The machines at Buffalo Bills are the loosest compared to Whiskey Petes and Primm Valley, but the rooms here are not as good as the newly renovated ones at Whiskey's. What I like to do is stay at Whiskey's and play at Buffalo Bills. They have a 24 hour shuttle and on the weekends, their monorail is open for easy access between casinos. The Denny's restaurant is better and the cocktail waitresses are friendlier.
