A multiplayer Paper.io game you can play with friends

Butter.io is a free multiplayer territory game in the style of Paper.io. You steer a jelly cube around the map, draw a trail out of your land, and close the loop to claim everything inside it. Cross another player's trail to knock them out, and get home before anyone crosses yours. It runs in your browser on a computer or a phone, with no download and no account.

How to play

1. Pick a nickname and press Play. You join the next public match, which starts within 20 seconds.
2. Steer with your mouse. On a phone, touch anywhere and drag the joystick that comes up under your thumb.
3. Leave your land to draw a trail, then come back to claim all the ground the loop surrounds.
4. Run over another player's trail to knock them out. Your trail is just as open to them until you're back on your land.
5. A match lasts 3 minutes and you get one life. Whoever holds the most land at the end wins.

Play with friends

Press the friends button next to Play to open a private room. You get an invite link to send to your friends, and the match starts when you, the host, press Start. Matches have five players and bots fill any empty seats, so even two of you get a full game. When it ends, everyone stays in the same room for a rematch.
