About Slither.io

Slither.io is a all-time favourite that needs no tutorial: the whole appeal fits in one sentence, and the mastery curve takes care of the rest. A fixture of every serious unblocked list for years, now living on a page built to stay up.

This is Slither.io's info page on the main game grid. We're looking for an authorized, working source; until one passes a real play-test, the page stays honest and points you at games that do play here. Finished this one? Basketball Stars is next on the same shelf.

Slither.io Controls

Controls: Use the MOUSE to steer your snake around the arena and click or hold to boost. Eat glowing orbs to grow longer. Avoid crashing headfirst into other snakes. Cut off rivals to make them crash into you, then eat their remains. Become the biggest snake on the server.

Keep these for when the game returns — or try a similar game below; most share the same control scheme.

Tips for Slither.io

  • Lag is usually your tabs, not the game: close the streaming ones and HTML5 flies on any Chromebook.
  • Improvement happens between sessions, not during them — three short visits beat one long grind.
  • In anything with upgrades, buy consistency before power: the boring stat is usually the broken one.
