I have 2 boosters activated, not enough rubues to upgrade anymore, doing it as fast as I can and still lose, because it gets 1.1k instead of 1.2k, or runs out of time when u get 4x3 complex orders so u have no time to finish it, I even use time freezers a lot and still: impossible to win after a certain time if you don't pay real money to get rubies and upgrade.... Im done with this game.
