Making a Ball conveyor system

[InfinityPlayer]

I have attempted to copy of the ball machines i've found using the search on Algodoo.com, but i haven't been able to get the balls to go back to the top and start all over again. Is there someone who can tell me, or perhaps give me some suggestions on how i can do this.

Thanks in advance

You can use a convener belt sort of system like shown in the attachment.
