Play online with friends
Everyone plays on their own device, from anywhere, with their own controller. All it takes is a link: no sign-up, nothing to install, nothing to pay.
How to start
- 1Open the game and tap Play with friends.
- 2Send the link to whoever is playing.
- 3Everyone opens the same game on their own device, and the match begins.
How a match works
Each player runs the game on their own device from their own copy, and the site checks that all copies are identical before starting. The game file is never sent to anyone.
Only the buttons pressed travel between devices, frame by frame. That is why every screen shows the original picture, without the quality loss of video streaming.
On most consoles, each device predicts the other player’s input and corrects it instantly when wrong (rollback), so connection lag barely shows.
The room has text and voice chat, and the microphone starts off. In an open room, the host approves everyone who asks to join and can remove anyone.
Browsers connect directly to each other, so people in the same room can see each other’s IP address. Only play online with people you know. Learn more

No online play
These consoles work normally, but for one person only. On handhelds, linking two units is not emulated; on the Sega Saturn, the emulator cannot yet run a game exactly the same on two devices.
