Game History

With over 100,000 original copies sold and over 500,000 players in the former Soviet Union, CTOR is a revolution unlike any other seen in the last two millennia. A member family of logic and thinking games, CTOR’s closest relatives are Chess and Go, a Chinese thinking game invented over 2000 years ago.

The inventor of CTOR, Dr. Vladimir Bronn, is one of the world’s most intellectual and unique individuals. Dr. Bronn exhibits an unparalleled passion and drive for mathematics and logic. A pioneer of artificial intelligence, Dr. Bronn’s CTOR represents the next great leap forward in the evolution of human intelligence and logical thinking.

Puzzling over the physical limitation of boundary conditions, Dr. Bronn’s eureka moment came when examining an ancient Mayan board game. This ancient game, when visualized in a particular way, is actually a Tor. A tor is a unique shape, similar to a bagel, with no physical boundaries. This realization led to the creation of the phenomenon known as CTOR.
