If you were a fan of NextGen’s 2014 blockbuster of an online slot game 300 Shields, you’re definitely going to need to take a few spins on the sequel title 300 Shields Extreme which hit UK slots casino websites in 2019.

As usual, the sequel hasn’t changed all that much from the original, but considering the dates of the releases, it’s satisfying to see that NextGen put plenty of effort into making sure that the graphic quality of 300 Shields Extreme reflected the release timeline. The other main perk to playing to the sequel is the brand-new bonus Battle feature which can shower you with multipliers which could go as high as 300 times your stake. That means that with 300 Shields Extreme you’ll get the chance to cash out with a massive max jackpot of 17,770x your stake amount.

300 Shields Extreme is playable from as little as 25p, or you can really make the most out of the 17,770x multiplier with a max bet of £12.50 and cash out with 222,125 coins. Although be warned, the volatility for 300 Shields Extreme is fairly high, so you’ll need to set your stake amount accordingly. The online slot game is definitely more suited to players who are chasing the bigger wins instead of the more frequent ones.

If you didn’t get to check out the original, 300 Shields was a Spartan-themed online slot game which did a good job of keeping bloodshed out of the gameplay. Instead, it did an incredible job of setting a serene scene of a nicely designed 5x3 reel slot grid over a background of an unruly wheat field with a Colosseum just in the distance. There’s nothing overly flashy about 300 Shields Extreme which makes it even easier to slip into a gameplay experience with an easy on the eye light design.

The 5x3 reel set contains 25 bet line, and 300 Shields Extreme will play out with 10 standard paying symbols along with the two bonus symbols which will pop up frequently to drastically improve the gameplay experience. The playing suit symbols A through to 9 are the low-value symbols which have the ability to offer 12x your stake when you find five of the A or K symbols in an adjacent winning line – that’s more than what some high paying symbols in other games offer! The higher valued symbols are even more generous, they include; the Spartan Fighter, a ship which is ready for battle, a sword, and an arrow. The highest paying of these symbols will offer you 20x your stake, yet the real money is won through matching the wild and the scatter symbol!

The blood-drenched Spartan Warrior is the wild symbol which will help you to create even more line wins by acting as a substitute symbol, as well as being able to replace every symbol aside from the scatter, you’ll also cash out on 40 times your stake amount when you create a winning line containing five of them. Then, there’s the shield scatter symbol, you’ll only need to put together two of them to see a cash award of 4x your stake, but five of them in a winning line will offer 100 times your stake. And if there’s three or more of them on the reels on the same spin, you’ll unlock the main bonus feature in 300 Shields Extreme.

Game Bonus Features

There is only one bonus feature in 300 Shields Extreme, but NextGen has made sure that the online slot game certainly isn’t lacking in generous rewards in return for your stake amount.

Whether you are ready for battle or not, the Battle Bonus Feature will be triggered when you find 3 or more scatters on the reels. While it’s slightly similar to a free spins feature, NextGen has made sure that you’ve never played a free spins round like this one.

When the Battle Feature is triggered you will be offered 5 free spins, during which each line win will be doubled by the 2x multiplier. That may be a relatively low number of free spins to start off with, but your objective in the side game is to collect more scatter shields to top up your free spins tally and watch the multiplier reach on higher numbers.

2+ shields will give you 5 more free spins and a 5x multiplier
6+ shields will give you 5 more free spins and a 25x multiplier
12+ shields will give you 5 more free spins and a 300x multiplier

The main mode of play is incredibly generous in 300 Shields Extreme, yet, that’s nothing compared to what is up for grabs in the free spins bonus feature. NextGen must have known how alluring their take on a free spins round was as they fitted 300 Shields Extreme with a function which allows you to buy your way into the free spins. This will come at a price of 60x your current stake, which is risky, but it has the potential to pay off. You’ll also need to bear in mind that collecting 12 or more shields is fairly difficult to get that 300x multiplier.
