How many elite lock boxes do you open to get your first jackpot ?

I have opened about 50 boxes , none yet ?
Also what are the methods of getting jackpot beside lockboxes?
I dont wanna make a new thread but information on this game is really scarce so guess i gotta ask for myself.
Thanks for any information provided !

I didn't find the right solution from the Internet.
