Play Magnus, a chess application for Apple iPhone and iPod Touch, and Android mobile devices by Play Magnus AS, an Oslo, Norway-based company founded by Magnus Carlsen [1], who became World Chess Champion in November 2013. Play Magnus, released in February 2014, includes a Carlsen "tuned" chess engine by Tord Romstad. Basically, it is a modified version of Glaurung with some improvements and adjustments to make its style a little more similar to Magnus', and special opening libraries for each level, based on the games Magnus played around that age [2] [3]. Play Magnus is free with in-app advertising, and offers ad-free updates with costs [4].
