A quick release mechanism is provided for a game machine chair. The chair is securely mounted to a planar base having a front edge. The game machine is provided with a downwardly opening locking channel with a front wall that faces the chair. Tapered structures on the base and/or on the locking channel cooperate to align the base with the locking channel. The base further includes a locking aperture or a locking projection near the front edge of the base. A latch is trapped in a latch cavity of the locking channel. Forward sliding movement of the base on the floor causes the front edge of the base to engage the latch. These sliding forces will lift the latch sufficiently for the latch to align with the locking aperture or projection on the base. This engagement holds the base and the chair in fixed relationship to the gaming machine. A key way is provided in the locking channel and is accessible by a key to disengage the latch from the base to enable the worker to access the machine.
