13x13 Hashi Puzzles

The 13x13 hashi is the largest puzzle of the series: about forty islands over the whole page, and bridges that can join islands seven cells apart. Progress comes in waves, as each corner of the network settles and opens the next.

Three levels are offered, Easy, Medium and Hard, and each puzzle has one solution reached by reasoning. They are meant for solvers who already enjoy the 11x11 size and want a bigger network to build.

Working Region by Region

On a puzzle this size, solve one area at a time: finish the bridges of a corner, then follow the islands that link it to the rest. A completed region becomes a single block whose few exits are easy to read.

Hard Puzzles and Trial Bridges

At Hard, some decisions need a trial: imagine a bridge, draw its consequences lightly, and if an island ends up unable to reach its number, or a group gets closed off, erase and draw the other choice.

One Puzzle, One Page

One 13x13 puzzle fills the page, with islands large enough to read their numbers easily, whether you print a single sheet or the whole book.

Frequently Asked Questions

Can I print four 13x13 puzzles on one sheet?

No. Forty islands on a quarter of a page would leave too little room to draw bridges, so the largest sizes stay at one puzzle per page.

Does every hashi have only one solution?

Yes. The generator solves every puzzle with the reasoning of its level before keeping it, and it stays only when its bridges fit in exactly one way.
