What Is Squirm.io?
Squirm.io is a free online snake io game. You start as a tiny worm in a giant arena full of other players, eat food to grow, and try to become the biggest worm on the map without crashing. It runs right here in your browser on a computer, tablet or phone, and you can jump in as a guest with no account.
It’s a worm game with one simple rule: your head must not touch another worm’s body or the arena wall. Everything else is up to you. Play it safe and graze on food, or go hunting and cut other worms off so they burst into a feast you can eat.
How to Play Squirm.io
- Steer your worm with the mouse on a computer or with one thumb on a phone.
- Eat food to grow longer. The longer you get, the higher you climb on the leaderboard.
- Hold Boost to sprint. Boosting burns a little of your length, so use it when it counts.
- Cut off rivals. Slide across another worm’s path and it crashes into you, leaving its length behind as food.
- Stay off bodies and walls. Hit either one and your run is over. One tap and you’re straight back in.
Power-Ups
Power-ups appear around the arena and each one changes how you play for a short while.
| Power-up | What it does |
|---|---|
| Magnet | Pulls nearby food toward you |
| Feast | Makes the food you eat worth more |
| Telescope | Lets you see further across the arena |
| Nimble | Lets you turn tighter |
| Sprint | Makes you faster, and boosting costs no length while it lasts |
Skins, Characters and Events
As you play you collect gold Nuggets, the game’s own currency, and spend them on worm skins, painted characters, arena floors and food themes. Some worms can only be earned. Limited-time events bring their own arena and collectibles, and daily gifts, levels and achievements give you something to chase every time you come back.
Play With Friends
You can start a private arena, share its code, and play against people you know instead of strangers. The public arena has leaderboards for today, this week and all time.
Squirm.io Tips
- Eat first, fight later. A small worm loses nothing by being careful. Grow in a quiet corner before you go looking for trouble.
- Boost to cut, not to travel. Sprinting everywhere shrinks you. Save it for the moment you can get in front of someone.
- Circle smaller worms. Once your body closes the loop, they have nowhere to go.
- Watch the big worms crash. When a giant goes down, there is more food on the floor than anywhere else in the arena. Get there fast, and watch who else is coming.
- Size makes you a target. The longer you are, the more body there is to defend. Coil up when the arena gets crowded.
- Grab Telescope before a fight. Seeing further means seeing the worm that is about to cut you off.
Squirm.io on Phone and Tablet
The game is built for touch as well as a mouse. Steer with one thumb and hold the Boost button with the other. On a phone, tap Play and the game opens to fill the screen.

How do I get bigger faster in Squirm.io?
Eat steadily while you are small, pick up power-ups like Magnet and Feast, and head for the spot where a big worm has just crashed. Cutting off another worm is the fastest way to grow, and the riskiest.
Does boosting make you smaller?
Yes. Boosting burns a little of your length while you hold it, so short bursts are better than long ones. The Sprint power-up lets you boost for free while it lasts.
