Bolleke - Puzzle Coaster
Last Saturday sitting in the pub and drinking a Bolleke (world famous in Antwerp - Belgium) I noticed a puzzle at the back of my beer coaster from brewery De Koninck. Object of the Bolleke-puzzle is to have the same number of open "bollekes" and solid "bollekes" for each row and column (Bolleke = circle). Nice puzzle but only before you start drinking "Bollekes". For people not familiar with Bollekes please have a look at the glasses they serve Bollekes in, from brewery De Konick.

Has anyone solved this?
Yes, they are quite fun and easy to solve once you get the hang of it (it helps to do them before any heavy drinking!).
You forgot to mention one rule though: in addition to having the same number of black and white circles in each row and column, you are only allowed to have two of the same color in a row or stacked on top of one another. Thus, if you have two white ones stacked on top of each other or next to each other, you know the ones on either side are going to be black.
Good luck!
