The Eternity puzzle is a geometrical jigsaw puzzle designed by British mathematician Alex Bellos and created by David J. Chalmers. Originally released in 1999, it consists of 209 irregularly shaped pieces that are meant to fit together to form a large, symmetrical shape, usually in the form of a 600-piece puzzle. The challenge is to assemble the pieces in such a way that they fit together perfectly without any gaps or overlaps.
