Bankroll Management

Each shot costs money. Start with lower weapon settings to build your balance, and only increase your bet when a high-value Boss enters the screen.

Utilize Special Weapons

Watch for special items like bombs or electric nets. Triggering these at the right time can clear the entire screen, leading to a massive windfall of coins.

Timing is Everything

Pay attention to the fish movement patterns. Wait for high-value targets to be clear of smaller fish so your bullets reach the intended target without obstruction.
