How do you beat level 22 on red remover touch

First tap the 2 lowest half red/half white blocks (without faces). Then tap the highest half red/half white block, this will cause the heavy red block to push the light red and green blocks dropping the green block to safety. Then tap the remaining 2 lighter red pieces (one with a face the other half red/half white). Finally, tap the farthest right blue block, the red blocks will drop causing them to fall off the screen and the green block will flip around landing safely on the other blue block!
