for 17 par - it takes a bit of proper timing... I got it consistently by taking the big circle and little circle (again, watch for timing) so that the 2 reds roll down and knock back and forth with the left one... they'll go back and forth, and you'll have two blues facing right with one red from bottom still there if done properly. Click the blue touching the red to get the red to roll away... then do the same thing to the top right - click the two big blues touching the little one, then the little one pretty quickly so the circles don't stop moving - that's 6 clicks ;)
