About

Lightkeeper

Read full description

The lighthouse has gone dark, and the keeper has forgotten what it looked like. Every picture you solve is a memory it gets back. Lightkeeper is a nonogram — a picture cross puzzle, also called picross, hanjie or a Japanese crossword. The numbers along each row and column tell you how many squares to fill. Work out which ones, and a picture appears. NEVER GUESS All 500 puzzles are checked by a solver before they ship. Each has exactly one answer, and that answer can always be reached by logic alone. If you are stuck, there is something left to work out — not something left to gamble on. A TOWER THAT LIGHTS UP Puzzles are not a list. They are five floors of a lighthouse: the Lamp Room, the Keeper's Door, the Watch Room, the Winding Stair and the Lantern. Finish a floor and its windows come on for good. EVERY PICTURE IS KEPT Solved pictures go to the gallery, where you can look back at the whole collection. A PUZZLE EVERY DAY A new one each morning, the same for everyone, marked off on a calendar. MADE TO BE PLAYED ANYWHERE Plays fully offline. Portrait, one hand, on iPhone and iPad. Light and night themes. Drag to fill, pinch to zoom on the big grids, and cross out settled lines automatically if you want the help. FOR PLAYERS WHO LIKE Nonograms, picross, griddlers, hanjie, pic-a-pix, paint by numbers, logic puzzles, pixel art, and a quiet game to end the day with. Free to play. Optional hints and an ad-free purchase.
