This is REALLY cool! If you love puzzles (and money) then you are going to love this. It comes from MSCHF, the makers of the One Million Dollar Puzzle, and it guarantees that everyone takes home between $1 and $2,000,000 once you have finished your puzzle. All you do is buy the puzzle (it's 500 pieces) and finish it. Once you do, you scan the QR code and are entered for the prizes. I'm not sure about you but it DEFINITELY gives me more incentive to finish this sometimes frustratingly difficult task. lol! You can even buy more than one!
