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.
