All of your played rounds can be found by clicking Rounds button from the front page.
Scroll down or use search function to find your played rounds.
If you have rounds that you want to remove, click the trash icon from the top right corner and select the round you wish to remove. If you're the creator of the round you're removing, the app will ask you if you want to remove whole round or only from your account. Please do not remove whole round if other players have valid scores inserted.
