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 fade and get a second ring.
Keyboard: arrows move between islands. shift + arrow adds a bridge that way, alt + arrow takes one away. space selects an island, then pick a neighbor. ctrl + z undoes, ctrl + shift + z redoes (cmd on a Mac).

Hard puzzle of the weekAbout unlimited Bridges
Easy maps solve by counting alone. Medium adds the rule that no group of islands may be cut off, and Hard needs short chains of “if this bridge were single”. Your progress on the current puzzle is saved on this device.
