I had a dream one night that I invented a billiards table with no holes on the sides or corners. Only a hole in the middle of the table.
The object of the game was to sink all your opponents balls into the middle hole before your opponent could sink his in.
Getting the cue ball in the middle hole resulted in a forfeit of the game to your opponent.
The game became a big hit.
I must have had the same dream, because one day I put a hole in the center of my pool table (well, not dead center). But I did it so I would have another hole to aim for.
Note: Table top was not made of slate. 🤣
