Bouncing Ball

craps

I have a ball that drops and when it collides with one of the four walls around the scene it bounces. Works fine. But over a short period of time - no matter what random bounce the ball takes - it slows down and always ends up in the bottom right corner.

I would like the ball to bounce continually random until the user touches it. ( Yeah I have the touch rule working too)

Thanks

How do I make a "random" bouncing ball?
Like the following example
