The Loaded slot will appeal to free spin slot players - in theory anyway. Myself, I never really liked the theme, but I must say that it is very playable and you get to choose your free spins bonus when 3 or more scatters appear in view. The only real downside is the lack of retriggers, but otherwise they aren't too difficult to hit. Actually when Loaded first came out, some online casinos thought it was a bit "un-PC" and decided not to carry it. Then when it suddenly jumped into the Top 5 most popular slots, suddenly everyone had it...strange that, eh ;-)

If you like Microgaming slots like Loaded, there are a few others here at OCV that you might like to try. The cool Hellboy slot is one of the more recent additions as I write (Feb 2010) although IMO you can't beat the olden-but-golden grandfather of free spins, the Thunderstruck slot which will take a lot of beating!
