Russian Pyramid billiards, also known simply as "Pyramid," is a form of billiards distinguished by its high degree of difficulty and its focus on strategy and precision. Popular primarily in Russia and the countries of the former Soviet Union, this sport offers a unique playing experience, distinct from more widely known variants like American pool or snooker. With larger, heavier balls and pockets only slightly wider than the balls themselves, Russian Pyramid is a true test of skill for any billiards enthusiast.

5-Pins billiards, a modality that combines classic carom with the knocking down of small pins, stands as a fascinating game of precision, sharp strategy, and a rich history that extends across Europe and South America. Also known as Italian billiards, this sport demands from its practitioners not only a refined technique and a deep understanding of table geometry but also a calculating mind capable of anticipating plays and constantly weighing the relationship between attack and defense.
