Hard hashi is a puzzle of long-range consequences. On these boards a bridge drawn in one corner can block a route four islands away and decide the whole map, and the openings that carry you through an easy grid — the doubled 4s, the forced 1s — barely dent them. What works instead is patient elimination: proving a bridge impossible, marking it off, and letting the accumulated impossibilities force the remaining counts. Allow half an hour and expect to spend a good part of it not drawing anything.

Large hashi boards with high island density and plenty of long spans, one puzzle per page. The layout keeps island circles and clue numbers legible even where several bridges converge. Each puzzle is paired with an answer page showing the complete network with singles and doubles distinguished. Black and white on US Letter, one puzzle per sheet.

Frequently asked questions

How do I make progress when nothing is forced?
Work by contradiction on a single bridge. Assume a particular double bridge exists, follow the consequences for a few islands, and see whether it forces a count over its limit or isolates a group. If it does, that double is impossible — cross it off and re-scan. On hard boards this is the normal way forward, not a last resort.
Do hard hashi puzzles ever require guessing?
No. A well-formed hashi is fully determined by logic, with one valid network. If a puzzle seems to need a guess, there is usually an unmarked impossibility — a route already blocked by a bridge you drew earlier, or a pocket that would be cut off.
Why do bridges never cross?
It is a rule of the puzzle, and it is the main source of difficulty on a dense board. Once a long bridge is drawn, every crossing route is dead, which can cut a distant island's options in half. That is why experienced solvers hold back on long bridges until they are certain.
Are these harder than hard sudoku?
Different rather than strictly harder. Hard sudoku difficulty comes from chained candidate elimination in a fixed grid; hard hashi difficulty comes from spatial blocking and connectivity across a whole board. Some solvers find the spatial version far more intuitive, others much less.
