The RNG and luck is just such a lazy implementation, though they probably only do it for money they do a bad job at hiding it. This game is also rigged and when it shows you have a 50% chance of stealing a gem you actually have a less then 40% chance of stealing a gem. It's even worse when you try to retrieve your gem, you secretly have less than a 15% chance of retrieving it. The orbs are just pay to win and it trys to scam you for free 'orbs'. Never have a uninstalled a game this fast.
