our mission

bringing free-to-play MMOs to mobile to allow players to join the adventure wherever they are


One Thumb Mobile is an independent mobile MMO game developer located in Scotland. Founded in 2006, our mission is to bring genre defining MMORPGs to mobile devices and tablets. Our team boasts some of the best talent in the game industry, combining an unparalleled mobile heritage with MMO expertise from the world’s most popular online games. We think a creative, inspiring work environment is paramount, which is why we are located within a beautiful listed building in the heart of Glasgow’s arts district, just off Buchanan Street and only a few minutes’ walk from both Queen Street and Glasgow Central stations.
At One Thumb Mobile, we are experts in managing complex, technically challenging, multi-faceted projects, having previously worked for brands such as VISA, Honda and Liverpool FC. With our proprietary platform, Celtic Heroes was one of the first ever mobile MMO titles to embrace in-app purchasing and pioneered the launch of a secondary trading economy on mobile. With 90% of items tradable in Celtic Heroes, we are also true advocates of free-to-play gaming. We are 100% independent, successful, profitable and growing rapidly.
