Daily Lumen: Light Up

Some days you just want one good puzzle. A quiet room, a few lamps, and the moment it all lights up. Daily Lumen is a Light Up logic puzzle (also called Akari). Every day you get one fresh grid, and it's the same grid for everyone in the world, seeded by the date. Tap an empty square to set down a lamp. Its light runs all the way down the row and column until a wall stops it. Keep placing lamps until no dark square is left, and never let two lamps shine into each other. A number on a wall tells you exactly how many lamps belong in the squares touching it, no more and no fewer. Light up every square and the room glows. That's the day done. There are no wrong moves and no clock pressure. Take your time and tap until it all lights up. THE DAILY RITUAL A new room each day, and the week eases up and then leans in: Monday: Gentle Tuesday: Easy Wednesday: Breezy Thursday: Medium Friday: Tricky Saturday: Knotty Sunday: Fiendish HOW YOU SCORE Each grid has a par time, the calm benchmark for an unhurried solve. Land on par for a solid three stars, and beat it for up to five. Your tier carries a name: Steady, then Sharp, then Swift, and Flawless for a truly fast, clean light-up. When you finish, you get a tidy result card to share that shows your stars, time, and streak but reveals none of the solution, so nobody's day is spoiled. KEEP YOUR STREAK Solve the daily grid each day to grow your streak. Miss a day and a banked freeze token quietly bridges the gap so your run survives. You start with one freeze, earn more at streak milestones, and can bank up to three at once. Turn on one gentle daily reminder if you'd like a nudge when today's puzzle is ready. All your stats, history, and calendar live on your device. PLAY WITH THE WORLD Two optional leaderboards through Game Center: today's fastest solves, and the longest streaks of all time.
