting, the higher the odds, the greater the potential winnings but the lower the probability of the event happening.
Parlay / Accumulator
Combining multiple bets together. If all selections are correct you win big, but if any one of them is wrong you lose the entire bet.
Live Bet
The ability to place bets in real time while a match or game is in progress. Odds change continuously based on how the match unfolds.
Cashout
The ability to close a bet and take a partial profit before the match ends. Useful for reducing risk and securing a guaranteed return.
Volatility
The measure of how frequently and how large wins appear in a slot game. High-volatility games pay out big wins less often; low-volatility games pay out smaller wins more frequently.
Free Spin
The chance to spin a slot game for free. Usually given as a bonus feature or promo and may come with special multipliers.
Bankroll
The total amount of money set aside for gambling. Proper bankroll management helps ensure you can keep playing over the long term.
Spread

The number of times you must use a bonus amount as a bet in order to withdraw it. Example: 20x means a ৳100 bonus requires ৳2,000 in bets.
