Welcome! This is a game of mastermind where the computer generates a serie of 4
random numbers ranging from 0 to 9. You have to guess what the serie is.

You will be asked to enter 4 numbers in a row, ranging from 0000 to 9999. After
you have entered you will see the following:
- first number: how many characters you have guessed correct, but not on the correct position
- second number: how many characters are both correct and on correct position
- the serie you entered

Enjoy!
