Islands Hashi

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. A NEW PUZZLE EVERY DAY The Daily gives you one fresh challenge every day. Sign in to climb the daily, weekly and all-time leaderboards and see how you stack up against players worldwide. PLAY ALONGSIDE FRIENDS React to anyone's score with an emoji, follow the players you are chasing, and get a nudge when someone passes you. BUILT TO BE CALM • Smooth, forgiving drag controls with full undo, redo and reset. • Zoom and pan freely on larger boards. • Gentle coaching that explains why a move doesn't work — so you learn, not just lose. • Hints when you want one: each hint places one provably-correct bridge. • Light and dark themes, beautiful typography, no noise. RELAX AND THINK No timers forcing you, no penalties for experimenting. Whether you have two minutes or twenty, Hashi is a quiet place to think. Perfect for a coffee break, a commute, or winding down at night. Free to play. Optional in-app purchase for keys that unlock extra island groups and buy hints, and an optional account for cloud leaderboards. Build your bridges. Connect every island.
