In Yahtzee, keep dice according to both the current hand and the open score categories. A high upper-section total may secure the bonus, while straights, full houses, and multiples have different probabilities and opportunity costs. Use remaining rolls to pursue a realistic category rather than switching goals after every die. Joker and bonus Yahtzee rules vary. For a scoring dispute, include rule set, roll sequence, kept dice, open scorecard, chosen category, and expected score.
