Based on the Countdown TV Game Show. The numbers round consists of a selection of 6 numbers with up to 4 BIG numbers and remaining SMALL numbers.
The BIG numbers 25,50,75 and 100 are selected randomly, with one of each allowed up to a maximum of 4. The SMALL numbers are random selected ranging from 1 to 9.
A random 3 digit TARGET between 100 and 999 is produced, with contestants having 30 seconds to use the numbers selected to get to within 10 of the target. The closest solution receives a point.
