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.
