I made Hashi as part of Puzzle Fern. Connect numbered islands using one or two bridges, without crossings, to form one connected network. Play 12 original 7×7 and 9×9 layouts checked for one solution, with Undo, Check and local saves. Free, no account, download, ads or timer. About 30% of the code was AI-generated; no runtime AI or daily mode. Desktop Chrome play was checked in the official itch embed. SlowDen-host compatibility and physical-phone testing are not verified. Original game: https://puzzlefern.com/hashi/
