Sun Doku is based on the Japanese puzzle Sudoku which roughly translated means ‘single number’. It has been the most popular logic puzzle in Japan for 20 years. It requires no calculations or knowledge of maths – it works pure and simply on logic and elimination. Here you have 220 puzzles with three degrees of difficulty – Teaser, Toughie and Terminator. Infuriating and compulsive but great fun.
