Just got back from a five night stay at Four Queens and had good luck on both machines equally. Got 56 strikes for $500. Mostly because I got lucky on one twenty dollar bill and got 12 strikes. I don't like putting in a hundred because I swear the machine knows it and doesn't give you anything for at least the first $40-$60. I also had good luck on the 3 line machine at the Palms by playing just one quarter at a time. I got 3 strikes for one quarter. Overall got a bakers dozen strikes for $125. At the four Queens I also saw 2 people hit double diamond-double diamond-double diamond for a nice little $500 payout. I have never hit that but I also saw someone hit it at the Palms on the one line machine. My brother didn't have very good luck playing the machines at Sam's Town and we never made it to Planet Hollywood this trip. Good luck.
