Instructions for play:

Choose a divisor and the computer will give you some information about the number.

The fewer divisions you require, the more points you get:

If you guess correctly after

2 divisions - you gain 10 points

3 divisions - you gain 9 points

4 divisions - you gain 8 points

5 divisions - you gain 7 points

6 divisions - you gain 6 points

7 divisions - you gain 5 points

8 divisions - you gain 4 points

9 divisions - you gain 3 points

If you guess wrong you lose 5 points, even if your guess satisfies the criteria, so don't guess until you are certain that there is only one possible answer.

Each division you carry out must provide new information - it must rule out some numbers. If you carry out unnecessary divisions you gain 0 points, even if your eventual guess is correct.
