The list of UCI and XBoard engines for Android is getting longer, and I am pondering about a more serious tournament at longer time controls in Chess for Android . As a first step, I tested all available Android binaries. The list is shown below. An "X" indicates that the engine has trouble running in Chess for Android (if you are the engine author and are interested in fixing this, please contact me for details). Next, I probably do a few quick tournaments to divide the engine in groups by strength, followed by tournaments at longer time control. Please feel free to contact me if you are interested in participating, if you don't know how to compile your engine for Android (ARM), or if you have good ideas about the format of this tournament. I am not really an experienced tournament manager, but merely do this for fun to get an idea of the relative strength of these engines. apilchess-106-ja X U. Lorenz, C. Donninger bikjump1.8 Aar
