This game uses a mathematical trick with the binary system.

You are presented with 6 pages, each seemingly showing random numbers. However, they are not random. If you look at the top left hand number, it is a power of 2: 2, 4, 8, etc. The numbers shown on each page are those that require this power of two when representing it in binary.

For example, 27 = 16 + 8 + 2 + 1, for this number you will have to press 'Yes' on the pages that have 16, 8, 2 and 1 in the top left corner and 'No' on the others.

You can print off the six pages and amaze your friends. Simply make a note to which pages they say Yes and keep a total of the top left hand numbers, remember to show the pages in a random order.
