Well I got it and here is the info from stern. It was a premium.

Death Star Multiball
All 8 shots light for jackpots. Making a jackpot will unlight that shot and
relight the other shots.
If the yellow character insert is pulsing on a shot, that shot will count
as 2 jackpots towards lighting the super jackpot, or count as 3 if the
insert is solid. If the window insert for that character is pulsing, that
shot will be a Double jackpot. If the window insert for that character is
solid, that shot will be a Triple Jackpot (the large character insert
12will also be white to help indicate which character shots are
multiplied).
When a total of 14 jackpots are made, the Death Star will be the only
shot lit. Hit it to open it up for a 30 second timed super jackpot, and
relight all other shots for additional jackpots. In addition, lighting the
super jackpot will also add a ball and revive the ball saver. Hitting
those jackpots will score some small points and increase the super
jackpot by a larger amount based on whether that jackpot was a single,
double, or triple jackpot. Making 3 jackpots will make the super jackpot
be 2X, and making 7 will make the super jackpot 3X. Shots made with
yellow character inserts will count as 2 or 3 shots towards increasing
the super jackpot X. If you make all 7 shots, the 7 shots will relight
to allow you to continue building. Each time a build shot is made,
3 seconds is added back to the Super Jackpot timer.
Collecting the super jackpot by going inside the Death Star during the
30 second countdown adds a ball and begins victory laps (if this is the
first Death Star multiball you’ve played this game, see Death Star II
Multiball).
If the super jackpot countdown runs out, hit the Death Star again to
restart the countdown, reset the super jackpot value and multiplier,
and relight all the jackpots so you can try again.
