Rules
Find the right color code! In each row a black key peg marks a color peg which is correct in both color and position. A white peg indicates the existence of a correct color peg placed in the wrong position. The same colors may occur more than once in a color code. (Each color is marked with a unique number which allows the filling with a single pen.)
