Quiet Lights

Quiet Lights is a calm logic puzzle. Light up every room. Place lamps on the grid and each one shines down its row and column until a wall blocks it. The board is solved when every white square is lit — with no lamp shining on another, and every numbered wall surrounded by exactly that many lamps. There is always one logical solution, and you never have to guess. Tap a square to place a lamp, tap again to mark a square you know stays dark, and follow the deductions until the whole grid glows. Four board sizes, from a compact 6×6 to a roomy 9×9. Four difficulty levels — Easy, Medium, Hard, and Expert — chosen independently of size, so you can take an easy 9×9 to unwind or a hard 6×6 to be tested. Play the Daily puzzle — one shared board each day, the same for everyone — or roll unlimited boards in Practice. Fifteen languages. Five themes — Light, Dark, Paper, Dusk, and a colour-blind-friendly Accessible palette with clear marks, so the grid stays readable for every kind of vision. Soft ambient music and gentle haptics, each with a one-tap mute right on the Home screen — no settings dive needed. An optional daily reminder nudges you back at the time you choose. No ads. No tracking. No accounts. Your progress and stats live on this device only.
