Shoot a ball into each pocket to get a trophy. Collect each trophy to activate the goal. There is no ref to return the ball so if you put the white in you have to start again - it's the final goal. Shoot to move them but be careful they can go fast. Don't fall in the pockets.
Hint - you can make them move slowly by standing near and hitting the edges. If you keep hitting the pack eventually something will go in.
Thanks for the feature, should have said initial idea was inspired from @per and pinball wizard
