How to play

Slither.io is a snake game played against other people in a shared arena. You steer your snake around that space and grow longer. The developer says you play with millions of players around the world, and the aim is to become the biggest snake of all time. Size is the whole point: the longer your snake gets, the more of the arena you cover and the more carefully you have to watch where your head travels.

Controls explained

Two controls do all the work. You move your snake, and you dash for a burst of speed when you want one. Movement is what you spend most of the round doing, so small corrections usually serve you better than one big swing across the arena. Dash is the extra gear on top of that.

Tips

  • Eat orbs steadily instead of chasing a single far one. Steady growth keeps your line predictable.
  • Save dash for a moment when you need the speed. A fast snake is harder to steer.
  • Watch the snakes around you before you commit to a direction. They are growing at the same time you are.
  • Keep open space nearby so you have somewhere to turn when another snake cuts across your path.
  • Remember that a longer snake is a bigger target. Growth changes how much room you need.
