This is extra-challenging, because the puzzle image isn't the same as the boxtop picture, and you have to decipher the clues on the in-box leaflet too. You can get extra clues by scanning the QR code - and if all else fails, use the final answer provided in the sealed envelope. Can you discover the 8 mysteries hidden within the puzzle and live to see another day? High quality 368 piece cardboard jigsaw puzzle. Suitable for ages 12 years and up. Made from strong premium grade cardboard, with linen finish print to minimise glare on puzzle image.
