Enter the room code from your host.
Start a lobby and share the room code with players.
Either join or create a room to start playing. If the game has not started yet, you can collaborate on spaces to fill the board.
Once all of the spaces are filled (24 or more), the game can be started. Then player then inputs their name to get their board, which is randomized and unique to each them.
Save your url— that's how you'll join the game again later. Feel free to bookmark it, add it to your home screen, or whatever. You can also just remember the game code and the name you used to rejoin. Or use the recent games list to join a game you've played before.
The game is saved automatically, so you can come back to the same game later. Have fun!
