About Fish Duel

Fish Duel is an IO game about fish battling beneath the sea. You begin as a small fish, eat food and hunt opponents to evolve and compete for dominance in the ocean.

Eat and evolve

Eating food gives you evolution points (EP). Fill the gauge to level up, then spend EP to upgrade passive skills. You can upgrade skills using hotkeys 1–6 or by clicking the upgrade buttons.

Battle beneath the sea

Swim, eat food and attack other fish as you fight over food in relaxed player-to-player battles. You can consume stamina to accelerate instantly to the highest speed your fish can reach.
