Ive owned a number of different Yahtzee type games on a number of different systems from a TI-99/4 to todays PC. Yahtzee has always been that involving luck and strategy game that you can play solo or with a group. For my iPhone, I first bought Motion X Poker. Great game. Great graphics. But, its not Yahtzee and I didnt want to use pencil and paper. To play Yahtzee on my iPhone, I took the no frills route and bought iDice for 99 cents. With the latest update adding high scores, I have no complaints.
