How to Play Fishing and Arcade Games?
Fishing games are shooting-style games where you shoot fish moving across the screen to win points or cash prizes. Each fish has its own multiplier — smaller fish give smaller rewards, while big boss fish give much larger ones.
Cannon Level: Controls the power of your shots. Higher power means more cost per shot, but a better chance of catching big fish. Practice at a lower level when starting out.
Boss Fish: Large boss fish occasionally appear on screen and are difficult to defeat alone. Attacking them as a group can win big rewards. Keep track of your cost per shot to stay within your budget.
Popular Arcade Game Types
- Multiplayer Fishing — multiple players hunt fish together
- Bombing Fishing — use explosives to catch multiple fish at once
- Jackpot Fishing — catch a special golden fish to win the jackpot prize
- Dragon Fortune — an exciting dragon-themed shooting game

RTP and House Edge Explained
RTP (Return to Player) is the percentage of total bets returned to players over the long term in a game. For example, a 96% RTP means an average of ৳96 is returned for every ৳100 wagered — but this is an average over millions of rounds, not a single session.
Typical RTP ranges across different games: slot games 92–98%, blackjack around 99%, roulette 94–97%. A higher RTP means a lower house edge — more favorable for the player.
House Edge is the casino's mathematical advantage. It is the complement of RTP — if RTP is 96%, the house edge is 4%. This means the casino retains 4% of total bets over the long term.
Volatility refers to how frequently and how large rewards are paid out. High-volatility games pay larger rewards less often; low-volatility games pay smaller rewards more frequently. Understanding these facts before playing is the first step toward responsible gaming.
Account Verification Process
KYC (Know Your Customer) verification ensures the security of your account and guarantees fair service.
Why is it needed?
KYC is mandatory to prevent money laundering, stop fraud, and confirm the player's identity.
Required Documents
A National ID card (NID), proof of address, and a selfie photo are generally required.
Processing Time
Verification is usually completed within 1–24 hours. It may take a little longer during busy periods.
After Verification
Verified accounts unlock higher withdrawal limits, faster payments, and VIP benefits.
