The game is designed to encourage players to constantly buy boosters so they can win. It's possible to play & win for free but the "random" matching is more a does the system choose to randomly let you win or lose. One player seems to usually have all the right pieces falling into place sometimes its you often its not. If everything is random maybe they need to adjust so that people have a fair playing ground. I'm not paying for any more upgrades until they make the games more fair.
