Is there an optimum strategy to Yahtzee?

work hard on the upper section. Four 5’s or 6’s go in the upper section.

full house seems easy to get, so I usually take the 3 of a kind in the upper section

leave the ones and twos for complete misses later on. For example, if you get a first roll has two one’s and nothing else - reroll all five dice, don’t use up the 1’s.
