This game works as follows: by some mathematical rule, I will assign 'odd' or 'even' to all elements of a set. Two elements combined in some way will give even if they are of the same type, and odd if they are not. The object is to guess the rule, by asking whether specific elements are odd or even.

The first set is the natural numbers (ie 1,2,3,4,5,6....)
