Balls with numbers from 1 to 10 are placed in 8 rows by 4 columns on the field. The idea is to make the sum of balls values in some row equal to 21 (Black Jack). You may delete any ball - click on it. The whole balls column over this deleted ball falls down for one cell. This way you may change the balls sum in the row. Try to make 21, and the busty stripper will undress to the next level!
