This game is a "Mastermind" variation. The computer has selected 4 of the 7 objects on the right side (max.1 of each type). Your task is to find out these 4 objects in the right order. To select an object click on it by mouse or press one of the numbers from 1 to 7. You will get a whole circle for a correct object that is at the correct position and you'll get an empty circle for an correct object if the position isn't right. You can try only seven times (but this is sufficient).

In this picture the correct combination follows necessarily. There is no other combination that would fit to the first three evaluations. After you have pressed on the last missing object, the game is solved. Then the computer will tell you what he thinks about your choice.
