I asked Elizabeth to explain a little more about the Trick Volo competition and she provided this...
" In the Trick Volo competition there were 4 events. You only had 1 attempt at each event. The 1st one was where you had to hit the target raffa ball behind another raffa ball set where the pallino is placed at the beginning of each game. It is a rather long volo shot.
The 2nd event is where someone banks the moving target ball off the left side wall, then you can shoot at it once it passes the volo line. Remember it is a moving target at a diagonal angle.
The 3rd is against the right side wall.
The 4th event is where 2 people roll distracting balls diagonally while a 3rd person launches the target ball directly. You can only shoot at your target after the other 2 balls have crossed each other. As you well know that it is difficult to focus on a stationary target, let alone a moving one, then to top it off, you have the 2 distracting balls that you must keep an eye on."
