You move your tiny avatar by dragging your finger where you want him to go. On the ground are color coordinated switches that correspond with the colored forcefields; obviously, you need to push a box on the red switch to make the red forcefield go away. You can’t pull the boxes so if you shove one into a corner you can't get it out which adds a little difficulty to the game. Once you have moved all the appropriate boxes, deactivated the forcefields, and collected all the gears you are ready to move on to the next level.
Overall it’s a good solid puzzle game and it’s challenging enough to be fun without me wanting to throw my iPhone on the ground and stomping on it. Thank goodness too because I don’t think I can afford another iPhone. I’m giving Boxed In 4 over worked robots out of 5.
Oh yeah, the full version is free for a limited time so I would download it ASAP.
