LuXOR - A logic game

The Classic Light Puzzle

Free · In‑App Purchases

Every tap flips a light and its neighbors. Turn them all out in as few moves as you can. Freshly redesigned, with eight glowing themes and a new look on every screen. Turn out every light. LuXOR is a simple puzzle with a deep twist. Tap a light and it flips, along with its neighbors above, below, and to each side. Your goal is to switch the whole board dark. It sounds easy. Then the third tap undoes your first one, and you start to think. Every puzzle has a par. Solve it at par or better to earn all three stars, or come back later and chase a cleaner solution. There’s no timer and no rush. Just you, the board, and that satisfying moment when the last light goes out. HUNDREDS OF PUZZLES • 3800+ hand-picked puzzles across Easy, Medium, Hard, and Insane difficulty levels. • Boards from quick 5×5 grids up to 9x9 brain-benders • Browse every puzzle, and filter by unplayed or anything under three stars LEARN THE TRICK • A built-in Tips guide teaches “chasing the lights,” a method that solves any 5×5 board • Learn the patterns, the strategy, and a little of the math behind the game • Stuck? Tap Hint for a nudge in the right direction MAKE IT YOURS • Eight glowing themes, from classic white to deep red and indigo • A fresh design built for iPhone and iPad, in portrait and landscape WHY “LuXOR”? Lux is Latin for light. XOR is the logic behind every tap: press a light once and it flips, press it twice and it’s back where it started. Once you see it that way, the puzzles start to open up. LuXOR is free to play and supported by ads. Prefer it quiet? A one-time in-app purchase removes the ads for good. Made by one developer at BluMonkey Software, who still gets a kick out of the last light going dark.
