I love Yahtzee, so I will play with friends; however, I thought I would play the Cheshire Cat challenge. Like other challenges, their opponent always gets a Yahtzee. The Cheshire Cat got 3 in one game, and I started getting only two matching dice towards the end, and they would not be the ones I needed. At the end, all I needed was 3s, and for my last three turns, I got 1 three. I can only therefore conclude that the program is written to cheat for their side so you will pay to play again. The only time I have paid to play was for a game I enjoyed and mastered all the levels. I paid for the next set of levels.
