In the game you have to catch at least one fish in 30 seconds. If you catch a fish, then the time is updated and you have 30 seconds to catch another fish. In the upper right corner of the screen there is a scale that clearly shows the amount of time left. Next to the scale is a countdown in seconds. You must control the joystick in the lower left corner of the screen and adjust the sight. When you aim, press the "Catch" button. If you miss, you can try again until the time runs out. Sometimes a shark can swim by and eat all the fish, in which case do not miss the opportunity to catch it. Train your reaction in catching fish for a while in the Fishing Fever app.
