Guiding Light
Light the whole sea with lighthouses that never shine on each other. A new puzzle every day in Head Scratchers, one of DailyFlow's four puzzle worlds.
How to play
- Put lighthouses on the sea until every square of water is lit.
- A lighthouse lights its row and column until a wall stops it. Two lighthouses must never shine on each other.
- A number on a wall is exactly how many lighthouses touch it, side by side (not corners). Walls without a number can have any, or none.
- Tap water to put a lighthouse there, and tap it again to take it away.
Scoring
- Solving it within par (1:00) scores 100, then 80, 60, 40, 20, 10 for each 30 seconds over. The clock stops while the app is closed.
- Stuck? Hint points out a wrong piece, or shows the next step and why; tap it again and it's done for you, marked with a bulb so it stays put. Each hint adds 30 seconds.
- Show me the answer ends the game. Finishing always keeps your streak.
