Puzzles, brain teasers, multi-player board games and about three dozen different version of Rubik's famed cube are only some of the products available at this tiny shop hidden beneath Slovenska Cesta in the passageway connecting Zvezda Park and Plečnikov Trg. Skills levels range from beginners and children up to the those that are virtually impossible to solve, so you shouldn't have any problems finding something appropriate. The shop assistant will also be glad to demonstrate everything - after of course allowing for enough time for customers to become frustrated with their own failed efforts.
