Slither — Play Online Free

4.4(40,324 ratings)·2M plays·arcade

Slither is the viral .io snake game you can play online for free, right in your browser. Steer with your mouse or finger, eat glowing orbs to grow longer, and force rival snakes to crash into your body — when they do, they burst into a feast of orbs for you to swallow. The bigger you grow the higher you climb the leaderboard, but long snakes turn slowly and make bigger targets. No download, no signup, no install — works on phone, tablet and computer.

Controls

Move your mouse or finger to steer your snake. Eat the glowing orbs to grow. Boost for a burst of speed. Never let your head touch another snake — make them hit you instead.

Tips & Strategy

  • Eat the big glowing orbs left behind when a snake dies — one dead rival can double your length in seconds.
  • Cut in front of a bigger snake's head with a sharp turn so it crashes into your body. Their whole length becomes orbs for you.
  • Don't chase kills near the world border — pinning yourself against the edge is how most runs end.
  • Long snakes turn slowly. The bigger you get, the earlier you must plan your turns and circles.
  • Coil into a tight loop to trap a smaller snake inside, then close the circle so they have nowhere to go.
  • Stay near the centre of the map early — the edges are where snakes get cornered and killed.

Slither — Play the Classic .io Snake Game Online Free

Slither is the snake game that took the world by storm — and you can play it online free, right here, with nothing to download. Steer your snake with your mouse or finger, swallow the glowing orbs scattered across the map to grow longer, and outmaneuver dozens of rival snakes all fighting for the same food.

The rule is brutally simple: if your head touches another snake, you die. If their head touches your body, they die. Everything else is strategy.

How to play Slither

  • Steer by moving your mouse (computer) or dragging your finger (phone). Your snake always follows the cursor.
  • Eat orbs to grow. The longer you are, the higher you rank — but the slower you turn.
  • Boost for a short burst of speed to escape a trap or cut off a rival (you'll shed a little length while boosting).
  • Survive. Last snake slithering, or biggest on the board, wins.

The killer move: make them crash into you

You never win by ramming other snakes head-first — that kills you. Instead you win by cutting them off. Swing in front of a rival's head with a sharp turn so their head slams into the side of your body. The instant they crash, their entire length explodes into a glowing trail of orbs — and you're right there to swallow all of it.

This is how small snakes take down giants. A well-timed cut-off in front of the #1 snake can hand you hundreds of orbs and rocket you up the leaderboard.

Strategy tips to top the leaderboard

  1. Feast on the dead. The orbs from a killed snake are worth far more than the tiny ones scattered around. Always swing back to clean up a kill.
  2. Coil and trap. Wrap a tight circle around a smaller snake and slowly close it — they'll have nowhere to turn.
  3. Respect the border. The edge of the map is a death trap. Never let a fight push you into the wall.
  4. Plan turns early. Big snakes are sluggish. The bigger you grow, the further ahead you must steer.
