Rules & objective
Connect islands along their row or column to the nearest island in that direction. Bridges may not bend, run diagonally, skip an island or cross another bridge. A pair can carry one or two bridges. Each island number is the exact total of bridges touching it; double bridges count twice. All islands must form one connected network. Matching every number in separate groups is not a win. Choose an origin and a destination to preview, then choose one/two, erase, or mark no bridge and confirm. Erase clears a note too. A no-bridge note is optional and can be revised. These 90 original puzzles use 7×7, 9×9 and 11×11 grids, 30 of each with rotations/reflections; all have unique solutions verified from their public numbers. Hints infer one forced step from numbers, crossings, connectivity and current choices, without reading an answer key. A hint only previews and needs confirmation. Check reports constraint consistency, not guaranteed correctness of every unfinished choice. Undo/redo restore actual actions; Restart keeps this puzzle and New chooses another.
Controls
Play directly on the cards or board with mouse or touch. Coordinate selectors are optional keyboard aids.
Worked example
An island clue of three can be met by one double bridge and one single bridge. Bridges cannot cross, and the entire network must connect.
