About Tensioning Tensioning is where you change the force of the springs so that the cube is looser or tighter. This is a very personal thing and you will need to play with the tensions on your cube until you get the one you feel most comfortable with. When you first get your cubes it will be set up to our preference, which may not be yours. Luckily it is extremely easy to tension the puzzle cube Underneath each of the middle tiles (which can be removed with a slotted screwdriver) is a screw head. To tighten the tension on your cube screw it clockwise and to loosen turn it anticlockwise.
