Hashi — Puzzle Fern

Hashi is a bridge-building logic puzzle. Join visible islands horizontally or vertically with one or two bridges. Every island must have exactly its printed total, bridges cannot cross or pass through another island, and the finished network must connect all islands. This independent implementation includes 12 original 7×7 and 9×9 layouts, each checked for one solution. Choose a layout, tap two islands or drag between them, undo a move, reset the board, and check your work. Progress is saved separately for each puzzle in the same browser. It is a finite collection, with no daily schedule or calibrated difficulty labels. Play free without an account. The HTML5 build includes the full puzzle set and runs locally from its uploaded files. Portal saves are separate from puzzlefern.com and other hosts. Optional footer links lead to the original Hashi page and the wider Puzzle Fern collection. The portal shell differs from the website and does not include its Focus-mode button. The screenshots show actual browser gameplay on the original site. Developed with AI assistance. There is no live AI, analytics, ads or remote game-data service in the uploaded build. The code, puzzle layouts and vector art were created for Puzzle Fern. No third-party game package or puzzle catalogue is included. 收起
