Game management device, game management method, and program

A game management method comprising:

• storing, by a computer, a list of a plurality of groups constituted of one or more members;
• searching, by the computer, for two or more groups of the plurality of groups that satisfy a merging condition and that can be mutually merged from among the plurality of groups with which a number of members have not reached an upper limit set in advance in a game and that are in a state in which it is possible to add a member;
• presenting, by the computer, a proposal for merging to the two or more groups that can be mutually merged, and accepts replies to the proposal;
• merging, by the computer, the two or more groups that can be mutually merged to generate a single group in response to receiving replies to an effect of accepting the proposal from the two or more groups that can be mutually merged;
• storing, by the computer, the list in association with group attribute information with each group of the plurality of groups;
• registering, by the computer and in response to two or more of the groups being merged, the single group in the list while deleting the two or more groups from the list;
• and
• registering, by the computer and in the list, the group attribute information of each of the two or more groups in association with the single group after merging.

A nontransitory computer readable medium comprising a program that, when executed by a computer, is configured to perform a method comprising:

• storing a list of a plurality of groups constituted of one or more members;
• searching for two or more groups of the plurality of groups that satisfy a merging condition and that can be mutually merged from among the plurality of groups with which a number of members have not reached an upper limit set in advance in a game and that are in a state in which it is possible to add a member;
• presenting a proposal for merging to the two or more groups that can be mutually merged and for accepting replies to the proposal;
• merging the two or more groups that can be mutually merged to generate a single group in response to receiving replies to an effect of accepting the proposal from the two or more groups that can be mutually merged;
• storing the list in association with group attribute information with each group of the plurality of groups;
• registering, in response to two or more of the groups being merged, the single group in the list while deleting the two or more groups from the list;
