31X Ltd was formed by Chris Sawyer in 2010 to develop Transport Tycoon for the new generation of mobile platforms.

Developed by British programmer Chris Sawyer, Transport Tycoon on PC was one of the most fun business strategy games ever made. The original game was published by Microprose in 1994 and helped introduce game players to “mouse” interaction on the PC.

Chris also developed RollerCoaster Tycoon, released through Hasbro Interactive early in 1999, followed by two add-on packs late 1999 and September 2000. RollerCoaster Tycoon 2 was released through Infogrames in 2002 followed by RollerCoaster Tycoon 3 in 2004. Games in the RollerCoaster Tycoon series were the largest selling simulators before the Sims games on PC.

Now Transport Tycoon has been digitally re-mastered for mobile platforms for Tycoon lovers across the world and moving this renowned and well-loved franchise from mouse touch to finger touch. Available now on iPhone, iPad and other touch-screen platforms.
