Moscow Pyramid. You Have Never Played A Game Like This.
This game stems from the Russian Pyramid branch of billiards. Typical cue sport games require that you avoid sinking the cue ball in a pocket. This is how Moscow Pyramid has become fundamentally different from any other game. The point of the game is to contact an object ball before pocketing the cue ball.
Another thing about this game is the size of the balls and pockets are different from standard pool and billiards. The balls are much larger and the pockets are much more smaller, making pocketing the ball much harder.
Now I am not saying that you should go out and buy an imported table from Russia, unless you really want to. However, this game is very entertaining. Since the game is so fundamentally different from traditional billiards and pool games, it employs very unique strategies and techniques.
