Fishdom: Fish Eat Fish

Fishdom: Fish Eat Fish is an underwater arcade where a small fish tries to become the ocean’s top predator. There’s one rule: eat fish smaller than you and avoid those that are bigger. The more you eat, the faster you grow. You play online matches against other players with timed rounds and boss fights. Each round is limited by a timer: if you survive until time runs out without getting eaten, you win, even if you haven’t reached maximum size. Your fish’s starting weight goes up with every win: the first rounds start at 200, then 250, and so on. The more wins you have, the better your starting position in the next match. You always have a one-second speed boost you can trigger at any time. The game has 3D graphics with detailed underwater locations and many fish types, each with its own behavior and skins.

How to play?

On a computer, use the arrow keys to move and the spacebar to speed up. On mobile devices, move using the virtual joystick. Swim toward smaller fish and eat them to gain mass, and stay away from larger ones. Use the short speed boost carefully to catch prey or escape predators. Survive until the timer hits zero, win round after round, raise your starting weight, and work your way up to the title of King of the Ocean.
