  • Patent number: 10974143
    Abstract: A terminal device includes a memory that stores, characters in a game, a plurality of slots into which action reservations for the characters are to be registered, an action sequence for each of the slots, and effects, a display, a receiver that receives a request of an action reservation for a first character, and a processor that outputs, to the memory, the request when the processor determines the first character is in an active state in which the character is allowed to register the action reservation. The memory registers the first character in an earliest slot in the action sequence among the slots in which no other characters have been registered. The processor causes the first character to execute an action associated with the slot according to the action sequence. The effect associated with the first character is applied to the executed action.
