Abstract: A management terminal receives input of a game machine ID for identifying an object acquisition game machine and a prize ID for identifying a prize to be stored in an object acquisition game machine. A server associates the prize ID with the game machine ID to update object location information indicating the location of the prize. The object acquisition game machine is a game machine with which a player attempts to acquire a prize placed in a first region by moving the prize to a second region by manipulating a crane. The management terminal receives a prize ID from a code attached to a prize by reading the code with a predetermined reader.
