How it works
Create a game
Click the Create Game button. A unique game link is generated instantly.
Share the link
Copy the link and send it to your friend via text, Discord, WhatsApp, or email.
Play
When your friend opens the link, both browsers connect directly. The game begins.
How the connection works
This uses WebRTC - the same peer-to-peer technology used by video calls in your browser. Your moves go directly from your browser to your friend's browser, not through our servers. We use a public WebRTC signalling server (PeerJS) only to help the two browsers find each other - after that, all data is direct.
No game state is stored on our servers. If both browsers close, the game is gone. If you want to save a position, use the strategy guide's puzzle boards instead.
If the connection fails: School and work firewalls sometimes block WebRTC. Try using a mobile hotspot, or switch to Pass and Play mode if you are in the same room.
Playing on mobile
Both players can be on any device - desktop, laptop, phone, or tablet. The board adapts to screen size. Tap the column number at the top of each column to drop your piece. Works in portrait and landscape orientation.
Voice and video are not included - use Discord, Zoom, FaceTime, or a phone call alongside the game if you want to chat while playing.
