Rules

The objective is to find the colors of 4 hidden squares in as few tries
as possible.

Select a color by clicking on one of the balls on the extreme right. Place
any 4 colors of your choice on the middle 4 squares of the bottom row and
hit enter. You will get two numbers on the left. The number of black balls
indicates how many balls you've got in the correct position. The number of
white balls indicates how many balls you've got n the wrong position. Now
try again on the second row. Repeat until you get all four black balls.
