Unblock and arrange the falling stones in this novel and innovative game of logic. The beautiful hand-crafted puzzles will relax you mind. Slide the blocks in the correct order to fit them into the target area. But watch out: Once the stones have fallen down, they cannot be moved upwards again. Finding the solution — when the last stone snaps into place — is a deeply satisfying experience. The name “Kestli” (pronounced KEST-lee) means “small boxes” in some German dialects and also sounds similar to the name of this game’s inventor, Johannes Kestler. Features: • Puzzle packs with various sizes and difficulty levels • Daily puzzles for your daily extra dose of joy • No internet connection required (except for downloading new puzzles) • Hints available if you are really stuck
