All ages. Any number of players. Six dice. Paper and pencil for scorekeeping.
Alternate turns. On your turn, roll all six dice at once, one roll.
Score your turn as follows:
Each possible sequence of dice has a different point value. If you can make more than one sequence (each die can be used only once, though), then you add up the point values for all sequences.
Any sequence of 2 or more dice counts, but only use each die one time.
Score by adding the value of the dice in the sequence PLUS the number of dice in the sequence.
For example, if you roll 1, 1, 2, 2, 3, 4 you can create sequences of 1-2 and 1-2-3-4.
The 1-2 sequence scores 1+2 which is 3 PLUS 2 (because it is a 2-dice sequence) for a total of 5.
The 1-2-3-4 sequence scores 1+2+3+4 which is 10 PLUS 4 (because it is a 4-dice sequence) for a total of 14.
Together, the two sequences add up to 5 + 14 = 19 points for that turn.
Another example is:
You roll 2, 3, 3, 5, 5, 6. In this case you can make just two sequences a 2-3 and a 5-6. The 2-3 scores 2+3 which is 5, plus 2 for having 2 dice in the sequence, so the total for that sequence is 7. The 5-6 sequence scores 5+6 is 11, plus 2 for having two dice in the sequence, so that is 13. Total for the turn is 7 plus 13, for 20 points total.
You can make up rules to add a little more pizazz to this game. Maybe add a point for each even number rolled. Or add points for getting 2, 3, 4 5, or 6 of of a kind.
Play around with the rules and see if your changes make the game more fun. Let me know.
