Your objective is to select numbers from the grid and select operators to produce a required Answer (the number shown in the big black box at the top right corner) before the count down clock reaches zero. The more steps you use in your calculation to reach the answer, the higher a score you will get. A round is completed when all the numbers in the grid are used.
