Controls
Boosting makes you faster but costs length, and you leave a trail of pellets behind you. A brand-new snake is too short to boost.

- Steer: touch the right half of the screen and drag the way you want to go.
- Boost: hold to speed up.
- Item: shows up when you hold one.
- Look around: hold and drag.
- Game options: Face up, steering, Appearance and Return to lobby.
- Minimap of the whole planet.
Prefer a joystick? Open Settings, then Controls, and set Mobile steering to Joystick. The joystick appears where you touch the lower right of the screen.
Stay alive
Only your head is vulnerable.
Your head hits a body: you're out.
A head hits your body: they're out.
- Other snakes: if your head touches another snake, you're out. If another snake's head touches your body, they're out. You can't run into yourself.
- Head-on: whoever hits first is out. If you hit at the same moment, you're both out.
- Teammates: in Trios, touching a teammate is just as dangerous.
- Cacti eliminate you. Trees, rocks and mountains are solid, and your head slides along them.
- Water: your head can stay under for about 10 seconds. You're out when the oxygen bar runs out.
- Magma eliminates you almost at once.
- The storm (Battle Royale) eliminates you after about 7 seconds outside the safe area.
After you're out
Battle Royale: choose Play again to find another match in the same mode (your party stays together), Spectate to watch the rest of the match, or Return to lobby. In Trios you can watch only your living teammates.
Infinite: the game goes back to the menu. Press Play to start again with a new snake.
Connection trouble
On a phone, keep the game open while you play. Switching to another app disconnects you.
If your connection drops in Battle Royale, come back within about 15 seconds to keep playing. After that your snake is eliminated, but you can still see your result. In Infinite, disconnecting ends your snake.
If the game says Update required, update the app or reload the page before playing again.
