How to play
- Join the islands with bridges that run straight across or straight down.
- Each number says how many bridges touch that island. Two islands can share one or two bridges.
- Bridges can’t cross each other or pass over an island.
- Every island must end up in one connected network.
- Drag from an island toward a neighbor, or tap an island and then a neighbor. Each go adds a bridge, and a third clears them. Full islands turn grey.
Keyboard: arrows to move between islands, shift + arrow to add a bridge that way.
