Rematch

Dasher makes it easy to ask your last opponent for another game. After your game is over, click the icon from the toolbar above the game board:

You can also use the Main console and type the server command: rematch

If you just completed a Pure-play game, the post-game toolbar will allow you to play again in the same pool instead of rematching the opponent you just played in that pool.
