Game control method, game control device, and recording medium

A server comprising a processor, the processor configured to:

• provide a game, in which two or more users composing a group cooperate, implemented by a native application installed into a communication terminal,
• in the game, the processor is further configured to:
• receive, from a first user, a first instruction to create a group;
• create the group in response to the first instruction;
• receive, from a second user, a second instruction for the second user to join to the group;
• make, in response to the second instructions, the second user to belong to the group;
• conduct a main cycle;
• and
• conduct a sub cycle;
• wherein
• in the main cycle, the processor is configured to:
• display a deck creation screen;
• create, in response to a user operation to the deck creation screen, a deck including a plurality of card characters, wherein a plurality of parameters are set on each of the card characters, the plurality of parameters including a first parameter indicative of a hit point, a second parameter indicative of an attack power, and a third parameter indicative of speed;
• conduct a card battle based on the plurality of parameters set on each of the plurality of card characters included in the deck;
• and
• increase, by elevating a first card character among the plurality of card characters by consuming at least one card character identical to the first card character, at least one of the plurality of parameters set on the first card character;
• and
• in the sub cycle, the processor is configured to:
• make an event to occur;
• provide at least two component items;
• provide, when users belonging to the group have all the component items necessary to obtain a benefit, the benefit to the users belonging to the group;
• and
• finalize the event after a first term lapses from an occurrence of the event.

A non-transitory computer-readable storage medium having stored thereon computer-executable instructions, which, when executed by a processor of a server, cause the processor to provide a game, in which two or more users composing a group cooperate, implemented by a native application installed into a communication terminal,

• in the game, the processor is further configured to:
• receive, from a first user, a first instruction to create a group;
• create the group in response to the first instruction;
• receive, from a second user, a second instruction for the second user to join to the group;
• make, in response to the second instructions, the second user to belong to the group;
• conduct a main cycle;
• and
• conduct a sub cycle;
• wherein
• in the main cycle, the processor is configured to:
• display a deck creation screen;
• create, in response to a user operation to the deck creation screen, a deck including a plurality of card characters, wherein a plurality of parameters are set on each of the card characters, the plurality of parameters including a first parameter indicative of a hit point, a second parameter indicative of an attack power, and a third parameter indicative of speed;
• conduct a card battle based on the plurality of parameters set on each of the plurality of card characters included in the deck;
• and
• increase, by elevating a first card character among the plurality of card characters by consuming at least one card character identical to the first card character, at least one of the plurality of parameters set on the first card character;
• and
• in the sub cycle, the processor is configured to:

• provide at least two component items;
• provide, when users belonging to the group have all the component items necessary to obtain a benefit, the benefit to the users belonging to the group;
