At first I was winning in the beginning and then I started losing and no matter how high or low you bid you cannot hit the big jackpot and all it does is ask you to buy coins I have did that a couple of times and still have never hit big and since I downloaded it on my phone I play everyday it's starting to suck it's like all the other games I think I just might have to find me something new to play I'm advising you not to play this game and its hard to get bonuses and free spins
