It's quite simple.

 It's gambling and also a sustainable system to end up getting your prize.

 1. Focus on Lucky Seats. Whenever you buy a seat in entry level, each person has 25% of getting the prize. It increases to 50% in HAPPY Hours that occurs randomly.


 2. First in First Out. So if you didn't had luck getting instant reward you go into a queue line along with others that didn't won. Each person will get a unique queue number. For every time there isn't a winner in Entry Level with Lucky Seat the line keeps moving forward until you get number 1 and get paid. Can take a while, but at least you know you didn't lost everything Patience - Hodler!
