Remember your own ammunition
If you are a regular player, we would recommend that you choose to shoot small fish, unless you have a lot of money in your account, because you have to remember that shooting big fish means that you need to sacrifice a lot of bullets.
Calculation of firing angle
In the process of shooting fish, if the bullet does not hit the fish immediately on the screen and touches the window, the bullet will bounce until it hits the fish, so you can also use this to shoot easier fish species.
Try to give up hidden fish
In the game, you will often find fish hidden under rocks or seaweed. These fish usually have higher bonuses, but because of their hiding and avoidance, players may waste a lot of bullets to shoot.
Use a different gun
You can switch between weapons of different strengths. Although the cost of a strong bullet will be higher, a powerful weapon is more likely to take out a tough fish.
