Screw Bolts 3D

You need to use your brain for this, can't just randomly twist screws.

It was easy at first, but it gets pretty difficult later on. Otherwise, it's really not easy to pass later.

The 3D graphics are beautiful, but the game itself only offers two free color screw slots. You have to use items or watch ads to open a slot for each level, and you even need to open up to the 4th slot.
