I play on FOBTs, but strictly category B3 only. Same category as arcade machines.
I like Imperial Dragon (obviously my user name), Thai Flower and most other Barcrests (Monty’s Millions, Star Wars, Ooh Aah Dracula etc). Having said that, I’ve never got on very well with Rainbow Riches! Outside of Barcrest, I like Reel King.
My least favourite slot is Eye of Horus. The Bandit plays a similar / clone of this online. Can’t remember what it’s called – Pharaoh’s [something].
