I must admit the adds are annoying but that is not to much of a problem so yeah. As far as free chess games with some standpoint of quality go I am pretty happy with this app, only problem I have with it is how it costs game money to redo a turn. I think there should be two modes one with free redos but it won't go towards level status and one with no red's but it counts towards the level status. Other than that good game and keep updating it.
