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 DeKoninck.
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. Happy Puzzling!
