Good game but.... too many grossly intrusive third party ads. High roller slots are rip offs. I accumulated enough to play one and immediately lost 400 million coins. After going back to regular I accumulated 3.4 Trillion coins, back to high roller and immediately lost 400 BILLION coins. The more you bet, the slower the features come around. Per line payout schedule is far lower in features than in base game. Some features the high paying symbols are removed.
