Good old Yahtzee! The game of luck and skill, knowing what to keep and what to roll, knowing where to hit first- using probability as if it were a skill to fill in more challenging slots before the easier ones to fill. Sometimes- it's worthwhile to use your three of a kind- on a number slot, if you're lacking especially in the number categories for the bonus. That being said, like most dice games, and Yahtzee is no exception, the reason probability is a skill here is because the game itself is a great deal of luck involved, and working around what you're given to win. All in all, Yahtzee was one of my personal favorites as a child- the one luck game I could sometimes win with!
