I got the app for free and did not have high expectations because of poor ratings of other users. For me it is running on the Kindle Fire HD 7 (2013) at the local games smoothly and fluently. Online I have not yet tested. The implementation of the game and I like fun. My strategy I still need to work out. Slightly more generally support would have been good. Since I had not yet played the board game were the first games a self-learning process, and I am afraid that I do not yet know all the secrets. But otherwise there 5 Star.
