A player chooses how many "small" and "large" numbers they would like to make up six randomly chosen numbers
Small numbers are between 1 and 10 inclusive, and large numbers are 25, 50, 75, or 100
All large numbers will be different, so at most four large numbers may be chosen.
The players have to use arithmetic on some or all of those numbers to get as close as possible to a randomly generated three-digit target number (ranging from 101 to 999, inclusively), within the 30-second time limit
Fractions are not allowed—only integers may be used at any stage of the calculation, (e.g multiplication, addition, subtraction, division)
Points are awarded for the closest solution, and again both players score if the solutions are equally close
10 points are given for an exact answer, 7 points for a non-exact solution up to 5 from the target, and 5 points for a solution between 6 and 10 from the target
