Free spins can be considered a rather standard practice when it comes to bonus rounds in slot gameplay. Nevertheless, providers are getting more and more creative and innovative these days, with some including a separate in-game round with a challenge or goal that need to be achieved in order to win. Some include both these rewarding features, like the massively successful progressive jackpot release from Microgaming which features both a free spins bonus, and a bonus game with a spinning wheel in the Wheel of Fortune style. Different-colored segments of the wheel are for the different progressive jackpots. The slot in question is Mega Moolah and a quick search through Microgaming’s portfolio should see you testing it out for yourself within the minute.
