This is a spin on the classic Jenga game. Each tile has a pair of 8mm x 8mm cylinders (one on each end) where you can drop in a 5mm-6mm sphere magnet to add a devious twist to the game. I recommend adding the magnet about 80% of the way through the print and to not add them in tiles right beside each other on the bed. For a full "regulation" set, print 54 tiles. For the full effect, don't add magnets to every tile and don't add magnets on both ends.
