Yes, it fails on two counts. Primarily the RTP is shocking, you can lose money on the feature as has ben stated!
Basically on average 92% RTP gives you only 57% of the spins per deposit you'd get from a 96%RTP game.
And then the game is tedious shite too. One crap feature over in a minute.
The thing is this game has been plucked from land-based slots in the USA and has land-based RTP. Playing it at home online shouldn't mean you should be paying 2% for security guards, waitresses and free rooms....
