Number Jumbler

Number Jumbler consists of seven dice in a plastic container called a jumbler.

From the box:
"Get the five colored cubes as close as possible to equaling the sum of the two black cubes. Mix the cubes by rolling NUMBER JUMBLER against the palm of your hand. Add the two black cubes to set your target number. Pick a time limit if you choose; use your watch as a timer. Using any mathematical functions you know (+, -, x, /, etc.) in any combination or order, try to come as close to the target number as possible. At the beginning of each round all players must agree on which math functions can be used. Extra points are given for equaling the target number. Use each colored cube only once."
