Click the green flag to start the game. Click the red and green - and + buttons near the number of players to choose how many people will play. Click the yellow left and right buttons to choose the colors for each player. Once you've set the number of players and the players' colors, click the green Start button to start the game. While in the game, click the yellow Roll button to roll the dice. Then, click the dice that you want to keep and re-roll the rest. (A lock will appear below the selected dice.) You can also click the dice that you've kept to unselect them so that they can be rolled again. You can roll up to 3 times per round. That is, up to 2 re-rolls are allowed per round. After the third roll, you must select a category. To select a category, click an empty box on your scorecard. (A light red number will appear on it, indicating how many points that can be scored.) Then, click the green Confirm button to score that category. Once a category has been scored, it cannot be selected again for the rest of the game. The game ends after all players took 13 turns (one for each category on the scorecard). The player with the most points is the winner.
Even if you cannot score anything for the turn, you must still select one of the categories to score 0 on it. The categories and their scoring rules are as follows: Ones: Score all 1s. Twos: Score all 2s. Threes: Score all 3s. Fours: Score all 4s. Fives: Score all 5s. Sixes: Score all 6s. 3 of a kind: Score all dice if there are at least 3 of the same number. 4 of a kind: Score all dice if there are at least 4 of the same number. Full House: Score 25 if there are 3 of the same number with the remaining 2 of the same number. This means 5 of a kind can also count as a Full House. Small Straight: Score 30 if there are at least 4 numbers in sequence. Large Straight: Score 40 if there are 5 numbers in sequence. Yahtzee: Score 50 if there are 5 of the same number. Chance: Score all dice without any exceptions. If the sum of Ones through Sixes is at least 63, a bonus of 35 points will be added to your score. A Yahtzee bonus of 100 points will be added if you have 50 points in the Yahtzee box and get another Yahtzee on a later turn. If the Yahtzee box has 0 points, however, no Yahtzee bonuses are given to that player. The colors that can be selected are as follows: 1. White 2. Light Gray 3. Dark Gray 4. Black 5. Brown 6. Red 7. Orange 8. Yellow 9. Lime 10. Green 11. Cyan 12. Blue 13. Purple 14. Magenta 15. Rose 16. Pink The colors will cycle in the order above each time the yellow left and right buttons are clicked at the player selection screen. If at least two players choose the same color, the game will not start until all players in the game choose a different color.
