How to Play Slither io Online
The goal is to become the longest worm on the map. Steer around to collect glowing orbs and grow, but never let your head touch another worm that’s instant game over. The winning move is to cut in front of larger players so they crash into your body, then feast on the orbs they leave behind for a massive boost. It’s easy to start but seriously competitive, and the leaderboard always tempts you to climb one place higher.
