300 Shields Slot Review

300 Shields is a video slot game with 5 reels and 25 paylines – it’s brought to you by NextGen Gaming. You can play for as little as 25p a spin to a whopping £200 a spin. It features a 1,000 coin jackpot which you can trigger by getting 5 Wild symbols. 300 Shields is has a Spartan theme as it’s loosely based on the ‘300’ blockbuster movie. This slot game has increased in popularity due to its 300x multiplier.

The main feature is the Battle Feature Free Games bonus round. This can trigger this feature by getting 3 or more Shield symbols anywhere across the 5 reels. You will be awarded with 5 free spins with all Warrior wins doubled (2x multiplier). During the free spins, you will see Shields – this will increase your shield count and can increase your Warrior win multiplier up to 300x. Here are the details:

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

What is even better is that you can re-trigger the feature whenever you get 3 or more Shields. For each 3 Shields you get, you will get an additional 5 free spins (or games as they are referred to). The possibility of a 300x multiplier is not common at all in online slot games so 300 Shields is unique in that respect.

I’ve played this game countless times and haven’t got the 300x multiplier yet but the wins on the 25x multiplier have been kind to us. As mentioned before, this is a high variance slot game which means that wins will be few and far between but when they come, it will feel like all your Christmases have come at once. We recommend you play at low stakes initially so you don’t lose your entire bankroll quickly.

If you like high variance slots, I highly recommend Black Knight II by WMS which can give you 3 sticky wild reels in the feature – it won’t happen often at all but well worth the wait if it does. Another volatile slot I recommend is Microgaming’s Immortal Romance which is an absolute must.
