What is Hashiwokakero?

Hashiwokakero – Japanese for “build bridges!” – is a logic puzzle made popular by the Japanese puzzle publisher Nikoli. You may also know it as Hashi or simply Bridges. The board is a scattering of numbered islands, and the whole puzzle is deciding which of them to connect, and with how many bridges.

The rule

Four sentences, and that is the entire rulebook:

• Every island shows a number — exactly how many bridge-ends must touch it.
• Bridges run only horizontally or vertically, never diagonally.
• Two islands can be joined by at most two bridges — tap once for a single bridge, again for a double, a third time to remove it.
• Bridges can never cross, and every island must end up in one single connected network — no island left out, no separate group.

How to play here

Tap the water between two islands to build a bridge, tap again for a double bridge, and a third time to remove it. A mouse works the same way. Undo takes back your last move, and the hint button shows a next move you can prove.
