Neon Worms

🎮 Touch: left half drags to steer, ⚡ button boosts. Desktop: mouse steers, hold left button or Space to boost. M mutes.

Slither-style arena, single player: outmaneuver 37 AI worms, cut them off, feast on the remains and grow from slug to Neon Python — no waiting rooms, no connection anxiety, instant arena action.

How to play

  1. Steer with the left-half joystick (or your mouse) and glide over glowing orbs to grow longer and thicker.
  2. Cut worms off: if an enemy's head touches your body, it bursts into high-value orbs — boost (hold to burn length) to steal the feast first.
  3. The arena is a 4000×4000 neon grid with a deadly pink border; every AI worm hunts, flees and avoids bodies like a real rival.
  4. Grow from Slug to Neon Python on the seven-tier rank ladder; the Daily Arena seeds one food map for the whole world each UTC day.

Frequently asked questions

Is this slither.io offline?

It is a slither-style arena played entirely against AI worms — no servers, no matchmaking and no connection needed once the page loads. The official game advertises an AI mode too; this is that idea as a free browser original with neon visuals.

How do I kill other worms?

You never touch them to win — you position your body so their head crashes into it. Cut across a worm's path, let it chase you in a loop, or boost to intercept; any head-to-body contact bursts the attacker into orbs worth double points.

What does boosting do?

Holding boost (⚡ button, left mouse or Space) raises your speed 1.8× and burns two body segments per second, dropping them as orbs behind you. Below 12 segments the boost cuts out so you can never shrink to zero by accident.

Does it work on mobile?

Yes — the left half of the screen is a virtual joystick that steers wherever you drag, and the boost button is sized for thumbs. The camera zooms out as you grow so long worms stay manageable on a phone.
