There are two versions of the "Wheel Of Fortune" slot available, both based on the gameshow of the same name.
The free play version above is not actually the IGT version, but fairly similar as you'd expect.
This version is dubbed "Triple Action Frenzy" (the other is the "Hollywood Edition")
and available to play online at the Wagerworks casinos listed above (no US players however). It's called "Triple Action" because
of the way the feature works. There is also a "Wild" symbol which can muliply wins by up to 5x, and the feature
itself is a pick 'em bonus round triggered by 3 adjacent "Triple Action Bonus" symbols which leads to the spinning the Wheel
Of Fortune.
Both online versions of the Wheel Of Fortune slot have very good expected payout percentages. This version is the best
weighing in at 97% across the board, irresepective of whether you are playing for fun or for real money.
The Hollywood Edition of Wheel Of Fortune has a slightly lower
96% setting, but even that is better than average for online slot games.
For USA players (who can't play this game for real online) it is worth noting that Microgaming have
developed a similar'ish game called "Wheel Of Wealth", which you can play for free or for real. Go to
the Wheel Of Wealth page and have a spin or try some of the
other excellent IGT slots on the site.
