A separable assembly includes a cellulose member having a side surface and an end face forming an edge with the side surface. The cellulose member defines an elongated sliding track that extends from an end opening at the end face and has a T-shaped transverse cross-section. The cellulose member defines a side opening along the sliding track at the side surface of the cellulose member. The sliding track further defines a detent recess spaced from the end surface and extending into the cellulose member. The separable assembly includes a rigid plastic member having an edge configured to be received within the end opening of the cellulose member and slid along the sliding track with the plastic member extending through the side opening. The plastic member includes a detent protrusion configured to engage the detent recess.

A part includes a fastening system for fastening to another part so as to form all or part of a ball game board, the part including a plurality of cavities arranged in a two-dimensional ordered array on a first surface of the part, each cavity being designed to receive a ball, the part including a device for reversible fastening to another similar part along a fastening border, wherein the fastening system is formed by a plurality of overhangs each including at least one cavity of the plurality of cavities; and a plurality of indentations designed to receive the overhangs from another similar part.

A modular gaming apparatus allows for board games such as chess to be played on one or more levels. A base structure include a drawer and a fixed game board, with one or more playing units being provided for stacking atop the base structure. Each playing unit includes a game board, legs, and a track mechanism that allows the game board to slide out for easier player access. A virtual game piece generating unit is also provided, the virtual game piece generating unit allowing for non-physical representations of game pieces to be created. A computing system allows for pairing of electronic devices and processing by means of a processing module and a communications module. The electronic components control the virtual game piece generating unit and also allow for remote play.
