My overall thoughts: A lot of penny machines, many I didn't write down but it seems that's the demographic they are targeting to get people into the casino or keep them playing. In terms of the 1 line machines they don't have many. The $1 Pinball or Top Dollar could be something I could see myself playing if I can make a 2 or 3-credit bet with a $200 bankroll. The five line machines unfortunately I would have to work my way up to I would think as $5 a spin is a bit steep for me at the moment. My best ones would be for the $0.25 machines of Black Diamond, Crystal Star, or maybe one of the Blazing 7 machines I have listed. In terms of penny machines, I've seen people win big on the Mayan Chief Boosted Great Stacks and a similar kind for China Shores. They also have regular Mayan Chief and China Shores I could bet 3x for $0.90 though for those it seems you want to hit the feature with more than 15 spins as that's where it gets lucrative. I'm a fan of the Wicked Wheel games as they seem to pay steadily though curious about other's thoughts on the vitality. Might Double Chili Mania Respin be worth it? Saw Cowboy play it. I played it without too much action on it.
I don't know how low the Cash Express Luxury Line Buffalo or Big Fu Cash Bats Dragon are but those might be worth a shot. My dad played last time on a wheel-type machine (see photo). His thought is to play $20 plus $20 in free play for 30 spins at $2.25 a spin to see if I win anything. He came away with $400 last weekend. 
I feel like overall someone let me know that the denominations at this casino favor low rollers or high rollers. More variety in penny machines but I am not sure about the volatility. Any insights with a budget of either $100 or $200 feel free to comment as I'm curious about what thoughts/takeaways I missed.
