Zen Table Tennis is a simple table tennis app for Android phones. The app is obviously not meant to be a complete experience but more provides a quick game to fill some extra time. The game offers two different difficulties, Easy and Hard, to choose from. Aside from that, there really isn't much more to it.
Your paddle is controlled by your finger. As the ball comes toward you, you will need to hit it back. I found that swinging too hard will cause the paddle to fly right through the ball which got annoying at times, so the best way is definitely to just block or swing slowly. There aren't any more options to choose from. Games are played and won by the player who reaches 11 points first. The graphics of the game are decent but nothing to rave about. Many times in the game it lagged and lost the point for me.
Overall, the game was fun and simple but didn't offer much more than a quick break from what I was doing. The price being asked in the app store is somewhat ridiculous for what you are getting, so I definitely suggest grabbing the lite version before plopping down the money for the full version.
