  • Patent number: 6375191
    Abstract: The present invention relates to a snooker table (10) having a conventional rectangular outer frame opposed major sides (12, 14) and minor sides (16, 18). The playing surface (20) is non-rectangular, in that a pair of arrowhead or ‘V’ shaped projections (22, 24) extend inwardly from respective major sides (12, 14). The playing surface (20) thus has an hour glass-type shape, and is bounded by a conventional cushion (26). Pockets are provided at opposite corners of the table, as in conventional snooker table. The projections (22, 24) terminate in similar pockets (30A, 30B), which are located along the same center line as the middle pockets of a standard snooker table, but which are spaced inwardly relative thereto. The snooker table provides for a snooker type game which is both versatile and challenging.
