About this game
Bridges is a grid puzzle from Simon Tatham’s Portable Puzzle Collection, based on Hashiwokakero. Each island displays its required number of bridges. A bridge runs horizontally or vertically to the next island, never cuts across another bridge, and normally can be doubled. Every island has to be reachable from every other island.
Drag between two islands to draw a bridge. Repeat the drag to build a second one, then once more to remove the pair. Once the small grids feel familiar, the Type menu offers larger boards and harder deductions.
