A very simple children's memory game with a haunted house theme. There are 21 pre-printed images on the board, showing seven different types of scary haunted house resident. 20 of these images are covered with randomly placed, face-down tiles.
On a turn, a player flips one tile and tries to match the tile revealed with the only image on the board not covered with a tile. If the tile matches, the player places it over the top of the pre-printed image, with the image side of the tile face up, thereby revealing a new pre-printed image to be matched where the tile was previously positioned.
Tiles that are revealed but don't match an image are also moved to a new spot to make it harder to match the token on future turns. Play continues until all tokens have been matched, and the winner is the player who matched the most images.

The old haunted castle is filled with lots of creepy characters, all trying to find their own shadow. A shadow is only visible when a window is open, but only one window is open at a time. Your job is to match up the shadow with the correct ghost. It takes a little bit of concentration, and a good memory is a big asset. But everyone starts with the same ghost of a chance to win.
