Islands Hashi

New: Hashi Complete — one purchase clears every ad and opens all 34 archipelagos and 15 Shapes collections. Plus a Daily reminder at your hour.

Hashi is the bridge-building logic puzzle also known as Hashiwokakero — pure deduction, no luck, no clutter. Draw bridges between numbered islands until the whole map connects into one network. Simple to learn, deeply satisfying to master.

A grid of numbered islands floats on a quiet sea. The number on each island tells you exactly how many bridges must touch it. Connect them all so that every island is linked into a single network — with no crossing bridges and no diagonals. Every puzzle has one logical solution, and you can always reason your way to it.

HOW TO PLAY • Drag from an island to build a bridge; drag again for a double. • Tap a bridge to remove it. • Each island's number = the bridges touching it. • Bridges run straight, never cross, never go diagonal. • Win when every island connects into one group.

A WORLD OF ISLANDS Sail through 34 real-world archipelagos — the Florida Keys, the Hawaiian Islands, the Aegean, the Galápagos, the Faroes, the Whitsundays, Raja Ampat, Svalbard and more — each with its own handcrafted puzzles and a few words about the place.

PUZZLES WITH A SHAPE Fifteen Shapes collections cut the board into a silhouette — a heart, a star, an anchor, a boat, a key, a crescent, a wave. The same rules, with a picture waiting at the end.
