sudokucup.com

Hi all,
my question is related to sudokuro. I downloaded the booklet trying to solve the examples. In the sudokuro instructions, I read "the digits can be repeated in .. .. or 11 MARKED SHAPES". Now, opening the pdf using Adobe Reader on Windows, I'm not able to visualize these 11 different shapes... could you please do something to highlight them in a different way or explain better how I should distinguish them?

Thanks a lot!
