I love Yahtzee, grew up playing it. But this app is horrible. It is very slow, lags horribly, and freezes... very often to the point you have to close and reopen the app. The worst part is, they know it. You'll get a message on the screen saying that they are experiencing delays, sorry for the inconvenience. Many of the different games in the app can only be played for free once in a certain time period. So in order to keep playing, you better be winning constantly or paying real money.
