This game progress assistance system provides assistance in a game that progresses using game items placed in a field, and includes: a camera configured to capture an image of the field; a projector configured to project a projection image on the field; and an information processing apparatus. The information processing apparatus acquires object information including positions and kinds of objects corresponding to the game items, based on a captured image captured by the camera. On the basis of the object information, the information processing apparatus determines a combination that satisfies a predetermined first combination condition among combinations of any of first objects located in a first area in the captured image and any of second objects located in a second area in the captured image, and generates the projection image including a first combination indication indicating the combination.

An amusement game device is provided. The amusement game device includes a projectile launcher configured to launch a projectile, and a light-emitting device associated with the projectile launcher. The light-emitting device is configured to emit light for a first period of time towards the projectile at a time after the projectile has been launched by the projectile launcher. The amusement game may also include one or more projectors, such as for causing different target information to be displayed.
