Lanterns: Light Up Puzzle

Light every tile and bring a hidden world back to life.

Lanterns is Akari, also called Light Up: a puzzle of pure deduction. Place lanterns so every open tile glows. Numbered walls tell you how many lanterns must touch them. Light stops at walls, and no two lanterns may shine on each other.

Meet Pip, your lantern-moth companion, and explore over 10,000 puzzle rooms across 834 floors. Restore chapter landmarks as you progress, and take a break with Firefly Flight at chapter restorations.

Campaign puzzles have no countdown. Take your time, mark your plans, use free Undo, and follow Why explanations on the board. Your unfinished campaign puzzle stays ready when you return.

The Daily challenge brings one timed puzzle each local date: ninety seconds, one attempt, no hints or revives. Keep your daily streak going and look back on your results.

See a score out of 100 after each campaign win, celebrate your personal best, and choose lantern styles as you make the world brighter.

If you enjoy Nonogram, Picross, Sudoku, Hashi or Nurikabe, try a different kind of logic puzzle. Each board is generated and checked for a unique solution.

Lanterns is free to download, with optional in-app purchases. Campaign entry tickets recover over time. Between-level ads may appear after the introductory levels; a one-time purchase removes forced ads permanently. Rewarded videos remain optional. No sign-in is required to play.
