Gulper.io is a free multiplayer snake game you can play in your browser right now, no download or account needed. It works on desktop, mobile, and Chromebook, so it runs unblocked at school or work wherever browser games are allowed. You control a glowing neon worm in a shared arena, eating orbs to grow longer while other real players try to do the same. Cut off a rival and watch them crash into your side. Everything they gathered becomes yours.

What is Gulper.io?

Gulper.io is an online .io game that crosses the classic Snake formula with Tron-style neon visuals and a live multiplayer arena. You and dozens of other players share one board filled with glowing food orbs. Eat to grow, grow to dominate, and outlast everyone else. The round never resets on its own. Your session ends only when you die, so survival time is the real score. The developer is tonsomar, and the game has been free to play since December 2018.

Controls and movement

All steering is done with the mouse. There are no keyboard movement keys. The table below covers every input in the game.

How the boost works in Gulper.io

Most snake and worm games shrink your body when you boost, trading length for speed. Gulper.io does not do that. You can hold the boost for as long as you like with no size penalty. That changes the tactics: speed is always available, which means the danger comes from steering, not from rationing a resource. Fast worms that cannot corner well die just as easily as slow ones.

Growing and eliminating rivals

The two core actions that shape every session are listed below.
