Puzzles are reportedly selling better across the world than they do at Christmas time.
They are made by pasting images onto cardboard (images that evoke a sense of ‘coziness’ are always popular).
An elaborate cookie-cutter machine then applies 1,000 metric tonnes of pressure to cut the pieces.
The cutting tool for a 1,000-piece puzzle uses up to 230 feet of steel.
The edges of the tool dull eventually, and can be sharpened once before it has to be discarded.

Check out the amazing one-color puzzle below, though – from Japan.
The Japanese name for it translates to Pure White Hell Daio.
