In 2005, designer Kai Haferkamp released **Das Kleine Gespenst** (The Little Ghost), a memory game that transports children straight into the heart of Castle Eulenstein. The storyline follows a tiny ghost’s midnight quest to uncover hidden items in mysterious rooms. Each hour, the castle’s great tower displays an image on a window, indicating what players must find behind closed doors. To open each door, players use a set of magnetic keys that glide and unlock spaces as if guided by a ghost. Successfully opening a door earns the player a shiny cannonball, which will be used later in the final dexterity challenge. The ultimate goal is to accumulate the right number of cannonballs to win, and this number is determined in the dexterity game that takes place in the knight’s hall. The game is quick and fun, with 15‑minute rounds suitable for kids aged five and up. Components are simple and of good quality: illustrated cards, magnetic keys, and a castle board. While the theme is charming and the memory mechanic accessible, the game can feel repetitive after a few rounds, and the short playtime may not satisfy those looking for a deeper experience. Overall, **Das Kleine Gespenst** is a solid pick for anyone seeking a light, family-friendly game based on a classic children’s book that stimulates memory and attention in a spooky adventure setting.
