Kinect Sports

Select "Table Tennis" from Main Event menu and choose to play against a computer opponent. Select "Beginner" difficulty for the computer opponent to make this easy.

After the match starts, stretch out either arm to select left-handed or right-handed. I played the first match with my weak hand first to get that over with. Take your time and swing a little early (to account for slight Kinect delay). If you have played table tennis for real, the Kinect sensor can detect if you put top-spin or back-spin on the ball (evident by the yellow or blue trails around the ball, respectively). And don't forget to move around your play space because you can come up short on hitting the ball if you are not in the right position!! Play to 11 points to win. Achievement unlocked!
