Candle Rook Lamps

Candle Rook Lamps is a quiet lantern-lighting puzzle drawn like a page from an old printer's manual: cream paper, ink-black walls and hard-edged amber beams. Every room is a grid of pale floor tiles and solid walls. Set a lamp on a floor tile and it lights its own square plus four straight beams, running up, down, left and right until a wall or the edge of the room stops the light dead. Your job is easy to state and delightfully stubborn to finish: light every single floor tile. Two rules keep you honest. No lamp may see another lamp, so if two lamps share a row or a column with nothing between them they are staring at each other and both flag red. And a wall showing a number must touch exactly that many lamps, counting only up, down, left and right, never diagonally. Blank walls ask nothing of you. WHAT IS INSIDE - Three room sizes: a 7x7 study, a 9x9 hall and an 11x11 great room - Endless rooms, drafted fresh every time you tap New - Every room is verified to have exactly one solution before you ever see it, so you never have to guess - Live illumination, with tiles washing warm the instant a beam reaches them - Pencil dots for marking the tiles you have ruled out - Unlimited undo, a clear button, and a hint that places one genuinely correct lamp - A clock on every room, with best times kept for each size - Twelve awards, from First Light to Rook Archivist - Stats that survive a restart: rooms finished, lamps set, hints taken and your longest hint-free streak - An illustrated rules tab with working diagrams of a blocked beam and of two lamps meeting BUILT TO BE QUIET This is a completely offline app. It never uses the internet. There is no account, no sign-up, no advertising, no analytics and no tracking of any kind. There is also no sound at all, not a click and not a chime. The only feedback beyond the artwork is a short optional haptic tick you can switch off. Play it on a plane, on a train, in a waiting room or in bed without disturbing anybody. Nothing is locked, nothing is timed against you and there is nothing to buy. Every room, every size and every award is available from the first launch. The board is drawn entirely from vector shapes, so it stays crisp on any screen, and the warm paper palette is kind to the eyes in a dim room. If you enjoy sudoku, nonograms or minesweeper, this is a different animal: pure deduction about light and sight lines, with no arithmetic and no luck involved. Pick a size. Set a lamp. Light every corner.
