Amazing Alex: 3-star level walkthroughs for The Treehouse

Meet Amazing Alex - a creative kid who likes to make barmy contraptions out of toys and other things he finds lying about the house. In this physics-puzzler, it's your job to slot in the missing pieces to make his chain reactions come to life.

The fourth chapter is The Treehouse. These 32 stages take place in Alex's backyard getaway, and introduce a few new toys. We get to play with the bouncy ball, the remote control helicopter, and the zip wire.

If you get stuck, load up the level fresh and then recreate the setups shown in our screenshot walkthroughs. If you follow our advice to the letter, you'll beat the stage and unlock three stars on every level.
