The Krypt Silver Jigsaw Puzzle is designed for one thing only, and that is to be extremely difficult to solve. Normal jigsaw puzzles can be relatively relaxing or formulaic as solvers can use colors on the puzzle to get a sense of where pieces belong. This puzzle has no colors, and every piece is white, making it extremely difficult to make such inferences. Additionally, there is a huge variance in the shapes and sizes of the pieces, making it tough to sense any sort of pattern as well.
