One strategy for Amazing Alex The Backyard level 2-14, called “Back & Forth”, is to angle the shelf downward to direct the 8-ball into the green pail. Have the scissors positioned to cut the rope as the pail swings rightward. The 8-ball should start rolling left after hitting the pail. Angle one pipe to obtain the second star, then another pipe to direct it back to the right to get the third star on the ground.
