Hashi (Bridges)

About Hashi (Bridges)

Hashi, also called Bridges or Hashiwokakero, is the island-connecting logic puzzle, free to play in your browser. Each circle is an island with a number that says how many bridges must end there. Link the islands with straight horizontal or vertical bridges, using one or two between any pair, so that every island joins a single connected network. Bridges can't cross each other or pass over another island. Drag from one island toward its neighbour to build, drag again for a double bridge, and tap an island to lock it once it's done. Puzzles come in 7x7, 10x10 and 15x15 sizes with easy, medium and hard levels, so there's a quick warm-up or a long think whenever you want one. Your progress is saved automatically.

How to play

Drag from an island toward another to add a bridge; drag again for a double, once more to clear. Tap an island to mark it finished. No bridge mode (or long-press, then drag) marks islands that aren't connected. Mouse: left-drag builds, right-drag marks.
