Does anyone know the solution to 1-28 in puzzle mode

First: Swap the gray ball changer to a green ball.
Second: Place a green ball on the left side of the lower/center chain.
Third: Swap the gray ball changer to a green ball.
Fourth: Place the green ball on the bottom of the right most chain.
Fifth: Turn the green balls gray with the gray ball changer.
Sixth: Turn the gray balls red with the red ball changer.

From here on out you just need to go through and complete the screen with the red balls. The top most chain will combine with the left most chain when you knock out the center red two balls.

if you get to seventeen good luck i was on it for 17 weeks i suck
