Hi Roland,
For the Buchstabenplatten example in the instruction book, you say "Every plate must contain either two letters or two black cells."
But in the top-right corner of the 8x8 puzzle there are two plates, one with black+B, and one with black+C.
Is this an error, or an extra 'twist' to the puzzle?
