About this game

Experience the revolution that is CTOR.

CTOR is a mobile strategy game in the same family as Chess and GO, with over 400 million possible moves! CTOR was developed in the former soviet union by a brilliant scientist who is also a pioneer of artificial intelligence.

CTOR is chess, made new for 2019! A game that swept the world over 1000 years ago finally has a modern competitor!

Using mathematical principles developed by the game’s creator Dr. Vladimir Bronnikov, CTOR emulates mathematical biology within an infinite world space. The game board is a mathematical representation of a unique shape known as a torus. A torus is similar in shape to a bagel or doughnut. If one were to walk on the surface of a doughnut in a straight line, they would walk virtually forever. When you play CTOR your brain experiences no limits!

CTOR trains both the left (logical) and right sides (creative) of your brain - get smarter and have fun doing it.

Originally a board game, CTOR has been developer for mobile phones for the first time in history! Over 100,000 original copies of this game have been sold and enjoyed since 1988.
