A basket-like box intended to contain elements for a game which requires a black-board, the black-board also serving as a cover for the box, and this latter on its turn serving as a support for keeping the black-board in a working position. To the rear part of the box there are sideways pivoted the end portions of two levers, to the opposite end portions of which is pivoted the black-board, whereby when the black-board is lowered it places itself onto the opening edge of the box, thus forming the cover thereof, whereas the raised black-board rests onto the box edge, and it is kept in working position. The upper side edges of the box are shaped with a series of teeth which enable obtaining different stable working positions of the black-board resting on said teeth. The front end portions of the levers are provided with spring latches suitable for co-operating with stops of the box edges in order to keep the black-board in its position of closed cover until said latches are opened in order to allow opening the box. The black-board can be overturned for being exploited on both its faces.
