Thirteen rounds. Each turn you roll five dice up to three times — tap a die to hold it between rolls — then score the dice in one empty box.
Upper section: Ones to Sixes count only that number. Score 63 or more up there and you get a 35-point bonus.
Lower section: Three and Four of a kind score the total of all dice. Full house 25, small straight (four in a row) 30, large straight (five in a row) 40, Yahtzee (five alike) 50, Chance is the total of the dice.
A second Yahtzee scores a 100-point bonus if your Yahtzee box holds 50, and acts as a joker: it must go in the matching upper box if that is open, otherwise in any lower box at full value.
Every box must be filled — sometimes with a zero. Highest total after thirteen rounds wins. Solo games keep your best score.
Undo takes back your last box choice (never a roll). Games save automatically — leave and pick up later.
Keyboard: Tab to the dice, Roll button or a dashed box, Enter or Space to press it.
