Bulls and Cows

In this implementation version of the game, you play without an opponent and guess the number of the target program. Moreover, unlike the classical version of the unknown number may be 3-and 4-and 5-digit (depends on the settings you choose). Also, if you play a "Tasks", depending on the complexity of the game you will limit the number of attempts, at the same time, the numbers of which is the unknown number will not necessarily be from 0 to 9.
