Shark Attack

Shark Attack is an eat-and-grow ocean arena where you start as the smallest shark in the water and work your way up the food chain. Everything smaller than you is food, everything bigger is a problem, and the whole game is judging which is which fast enough to keep swimming.

How to play: the shark follows your mouse cursor, so steering is just pointing where you want to swim. Hold left click for a short burst of speed to close a gap or escape one. Eating fills a size meter, and each time it fills your shark jumps a tier, which means you can suddenly eat things that were off limits a second earlier. There is no lives system to manage and no loadout, so a lost round costs you nothing but the restart.

Tips worth knowing. Stay near schools of small fish early instead of hunting other players, because ten easy meals get you to the next size tier faster than one risky one. Watch the size of a shape before you commit, since sprinting head first into something one tier above you ends the run instantly. And once you are large, patrol the shallow edges where smaller players farm, rather than cruising the empty middle of the map where there is nothing to eat.

The cartoon art keeps it school friendly, with no blood and nothing gory. If you like it, MOPE io runs the same eat-and-evolve loop on land and water, Animal.io is a straighter animal arena, and Wormeat.IO swaps sharks for worms. Shark Attack plays unblocked in the browser on a school Chromebook.
