About Worm Arena

Worm Arena is a slither-style .io game. Steer your worm with the mouse, eat the glowing dots to grow and climb the live leaderboard.

The trick is to make other worms run into your body — when they crash they burst into a pile of food. Boost to cut them off, but boosting costs length.

How to play Worm Arena

Your worm follows the mouse or your finger. Hold the mouse button or Space to boost. Never let your head touch another worm.
