My Secret Number II

Using logic and careful reasoning will help you guess the computer's random number. This game can be a little more challenging than My Secret Number, although the difficulty level varies from puzzle to puzzle.

Object of the Game

To guess the positive three-digit integer the computer has randomly chosen.

Game Instructions

In this game, the computer gives you a series of statements about the secret number. You must use these statements to determine what the computer's number is.

Once you know what the secret number is, enter it in the textbox, and click 'Guess!'.

Game Hints:

Not every statement will be useful to you. For example, one statement might be 'The product of the first two digits is less than 10.' Another might be 'The sum of the first two digits is less than 17.' Clearly the second statement does not 'narrow down' the choices at all.

You may want to have a sheet of paper handy to help you eliminate choices!
