Did you know that you can talk with the friend you are playing against by using the game's Chat feature? Not only that, you can access it without leaving the board so you can continue playing. Here's how:
1. Tap the Chat icon at the upper right corner of the board.
2. Type your message then send.
On your tablet or phone, after you send your message, just simply tap on the board to close the Chat window and be back to the game!
On the Web version, and following the same steps showed above, the chat will show on the right side of the screen. Then, use you keyboard to chat with your friends!
