Fishing and Arcade Games
In fishing games, you control a cannon and hunt fish underwater. Each fish has its own multiplier — small fish are easier but pay less, while boss fish take more ammunition to catch but offer bigger rewards.
Mega Fishing
Multiple players at once, with massive boss fish and bonus rounds.
Bombing Fishing
Use explosive weapons to catch many fish at the same time.
Ocean King Jackpot
A special fishing tournament with a progressive jackpot.
Dinosaur Tycoon
A prehistoric arcade — target massive dinosaurs for big rewards.
Tips: The cost of each shot may vary. Increasing the cannon level makes shots more powerful but also raises the cost per shot. New players should start at a lower level to manage their bankroll.

RTP & House Edge Explained
RTP, or Return to Player, is the percentage of total bets in a game that is returned to players over the long run. For example, if a slot game has an RTP of 96%, it means an average of ৳96 comes back for every ৳100 wagered — but this is an average across millions of spins, not a guarantee for any individual session.
RTP typically varies across different game categories. Slot games generally have an RTP in the range of 92%–98%. Skill-based card games like blackjack can have a relatively higher RTP, since applying the right strategy can reduce the house advantage. For roulette, the European version sits in the 94%–97% range.
House edge is the flip side of RTP — the portion the casino keeps for itself over the long run. If the RTP is 96%, the house edge is 4%. The lower the house edge, the better it is for the player. Keep in mind, though, that RTP gives no meaningful prediction for short-term sessions — it is a long-term statistical figure only.
A game's volatility, or variance, also matters. In high-volatility games, big wins come less frequently but are larger in size. In low-volatility games, smaller wins come more often. It is wise to choose a game that matches your budget and risk tolerance.

Odds
A numerical expression of the probability of an event, which determines how many times your stake is returned to you. Higher odds mean more risk but a higher reward.
Parlay / Accumulator

Wagering Requirement
The condition specifying how many total times you must wager bonus funds or winnings before you can withdraw them. For example, 25x means you must bet 25 times the bonus amount.
