For this achievement you must Start a Multiball Phenomenon with the cube on Paranormal! (Single player only.)
First, have a good look at the entire Paranormal table. Notice towards the right above the ball launch there is a picture of two film reels and then an interactive one as well with the title "lock" just below. This is where you'll lock your balls. If you pass a ball through it's loop it will cause it to rotate leaving the two opposing sections vulnerable and "lock" will be lit. In order to get the ball there for a lock/rotation I found it easy to hit the very center orbit bringing the ball to the right ready to meet the top right flipper. Using the flipper send the ball to the left immediately into the blue sink hole titled jackpot. Doing this will shoot the ball randomly and sometimes but very often straight into the lock you are going for.
Once you have at least one ball locked you will be required to rotate the cube using (LT)(RT) and (A) for select in order to chose a mini game. I chose the side with one hole titled Levitation. Send a ball up the right ramp and be prepared to send it to the right again with the top left flipper. You will then have a few seconds to regain orientation. Using (LT)(RT) for the pistons will decide where the ball drops into the hole on the cube so be careful. Basically just wait until the ball passes over the hole and use the corresponding piston to send it down the correct path. Some sides of the cube have angled paths leading the ball away from the hole so be aware of that. If your unsuccessful with the first attempt you do have a second chance. Simply put the ball in the hole on the cube and multiball mode will activate.
