the trick with most of the games is dont try too hard, you can do just as good by making swift movements. It also comes down to how straight your swing is, look at the indicator once you have had a swing and it tells you the direction the balls gone in.... same for bowling, which is the 1 i cant get the ball to go dead straight..
The best game ive played so far on it is a new version of duck hunt, mix's the old school duck hunt & clay shooting game together.
