I find when I am in Vegas, I always try and give Aria and the Riviera a few of my dollars. However, I've had the best luck (lately), gambling at Bally's, NY NY and Monte Carlo. Bally's has always given me money on their penny slots and NY NY on their dollar slots. In passing, the Monte Carlo penny slots have been kind if I do not stay longer than 15 minutes. Oops, I forgot Ceaser's - well I didn't count them because I've only gambled here once and kept winning on the penny slots. I believe I started out with $5 and left with over $300 (I think this happened or I could have gotten $300 after visiting several hotels in route to Aria.
