Worm Arena

Worm Arena is a multiplayer-style arena you play on your own against bots. You steer one glowing worm with the pointer, it never stops, and every light orb it swallows makes it a little longer and a little thicker. There is one rule and it cuts both ways: a worm dies the moment its head touches another worm's body. Ram your head into someone and you are finished. Slide your length across their path and they are the one bursting into a feast of orbs for everyone nearby.

Boost when you need to close a gap or get out of one. Boosting spends your own length and drips it behind you as orbs, so a long chase costs real size and lights a trail for whoever is following. The rivals are not all the same. Rookies wander into trouble and into you, regulars farm quietly and make the occasional silly mistake, sharks cut across your path the second you drift too close, and the biggest worms curl into slow circles to trap anything smaller. The edge of the arena is a bright ring that kills on contact, so the minimap in the corner is worth a glance.

The board on the right stays live: a top ten, your rank out of everyone in the arena, and a feed of who just ate whom. Rivals join and leave the way they do in any busy arena, the ones that die are back in seconds, and the count drifts between the mid twenties and the high thirties. Pick a name and a skin on the way in, fire one of four emotes with the number keys, and when you are finally eaten the card shows your length, your rank and how long you lasted. Rounds are quick, your best length and best rank are kept on your own device, and a new high score is usually one more run away. It plays in the browser on a desktop and on a phone in portrait, with a virtual joystick and a boost button.
