Amazing Alex Level 3 for Week 1 (October 16) is called “Two Cylinder”. This one is a bit challenging. Use one of the scales to angle the marble to the left, toppling the books onto the switch. This will cause the 8-ball to fall. Angle it leftward using the pinball bumper, knocking it through the left cylinder to obtain the star there. Angle both the 8-ball and marble rightward, so the 8-ball hits the scissors on the right side to release the balloon.

Well, I know I did this one differently, but since your solutions disappear once you start a new level, I can’t provide details.
