Lighthouses: Logic Puzzle

About

Lighthouses is a calm logic puzzle. Every numbered lighthouse tells you how many ships it can see along its row and column. Find all the hidden ships by deduction alone. THE RULES • A lighthouse counts every ship in its row and column. It sees past other ships and lighthouses. • Every ship is seen by at least one lighthouse. • Ships never touch each other or a lighthouse, not even corner to corner. • Each puzzle has exactly one solution, so you never have to guess. DAILIES Five new puzzles every day, from a 6×6 Morning Mist to an 11×11 Midnight Watch, plus a Sunday Challenge each week. Keep your streak going, let a streak freeze save a missed day, and share your time with friends. VOYAGE 100 puzzles in five packs, from Calm Waters (5×5) to Stormy Seas (12×12). Each pack opens when you finish the one before it. HINTS THAT TEACH When you're stuck, a hint highlights the next cells you can work out and explains why in plain words. Check your grid at any time to see whether a mark is wrong. CAPTAIN'S LOG Follow your streak, best streak and perfect clears, and climb the ranks from Deckhand to Harbour Master. THE DETAILS • Hand-drawn art in a day and a night version. Pick one, or let it follow your system setting. • Undo and redo.
