A new game will be created with a code for you to send to the people you want to play with. Don't start the game until everyone has joined! The number of tiles each person gets depends on the number of players.
Once everyone has joined, click start!
Drag and drop your tiles to rearrange them.
To play, select the tile you want to play from your hand at the bottom of the screen, and then select the spot where you want to play that tile. Then click "Play"! (Don't worry about flipping your tile - the game will line them up for you.)
If you can't play, click the black tile on the right to draw one from the pot.
If you still can't play the new tile from the pot, click the train button to put your train up.
You can play on any train when the train is up. You can always play on the Mexican Train.
When someone plays a double, it must be "satisfied". You must play another tile with a matching number. If you cannot, you must put your train up and then the next player must satisfy the double. Normal play does not resume until the double is satisfied.
