Hi Non-Twisty Puzzles fans, Triquadsplosion is a dexterous assembly puzzle. The object is to bring assemble the squares and triangles into a "Christmas coaster". It is rather boring puzzle, that I just needed to get out of my system. Watch the YouTube video. Buy the puzzle at my Shapeways Shop. Read more at the Non-Twisty Puzzles Forum. Check out the photos below. Enjoy! Oskar
