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 third chapter is Alex's Bedroom. These 32 stages add a number of new toys. There's the remote control truck, the (familiar) green piggy bank, the floaty paper aeroplane, and the magic magnet. There's also a ragdoll, but we're going to assume that belong to Alex's sister.
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.
