4 squares are placed on the screen. Each square has a table with (3x3) cells, numbered from 1 to 9. A ping-pong ball is moving inside each square. When the ball moves over some cell, its value is flashing. When you click on the square, the current flashing cell value becomes the value of the whole square. Try to make the Black Jack (21) on the sum of all 4 squares values. Click on squares to catch the ball on needed numbers. Sure, it helps to strip the busty girl on the city street!
