We play two games of Yahtzee a week with my in-laws. My mother-in-law won the second game today, but I absolutely cleaned up in the first game. Four Yahtzees, including one on the first roll. Everyone was cursing me. It was unbelievable, definitely the highest score I've ever had.
My mother was disturbingly proficient at this game during her lifetime, to the point where I often suspected actual magic was involved.
