“Widely regarded as the world’s most prolific wellspring of logic games and brainteasers ... if anyone comes up with the next craze, it will be Nikoli”—The New York Times


Heyawake is a popular logic puzzle from Japan that’s new to these shores, and will  delight sudoku fans. Here’s how heyawake works: Dark lines divide the grid into many different “rooms.” Some rooms contain a number, which indicates the number of black cells inside that room. Black squares may not lie horizontally or vertically adjacent to another black square. The white squares must all remain connected to each other, and no unbroken line of white cells may extend into more than two rooms. Fans of sudoku and other puzzles will discover many exciting strategies that make solving heyawake a uniquely satisfying experience.
