Different outcomes for Blender Game animation

Hello guys,

I tried to create a marble run in Blender.

But every time I use Blender Game + “P” the seesaw at the the end of the track shoots the ball differently. Sometimes the ball (red) is to low or to high to reach the blue box (red marked):


How can I find a solution that the ball always flies in the same direction and height?

Please see my file attached:

Many thanks for answers!

Can someone help me please? :slight_smile:
