At the end of each game the app gives you the option of either quitting or playing another game. I completed 3 games after downloading the app and tapped the “Play Again” button every time. After the video ads were finished and it returned to the game, a roll had mysteriously disappeared. This happened all 3 times, so I’m confident that this was not an aberration. There are plenty of Yahtzee games out there, so this one is getting deleted immediately.
