If you think regular puzzles are too easy, this is a delightfully masochistic challenge. It is a 1000-piece puzzle that is entirely, blindingly white. Because the micro-sized pieces shrink the finished puzzle down to just 38 x 26 cm, you cannot rely on big shapes to guide you. It is purely about analyzing the tiny, subtle physical cuts of each blank piece. It is the ultimate test of patience for anyone who finds normal jigsaws a bit too predictable.
