The very latest online slot machine from IGT Interactive is called Natural Powers. This new IGT slot has a Female Superhero/Comic Book theme with 5 reels and 40 winning paylines and it also has ‘cascading reels’. This special feature is otherwise known as the Freefall Symbols Feature and you have to pay a little extra per spin to have this feature enabled.

In other words, instead of the lowest cost per spin being £0.40 coins, you actually have to spend £0.60 per spin. There is no way that you can avoid spending this little extra per spin, but it means that the feature is active with each spin that you take and it works as follows: After the reels have finished spinning, the line wins will be evaluated and the values will be added to the win meter.

Any winning symbols that are in view will then automatically disappear from view, triggering new symbols to fall down into their position from above. As soon as all of the empty spaces have been filled with new symbols, the reels will then be evaluated again for even more winning combinations. This cascade effect will continue until there are no more possible line wins in view.

The Wild Symbol on this new slot is really easy to identify and the only other special symbol to keep an eye out for is the Bonus Symbol. The Wild Symbol will substitute all symbols on the reels apart from the Bonus Symbol and the highest valued symbol on the reels is the Natural Powers Logo. This can award up to 4000 coins when five of them show up across any active payline.

There are five Mystery Features available on this slot and they can trigger randomly when the Freefall Symbols feature has finished. This can award WIND (which blows away all Fire and Ice Symbols away from the reels), Fire (which roasts all wind and earth symbols), EARTH (which makes random symbols leave the reels) or ICE (which freezes away random symbols). If the Super Team feature triggers and there happens to be two Bonus Symbols in view, a third Bonus Symbol will cascade into view to trigger the main Free Spins Bonus.

It is also possible to trigger the Free Spins Bonus Round when a Bonus Symbol lands in any position on reels 1, 3 and 5. When this bonus triggers, you will get to choose between four different Free Spins Modes which include 15 Free Spins with a 2X to 4X prize multiplier, 12 Free Spins with a 3X to 5X prize multiplier, 8 Free Spins with a 4X to 10X prize multiplier or 5 Free Spins with an 8X to 10X prize multiplier, it’s up to you.
