Hello everyone. I am new to this site but thought I would chime in. My high score on the LE model is 143M. The gem shot is near impossible if the ball is hugging the flipper or moving too fast. I make the shot by shooting the Quorra loop at a reduced speed(quick tap of right flipper), then when the ball comes around to the upper left flipper doing a quick double tap first tap to get separation second for the shot. It gets easier with practice, but the ball has to be traveling slow. A very difficult shot for sure. As far as strategy I find it best to try and combine Quorra and Light Cycle multiballs then quickly knock down TRON targets for double scoring. I concentrate on completing Daft Punk for extra ball and End Of Line multiball and let everything else work itself out.
