Bridges

Find a way to come together.

Match each island’s number with bridges, then bring every island into one connected network. No crossing allowed.

Easy, Medium and Hard are the original generator settings, not human-calibrated difficulty ratings.

A bridge between neighbours

1. Tap an island to select it, then the nearest island in the same row or column. Repeat that pair to cycle through one bridge, two bridges, then none.
2. Each number is the exact total of bridges touching that island. Two parallel lines count as two bridges. The small number below a clue shows your current total.
3. Bridges must be horizontal or vertical. They cannot cross another bridge, pass through an island, or connect diagonally.
4. All islands must form one connected network. Matching every number is not enough if there are separate groups. Loops are allowed.

Tap the selected island again, use Cancel selection, or press Escape to cancel. Green ✓ means that island’s number matches, not that the whole puzzle is solved. A red ! means too many bridges. A move without a warning is not guaranteed correct.

On small screens, scroll inside the board for 44 px tap targets. Whole-board view is a read-only overview. Keyboard: Tab to an island, Enter or Space to select it, arrow keys to focus its nearest neighbour, then Enter or Space to build. Focus remains on that island after the move.

Undo reverses a move. Restart asks first and clears this attempt, but keeps its completed mark and best result. Your last 200 moves can be undone, including after reload. Progress stays in this browser when storage is available.
