Hashi
Build bridges between numbered islands. Bring them all into one connected world.
Tap two neighboring islands to add a bridge.
How to play Hashi
- Connect islands with horizontal or vertical bridges. A bridge cannot pass through another island.
- Each island’s number is the total number of bridges touching it. A pair of islands can have at most two bridges.
- Bridges cannot cross, and all islands must belong to a single connected network.
Make your move
Tap an island, then a visible neighbor to cycle the connection: no bridge, one bridge, two bridges. You can also tap the space between the islands.
