Ideal 4-Way CountDown Game is a fun and educational game that will challenge your addition, subtraction, multiplication and division skills by simply using the numbers on the dice. The game starts by each player laying down all (10) of their wooden keys on the 4-Way CountDown unit. The first player rolls the dice in the center of the game board and the 2 numbers rolled must be converted into 1 number by using various methods explained on the instruction sheet. For example, if you roll a 3 and a 1, you could make it a 4 by adding, 2 by subtracting or 3 by multiplying or dividing. Flip up whichever number key is down. Be careful though, roll a double 6 and all of your keys go back down, or roll 11 and all of your opponent's keys go back down. The first player to flip up all 10 keys on his or her side of the playing board wins the game.
