For those of you who frequent land-based casinos either here in the UK or over in Vegas, you'll probably need no introduction to the Cleopatra slot which, along with the Book of Ra slot and IGT's IGT Pharaohs Fortune, is now a permanent fixture at just about every land based casino in the UK and beyond. I've played the Cleopatra slot machine recently at Rendezvous casino in Brighton and at The Empire Casino in London, although there is a marked difference between the online version and the land-based version. The payouts in the online Cleopatra slot have a 95.01% return online eclipsing the version(s) in land based casinos.
The main reason for the better payouts online is that two 9's pay - in fact there are two versions of the Cleopatra slot machine in land casinos too - the "sit-down" version doesn't pay on two scatters making it even worse than the kiosk version. The online version of the Cleopatra slot machine pays on 2 scatters aswell as 2 9's which adds to the expected return, most notably in the free spins bonus round. Hope that made sense - bottom line is this version is potentially more friendly ;-)
Also worth noting that you can now play Wolf Run here at GFM (along with various other IGT fruit machines).
If you would like to see some videos of not only the Cleopatra slot machine (online version) but also a number of other popular slot games, each of which shows the bonus feature in full swing, then check out the IGT Slots website which as the name suggests, deals with online slot machines manufactured by IGT.
