slither.io is a free multi-platform game, controlled entirely with the mouse or touch screen, in which you play as a brightly-coloured snake in a vast, featureless land full of dots. You collect and eat these dots to grow larger, but there's a catch: other snakes, controlled by other players just like you, can and very well might ed you. You're made up of a lot of dots, too...

You Can Play Naughty, Or Play Nice

The mechanics of slither.io are very simple. As you grow in length by picking up dots, you grow in size. If you run into your own body or another snake's body with your head, you die, starting anew, and turn into a bunch of very valuable dots. You can spend your current size to speed up, too.

A Fun Diversion

There's really not a lot of depth to slither.io, but that shallowness is also one of its better elements. You can get to the top of the scoreboard just by playing for a day, and no one can stay there forever -- there's no saving your progress, after all. The game is reasonably well-balanced, though frustrating at times. Occasional rude names aside, it's very family-friendly, too.
