Shark Attack.io

Shark Attack.io is a free-for-all ocean arena where size rules everything. Start small, feed on plankton and lesser fish, then hunt players once you outmass them.

Speed and reflexes matter as much as growth — bigger sharks still die if they chase the wrong fight. Read the water, cut off smaller targets, and avoid becoming someone else's meal.

Classic agar-style tension meets underwater predators in a simple loop: eat, grow, dominate — or get eaten.
