Love Yahtzee and was excited to download this app. However, it has many issues. For some strange reason it always crashes during the,"Fun Fair" reward system and tournaments. The ads are crazy ridiculous with their frequency. I would love to be a paying customer, but my principal's will just not allow me to spend money on this app. This game is all about the dice. With that being said, you will either grind your way to play or pay to play. Hopefully they will fix the glitches to make this 5stars
