I don't usually like playing slots but if I go to a brick and mortar casino with friends looking for fun and they venture over to the slots I will play some. The only one I like playing is the wheel of fortune slot. I don't like the slots with so many things going on that I don't even know what it takes to win at. And the wheel of fortune one brings back memories, I always play hoping to get to spin the wheel. Seems to pay out more than the others too.
Every gambler has his individual preference to different games for their different reasons. This reason differ from difficulty to luck to even wagers. So gamblers prefer games like sports predictions where luck has a greater advantage. Some others prefer casino games where analysis and experience has a greater advantage.
Sometimes the casino it self can also contribute to how much interest their users put into some of their certain games. In some casinos the wheel of fortune slots has bigger and fancier wagers while in some the odds and benefits aren't very attractive.
