slither.io

slither.io, from Lowtech Studios, is an online arcade game in the spirit of the classic snake games, except every other snake on the screen belongs to a real person. The aim is to become the longest snake in the arena.

The rules are short and unforgiving. If a snake's head touches another player's body, it explodes and the run is over. Flip that around, and anyone who crashes into your snake explodes instead, leaving remains that can be eaten to grow longer. That creates the game's key twist: size is not everything. Even a small snake can take down a much larger one by cutting in front of it at the right moment, so clever positioning matters as much as length. Every match is a mix of careful growth and opportunistic ambushes. Because other snakes are controlled by people, no two rounds play out the same way.

The game has 500,000,000+ installs and a 3.9 average from more than 6.5 million ratings, with 60% five stars and 18% one star. The record lists no ads, and there is a single in-app purchase price of $3.99 per item. The most recent update came on 2025-11-09, it runs on Android 5.0 or newer and is rated Everyone. We list 33 versions; the newest, 3.06, is a compact 78.9 MB.

Players who like quick, competitive rounds with simple rules will find it easy to dip into, and it runs on older phones. Those frustrated by sudden losses may find the one-touch-and-you're-out rule harsh.
