300 Shields Extreme is powered by NextGen Gaming and is the sequel to the cult favourite 300 Shields. With 5 reels and 25 paylines, you can spin away from 25p to £62.50 per spin across all devices. With a Spartan theme, it’s all about the Battle feature where wins involving the Warrior wild can lead to multipliers up to 300x!

Visually, 300 Shields Extreme is almost identical to the original, 300 Shields – it does have improved graphics and animations though. Set on a rural hillside with temples in the backdrop, it has a calm feel to it. Symbols on the reels Spartan style A, K, Q, J, 10 and 9 royals as well as arrows, swords, ships and fighters. The Warrior is the wild symbol and substitutes for all symbols bar the scatter – 5 on a payline will reward you 40 times your total stake.

The most important symbol is the shield scatter – 2, 3, 4 or 5 on a payline will give you 2, 5, 12 or 100 times your stake. 3 or more though will trigger the Battle feature where you’ll begin with 5 free spins – now, any winning combination involving the Warrior wild will apply a 2x multiplier to your winnings.

They key in the Battle feature is to collect shield scatters as these will reward you with more free spins as well as increased Warrior wild multipliers up to 300x:

• Collect 2 or more shields to get 2nd set of 5 free spins with Warrior wild wins subject to a 5x multiplier
• Collect 6 or more shields to get 3rd set of 5 free spins with all Warrior wild wins subject to a 25x multiplier
• Collect 12 or more shields to get 4th set of 5 free spins with all Warrior wild wins subject to a 300x multiplier

If you land 3 shields on a free spin, you will get another 5 free spins in the stage you’re in – if you were to do this in the final stage, you could get 10 free spins with the 300x multiplier. If you want to buy your way into the Battle feature, you can click on the Buy button to the left-hand side of the reel set – this is known as the Buy Pass feature and will cost you 60 times your total stake.

Now, getting to the final stage will be extremely difficult as 300 Shields is as high variance a slot as they come. Saying that, there’s a huge 17,770 times your total stake to be won from every free spin involving the 300x wild multiplier. This is the same as the original though.

The only differences from the original are slightly better graphics/animations and the Buy Pass feature where you can buy your way into the Battle feature for 60 times your stake. Everything else is exactly the same – whilst 300 Shields and 300 Shields Extreme are recommended, we would like to have seen another bonus feature added for example. Saying that, it’s highly volatile and worth playing if you’re chasing the big win!
