To see your Games in Progress, select the icon in the lower left part of the main screen. There you can also see the status of the games you've won and lost, and the ones that are waiting for your opponents' turn. If you have more than one game in any of these categories, a drop-down menu will appear in the upper right corner of each box. In the 'Finished Games' section, you'll have the option to play again with the same opponent. To do this, select 'Play Again'.
