Celebrating its third year the global celebration is designed to bring all manner of brain-manglers together from Jigsaws to word games, number solving Soduku style stuff to board games, pretty much anything that is puzzling (does not include this years self-assessment). So, get in on the action and head over HERE for some free puzzle downloads or get social with puzzlers across the planet with #NationalPuzzleDay. The folks at Spinmaster have just told us about their retro jigsaw range, we think the Blockbuster VHS box will be the key in getting folk to the buy button, retro-tastic are they not? Anyways, for other puzzlement playthings we recommend a trip to Whirligig Toys, an eclectic collection of grey mater breakers to be found right HERE.
