I have never been lucky and my first time at the Hard Rock Casino in Sioux City, IA I won 1000. I really enjoy this casino and recently went back and won 2540 on the Price is Right slot machine. I went down in the morning and within 45 minutes I had won 1756.00 cashed out and started over with 100.00 in machine. Won 784.00. Needless to say I should of cashed out but the thrill of winning kept me playing and machine went cold. Ended up throwing all my winnings back in. I still had a nice time plus the room was free for the 2 night stay. Can't wait till I can afford to go back. My favorite casino so far.
