Fishing & Arcade Games
Fishing games are a unique type of arcade-style game where you use a cannon to catch fish. Each fish has a different value — smaller fish carry lower multipliers, while large "boss fish" offer bigger rewards.
Popular Fishing Game Types
- Multiplayer Fishing: Multiple players play together — JILI's Mega Fishing is one such game.
- Boss Fish Stage: After a set time, a massive boss fish appears — catch it and you win a big reward.
- Jackpot Fishing: During a random jackpot event, catching a special fish earns an extra bonus.
- Arcade Racing / Shooting: Beyond fishing, a variety of interactive arcade-style games are also available.
💡 Tips for Managing Cannon Cost
The higher the cannon power, the more each shot costs. Always start on low power and increase the cannon level in line with your balance. You can raise the power during boss fish stages.
RTP and House Edge Explained
RTP, or Return to Player, is a long-term statistic for a game that shows what percentage of total bets is returned to players. For example, if a game has an RTP of 96%, on average ৳96 out of every ৳100 wagered is returned to players — though this is not guaranteed in any single session, it is the average across millions of spins.
The RTP range varies by game type. Slot games generally have an RTP of 92–98%; blackjack can reach nearly 99% with correct strategy; roulette typically has an RTP of 94–97%.
House edge is the flip side of RTP — it is the percentage the casino keeps on average from every bet. A 96% RTP means a 4% house edge. The lower this number, the better it is for the player.
Knowing the RTP before choosing a game helps you make informed decisions. High-volatility slots offer the chance of bigger rewards but wins come less frequently; low-volatility slots pay out smaller rewards more often. Choose a game that matches your budget and preference.
Betting Glossary
A simple explanation of key betting and casino terms for new players.
RTP (Return to Player)
A statistic showing what percentage of total bets a game returns to players over the long term. A higher RTP is more favorable for the player.
House Edge
A measure of what percentage the casino keeps on average from every bet. Subtract the RTP from 100% to get the house edge.
Wager / Wagering Requirement
The condition that determines how many times you must wager bonus funds before withdrawing them. For example, 10x means you must place a total of ৳10,000 in bets for a ৳1,000 bonus.
Stake
The amount of money you put at risk in a specific bet or game round. Always set your stake within your means.
Odds
A numerical expression of the probability of an event occurring. Higher odds mean a bigger reward but a lower chance of winning.
Parlay / Accumulator
Combining multiple bets together, where winning each one multiplies the total reward. If one bet loses, the entire wager is lost.
Live Bet
A bet placed in real time while a match or game is in progress. Odds change every moment, so the ability to make quick decisions is essential.
Cashout
The option to withdraw a set amount for a guaranteed return while a bet is still in play. In Aviator, cashing out before the crash is the core strategy.
Bankroll
The total amount of money set aside specifically for gaming. Proper bankroll management is the key to playing sustainably over the long term.
Volatility
The balance between how often you win and the size of rewards in a game. High volatility = less frequent but larger wins; low volatility = frequent but smaller wins.
Free Spin
Extra spins in a slot game at no cost, typically triggered by scatter symbols or given as a bonus.
Spread
A betting market based on predicting the margin between two teams. Spread betting is mainly used for differences in cricket runs or number of wickets.
Account Verification Process
KYC verification is required for security and legal compliance. It keeps your account and funds protected.
Why Is KYC Required?
KYC verification is mandatory under international security standards and to prevent money laundering. It protects your account from unauthorized access.
Required Documents
You will need to upload a clear photo of your National ID (NID) or passport, proof of address, and a selfie for verification.
Processing Time
Verification is usually completed within 1–24 hours. Once successful, you will receive a notification by email or on the platform.
What Happens After Verification?
Once verification is complete, you gain full withdrawal access, higher transaction limits, and eligibility to join the VIP program.
