The jungle pyramids of central America are the setting for Aztec Power, a 5 reel, 25 payline slot from Novomatic. This historical adventure comes with a feature that awards 20 free spins complete with a Power Line extra that can boost bonus feature payouts with a dynamic multiplier. Stakes range from between 50p and £50 per spin.

Overlooked by mountains and a threatening night sky, the reels are dominated by Aztec-themed regalia. Joining the lower value A to 10 playing card values are multi-coloured head dress and a dagger which award 2, 6 or 30 times your total bet if you land 3, 4 or 5 on a payline.

Next comes the pyramid which offers payouts of 3, 10 or 40 times your total stake. Best of all is the mighty Aztec warrior – land 3, 4 or 5 of these in combination and the cashier will be boosted by 4, 20 or 100 times your total bet. The golden bird pendant is the game’s wild – it doesn’t offer any payouts in its own right but it does replace all other symbols with the exception of the scatter.

That scatter is the gem-encrusted totem – it only lands on the middle 3 reels. If you manage to find it on reels 2, 3 and 4 on the same spin, you’ll trigger the Free Games feature – here you’ll be awarded 20 free spins. The Power Line is also in play on reel 1.

If there is no winner on show on reel 1, a multiplier will increase by 1. This starts at 2x and rises until you land a winning combination on that payline. When you do, the payout is boosted by the accumulated multiplier which is then reset to 2x.

You’re normally hoping to land a winner whenever possible but in this instance the longer you go without the better. A barren run followed by a win near the end of the free spins can prove lucrative. Theoretically, you could not have a winner until your last free spin which would give you a huge 21x multiplier!

There are some impressive rewards on offer in Aztec Power but expect plenty of lean spells along the way. The bright and bold design isn’t the best you’ll see but is pretty good for a Novomatic slot and the feature packs a decent punch. For some fast-paced, high variance, historic adventure, Aztec Power is a slot to consider. However, you cannot go wrong with NetEnt’s Gonzo’s Quest which has a similar theme and much more on the feature front.
