Lighthouses & Boats (Tents)
Every lighthouse on the map needs a boat anchored beside it.
Rules
- Every lighthouse needs exactly one boat in a cell directly next to it (up, down, left, or right).
- No two boats may touch, not even diagonally.
- The row and column clues show how many boats sit in that row or column.
Controls
- Click an empty cell to place a boat. Click it again to remove the boat.
- Right-click a cell to mark it as water (and right-click again to clear the mark).
- Click and drag to paint several cells at once with whichever action you started.
- On mobile, tap a cell to cycle through empty, boat, and water.
Tips & Tricks
- A row or column clue of 0 means every cell in that row or column is water.
- If a lighthouse has only one neighbour that could hold a boat, the boat goes there.
- Once you place a boat, mark all eight of its surrounding cells as water.
- When a row clue equals the number of unknown cells left in that row, every one of them is a boat.
