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.
