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, 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 Tor. A Tor is similar in shape to a bagel or a doughnut. If one were to walk on the surface of a doughnut in a straight line in any direction, they would walk virtually forever. When you play CTOR, your brain experiences no limits!

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

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

- Test your brain in single player to see if you are a logical or creative thinker.
- Train the less dominant part of your brain to increase your problem-solving skills!

“CTOR is very helpful in terms of the popularization of mathematical biology and the development of a player’s thinking process” — Scientific American

“Brain study is one of the biggest challenges of our days. CTOR, a game based on a deep understanding of the human thinking process. Strategies in this game are much more diverse than those of traditional strategy games like Chess or Go” — PC Week

CTOR it's fun once you get it

This game is actually really good!

I looked it up online and it's some kind of mathematical thing where the game board is a 2d representation of a shape, but the shape is similar to a bagel.

It makes sense because if you were to walk on a bagel you would walk forever in a straight line without ever falling off of it

So this game actually makes your brain think. I played it in single player for about half a hour and it made sense after about 10 or so minutes. The only reason I stopped is because I had to go to work.

I could actually feel myself finding ways of playing the game. The game claims to have over 400 million moves and honestly I believe it. I could play it for hours and each time it would be a different game.

With CTOR I don't think I'll ever get bored of playing it!
