The present invention is directed to a portable, collapsible enclosure for use with a portable game console or computer for playing video games on a large screen television where the game involves tracking the position and movement of a moving object. The enclosure has a fabric cover and a frame which is movable between a collapsed position whereby the enclosure may be easily stored and an expanded position for playing a game. The fabric cover of the enclosure in the expanded position has an open front, side and top walls and a rear wall. The rear wall is provided as a netting material which is selected to arrest the movement of a moving object projected into the enclosure through the open front, while permitting a user to observe an image displayed on a large screen television placed to the rear or side of the enclosure.
