I created the Amazing Number game with 7 cards. These cards have starting numbers of 1, 2, 4, 8, 16, 32 and 64.
For any selected number, I find the combination of starting numbers that make up that number. For example, the number 13 is made from 1 + 4 + 8. So, I put the number 13 on these 3 cards.
If someone chooses 13 as the secret number, they will find it on the three cards starting with 1, 4, and 8. When they give the 3 cards to me, I add the starting numbers (1, 4 and 8) to get 13.
Easy, isn't it? This is the secret of "reverse engineering".
