Expert Winning Tips

Master the Lock-On

Don't waste ammo on crowded schools. Use the lock-on feature to target specific high-value bosses. This ensures every bullet hits the target, maximizing your potential return on investment.

Budget Your Ammo

In Undersea Killer, your bullets are your balance. Avoid continuous rapid fire unless a boss is on screen. Strategic, well-timed shots on mid-sized fish often yield the most consistent profits.

Trigger Boss Events

Keep an eye out for the Golden Dragon or Kraken. These events offer massive multipliers. When these appear, increase your bet size slightly to take full advantage of the high-payout window.

Utilize Power-ups

Collect special drops like Frozen Bombs or Electric Nets. These free power-ups can clear the screen and provide huge payouts without consuming your PHP balance.
