Abstract: A universally attachable tray assembly adapted to be secured to table edges of various configurations including on the surface thereof a set of instructions regarding a particular card game, chip recesses for storing betting chips and a drink recess. The underside of the tray is provided with an orthogonal mounting surface arranged as a rectangular strip extending transversely across the tray bottom, the rectangular strip including a plurality of vertical slots formed therein for receiving securing fixtures. The vertical slots are separated by a dimension equal to the dimension separating a plurality of screw holes and slots formed in the surfaces of an angulated mounting bracket which may thus be secured in any angular arrangement to adapt to the edge configuration of the table.
