BMS is played in rounds, by players or group of players competing with each other.
In the game, there are two categories of objects:
Each digital object can "connect" with some of the artifacts found in the museum's halls. Therefore relationships are created between digital and physical objects, which have as a result potential "background" stories to emerge.
The aim of the players is to identify one of the artifacts, which can be connected to the digital object that they have been given at each round, and then to make the connection between those two and gain points.
The winner is the player who, at the end of the game, has managed to gain the most points.
