Hashiwokakero — connect the islands, cross nothing
Updated Oct 31, 2026
Bridges, known in Japanese puzzle magazines as hashiwokakero and often shortened to hashi, gives you numbered islands and asks you to join them with horizontal and vertical bridges. Each island takes exactly as many bridge ends as its number, at most two bridges run between any pair, bridges never cross, and when you are done every island must be reachable from every other. That last rule, connectivity, is what separates it from ordinary counting puzzles and makes the endgame interesting. Sizes are 7×7, 9×9 and 11×11, each with a printable PDF and answer key.
