We have Russian billiards (2 tables) and American billiards (1 table).
The game is a peculiar one.
On the one hand, it's a sport game. It requires skill, special skills, reaction, sharpness of movements and cue hits. On the other hand, this is an intellectual game. It requires a clear view, the ability to calculate the game for several steps forward. The game is interesting because it has no age and gender restrictions.
Enjoy your game!
