Fishing & Arcade Games
JACKPOT FISHING
Shoot, fish, and win big prizes
How do fish shooting games work?
In fishing games, you shoot fish using a cannon. Each shot has a set cost, and different fish carry different multipliers. Small fish are easy to kill but give smaller rewards; big boss fish are harder to kill but offer huge rewards.
Cannon Level
Raising the cannon level increases the cost per shot but also improves your chances of taking down bigger fish.
Boss Fish
Rare boss fish carry the biggest rewards. Team shooting makes them easier to take down.
Budget Management
Always start at a low cannon level and increase gradually. Stay aware of how much each shot costs.
Arcade Game Types
Color Game, Ludo Quick, Callbreak Quick — fast-paced familiar games with a fresh twist.

RTP and House Edge Explained
What is RTP (Return to Player)?
RTP stands for "Return to Player" — the rate at which money is returned to players. If a game has an RTP of 95%, it means that theoretically, for every ৳100 wagered, players receive back an average of ৳95. This figure is calculated over billions of game sessions — the result of a single session can be completely different.
Typical RTP ranges by game type: slot games generally fall between 92%–98%; blackjack can offer an RTP of up to around 99% when played with the correct strategy; European roulette typically falls between 94%–97%.
What is House Edge?
House edge is the flip side of RTP. If the RTP is 96%, the house edge is 4%. This means the casino keeps an average of ৳4 for every ৳100 wagered. It is the foundation of a casino's business model.
Why does this information matter? Knowing the RTP and house edge before you play allows you to make informed decisions. Choosing higher RTP games means getting more value for your money over the long run. Keep in mind, however, that every spin or round is completely independent and RTP is not a guarantee of winning.
Account Verification Process
KYC (Know Your Customer) verification is an important part of every trusted casino platform. It keeps your account secure and helps prevent fraud.
National ID Card
Upload clear photos of both sides of your National ID Card (NID) or passport.
Proof of Address
Verify your current address using a utility bill, bank statement, or government document.
Selfie Verification
Take a selfie holding your National ID Card — this confirms your identity.
Approval
Verification is usually completed within 1–24 hours. Once approved, full withdrawal access is activated.
Why is KYC required?
- Keeps your account secure
- Prevents money laundering
- Blocks access by minors
- Ensures faster withdrawals
- Ensures fair play
