Unless you have a ridiculous amount of money burning a hole in your pocket and want to get rid of it without getting much in return I would not bother. the amount of pop ups and adds are so bad that it can crash the app. it seems every 10 spins something pops up to try and get you to spend real money. the prices of these are insane and the reward is insignificant. not to mention, the games and bonuses are so rigged. it doesn't want you to win. Just win enough so you want to keep trying.

Just know you have zero control over winnings. Example - I started a quest 4 days ago. I had to get a specific amount in free game winnings to past the quest. 3 days ago, I reached 70% complete. 3 days later and over 1 quadrillion coins later, I am still at 70% complete. I have not achieved a single free spin in 3 days (and over 8 hours of playing). They will tell you to come back later if you can't get free games. They control when and what you win... especially if you don't pay them enough.

good payouts no adds. it's very annoying when I'm playing a game and tries to force sell you coins, packs, passes; when I'm in the middle of a game and have to bash the X to decline. there's plenty of ways to get coins without paying for them. and constant crashing when you have luck. I don't pay for passes or upgrades on any game never will.
