The rules of Kluster DUO are the same as those of Kluster: the magnetic stones are evenly distributed between the two players, who take turns placing a stone within the area defined by the string. The first player to place all their pieces wins. However, if the stones are targeted during a player's turn, they are knocked away.

During their turn, players can move the discs or make the discs jump by using the magnetic field of their own discs, or they can place them so close together that the slightest disturbance triggers a catastrophic chain reaction.

The magnets in the Kluster DUO game have a particularly original shape, making them more sensitive to spectacular twists. Additionally, Kluster DUO and Kluster can be combined for epic multiplayer games. Expert and solo versions are also available.

Please note: Kluster DUO contains strong magnets. It is a game suitable for children aged 7 and up, under adult supervision, with the necessary precautions to ensure that the magnets are not put in the mouths of younger players. Furthermore, the magnets should be kept away from devices that are sensitive to magnetic fields, such as credit cards, order books, pacemakers, etc.
