OBJECT OF THE GAME:
Be the first to call out "HIGH", "LOW", "HIGH/LOW", or "ZIPPY" after totaling the target number(s) shown on the green dice, with the numbers shown on the black dice using addition, subtraction, multiplication, and division.
There are three large green dice, two of which have the numbers 1,2,3,4,5,6 and one with the numbers 4,5,6,7,8,9. The die with the numbers 4-9 is used for the advanced game.
The six smaller black dice have the standard numbers 2-6, but the remaining side can be used either as a 1 or a 7, depending on the player's choice.
The 4-9 large die is set aside. All players play at the same time, taking turns as to who will be the 'roller'. The other eight dice (2 large and 6 small) are simultaneously rolled in full view of all the players, and must not be touched by ANY player.
The two Large Dice form a 2-digit number, which can either be high or low. For example, if the large dice show a 3 & 6, the low number would be 36 and the high number would be 63. Players study the dice and quickly call "HIGH", "LOW", "HIGH/LOW" or "ZIPPY" AFTER they have found a way of totaling either of the two numbers formed by the large green dcie with the small black ones using addition, subtration, multiplication and division.
The first person to call and get a correct result gets 1 chip, unless they call HIGH/LOW and show both answers - then they get 2 chips. You lose the same amount of chips if you are incorrect. If you call ZIPPY (which means no possible way to reach the target values) you get a chip from the bank unless someone challenges you. Then, whomever is correct pays the other.
The advanced version uses the 4-9 die in place of one of the other large dice for more challenging possible results.
UK players will see this as a dice driven version of the numbers quiz from the TV show Countdown.
