Bridges

How to play

Connect every island with bridges. The number on an island is how many bridges touch it. Bridges run straight across or up and down, never diagonally, never cross each other, and there can be one or two between any pair of islands. When you're done, every island must be reachable from every other. The puzzle is also known as Hashi or Hashiwokakero.

Drag from an island towards a neighbour, or tap one island and then the other — each repeat adds a bridge, and a third tap removes them. An island turns solid when it has exactly the bridges it needs.

Shortcuts

• Arrow keys move, Shift + arrow builds a bridge from the island you're on.
• Z undoes, Y redoes, H asks for a hint.
