Poor gameplay experience. The number of times you "win" is actually a little higher than some other slot games, but it doesn't matter at all if it costs you $20 million in chips to make 1,000 spins to win 100 times at only $5-10k each win. The only reason I'm still able to play is because of the free daily bonuses in the morning. I just save those up for a couple days and then I get to roll for another 5 minutes before going broke again.
