Boomerang Puzzle lets the computer guess a number the player is thinking of. The player will need to answer some questions, namely what the remainder is when dividing the number by 3, 5 and 7. The computer will always guess right and it's up to the player to figure out how the computer does it.

The puzzle first appeared in A.D. 90 in Arithmetica by Nicomachus.
