Gameplay is easy, automatic matching is very fair, ratings are done well, and there are plenty of features that make playing and FINISHING games easier/more enjoyable. Those features include automatic reconnection to game if you disconnect (d/c) due to reception or whatever (even if app crashes which has never happened to me), automatic win if your opponent d/c’s and doesn’t return, automatic game time limits, and no options to abandon game (only options = resignation, timeout, or d/c loss ...or win of course). Your opening techniques, stats, and game records are all saved for easy review of games. This is especially nice since you get a “password” assigned that you can use on other devices to automatically load your account for play across multiple devices. There’s a problem set for study. You can even enter tournaments. Plus, the ads aren’t even very disruptive. The one downside that prevents me from giving 5 stars is that there’s no decent helpfile to explain little things, like “why are different usernames different colors,” or “why is some text green and some black or grey on my records page.” What does that stuff mean? That would basically make this the perfect reversi app.
I definitely recommend it!
P.S. FYI, there’s no chatting.
