Printable hashi
Hashi grids in PDF, from 7 × 7 to 11 × 11. Join the numbered islands with straight bridges, one or two between two islands, never crossing, until they form a single network; the number on each island says how many bridges reach it. One solution per grid, found by deduction; the solutions are at the end.
How it works
Pick the difficulty
Easy gives a 7 × 7 grid of about eight islands, medium a 9 × 9, hard an 11 × 11 with more than twenty islands and longer deductions.
Set up the booklet
Choose the number of grids, A4 or Letter paper, and whether solutions are added. Four grids fit on a page, with cells of at least 7 mm.
Print and play
Draw the bridges in pencil, with a ruler if you like. Start with the islands that have only one way out: a 4 in a corner, a 6 on an edge or an 8 in the middle get two bridges in every direction.
Printing tips
Choose “Actual size” or “100%” in the print dialog, not “Fit to page”, to keep islands big enough to read the number and draw the bridges between them. Black and white is enough: islands are black, the bridges on the solution pages are grey. Play in pencil so you can erase a bridge placed too fast. For a class or a club, print the solution pages on a separate sheet and keep it.
Frequently asked questions
What are the rules of hashi?
Every island carries a number, which is how many bridges are attached to it. Bridges are straight lines, horizontal or vertical, with at most two bridges between the same two islands. A bridge never crosses another bridge or an island, and all the islands must be linked into one group.
Does each grid have a single solution?
Yes. Every grid is checked before layout: exactly one solution exists, and it is found by deduction. No guessing needed.
Can I use them in class or in a club?
Yes, freely, including printing them in quantity. Only reselling the files is not allowed.
Are my settings saved?
On your device only, so you get the same difficulty next time. Nothing is sent to a server.
