Who doesn’t love a good puzzle? Well, possibly anyone who tries this one, branded the ‘world’s most amazingly difficult’ maze by the scientists behind it.
The maze, a mesmerising pattern of curves and spikes, was inspired by a knight moving around a chess board – and a meteorite.
Knights, which move in an L shape, can visit every square on the chess board only once and return to their starting point in a pattern known as a Hamiltonian cycle.
