It’s a term to describe a fight between two players.
Rounds are the greater level of match. Each battle can have a fixed amount of rounds that the player can choose from a small list before searching for a game, and when a Player defeats all the Enemy’s Monsters, he wins a round. Who wins more rounds win the match. It is like a “best of three” system.
A turn happens when both players' Monsters have attacked at least once
An action is the moment where a Love Monster can act.
A round is the time frame when the Players fight against each other. All rounds have a lot of turns. A round ends when all Monsters on one side are down. A Player wins a match when they have 2/3 of the total rounds. For example, if a battle consists of 5 rounds, a player must win 3 out of 5.
