Calibration The game auto-calibrates once you hit the "go" button. The optimum setting is upright, and then tilted back naturally about 25-30 degrees. Try making sure the game is in this position before you start, then see how the accelerometer works if you're having trouble. Remember, the game actually requires 'learning' and developing the hand-eye coordination, which you will after a few levels. Also, on the bottom right is a "tilt" control, this will Invert the up/down axis. You may find it more natural to do this.
