Ok, I have construct the logic behind the balls disposal/regeneration.
Now when a ball touch the entry point of the flippers, a timer of one second activate a function to
bring the ball at a random location at the top.

See it in the link, first post.

You are a magician Steve !

It improves very well. You give me some ideas to try it with three.js / ammo.js... grrrr but I need time, time time !!!

Thx for all the data backup.

Script update for now, A lot of clean up. I have clamped velocity of the balls to a MAX speed of 20px per second. because sometime multiple collisions at the same time tend to build up speed and the balls were ejected out of the table.

Also left and right lane : invisible sensors now create friction so the balls are slowed down toward the flippers.

The text box on the right are just to monitor the velocity. @backup you can watch more data in the console.log.
