This game is kind of like Hangman, but with numbers. Guess the number in 8 tries or less, given the clues that you have. The game supports difficulty settings up to 16 digits long.
Some mathematical terms here may be a bit obscure. A glossary: Digital root - Add the digits of the number together, then do this recursively until there is only one digit left in the number. That number is the digital root. Evil numbers - Numbers whose binary representation contains an even number of 1s. Odious numbers - Numbers whose binary representation contains an odd number of 1s. Abundance - Take the factors of the number (excluding the number itself), add them up, and subtract the number from this total. Deficiency - Take the factors of the number (excluding the number itself), add them up, and subtract this total from the number. Perfect number - A number with no abundance and no deficiency, whose factors (excluding the number itself) are exactly equal to the number itself.
