Consider the 7 magical squares in the diagram below.
Suppose person A is thinking of a number between 0 and 26.
She tells person B the colours of the magical squares that it is contained in.
Can person B figure out exactly which number person A is thinking of?
- This problem is inspired be a cute puzzle found in a Christmas Cracker :)
