Listen, yes with a slot machine you can win or lose but the amount of coins I went through to get a free spin which I need to complete the keys to the kingdom is just absolutely ridiculous. It seems like it is rigged so that you cannot win the challenges at all. I’m stuck on the last board in the Kingdom where I need 300 million won from free spins. First the spins I got paid out barely anything which is not usual for when I play the kingdom outside of this challenge and now i have easily gone though a billion coins up and down and i can not get a free spin to save my life. Sorry, I just don’t believe its coincidence that you can’t finish these challenges. I even bought coins to no avail.
