I just took a look at it.
Way more books on the reels than on regular Book of Ra, but the paytable lol
Normal book of Ra pays 2.5 times the amount for any win compared to this slot. There must be a lot more high symbols on the reels as well, has to be a lot less volatile than Book of Ra Deluxe. Give more features I assume and lower wins in them , which isn’t necessarily a bad thing, always nice to get some features
