Our take

There’s something to be said for a formula this simple staying popular for as long as it has. That said, half a billion installs and a 3.9 rating tell you people keep downloading it out of habit more than genuine enthusiasm for its current state.

About slither.io

Play against other people online! Can you become the longest slither?

If your head touches another player, you will explode and then it’s game over. But if others run into YOU, then THEY will explode, and you can eat their remains!

In slither.io, you have a chance to win even if you’re tiny. You can swerve in front of a much larger player to defeat them, no matter how big you are!

Download now and start slithering! Good luck!

What we like

  • Simple, instantly-understandable core loop: grow, cut off rivals, survive
  • Genuine online multiplayer tension since real players can end your run any second
  • Massive install base built almost entirely on word of mouth

Watch out for

  • Visual and UI presentation hasn't meaningfully evolved since its original release
  • Sub-4 rating reflects years of ad load and server lag complaints piling up
Verdict: The original .io hit still works as a quick multiplayer fix, but it shows its age next to the clones it inspired.
