Read All About the Volatile Numbers and Stats

The hyper-volatile game is played on a 5×3 game window with 25 fixed pay lines. The main attraction on the 300 Shield Extreme slot is the free spins with progressive multipliers.

You can now join the Spartans on mobile or desktop from 0.25 to 12.50 credits. Lining up five matching symbols will pay 0.33x to 40x your bet.

The RTP of this high variance game is set at 95.299%, which is slightly below the industry average. Autoplay will allow you to set up 10, 25, 50, or 100 consecutive spins without interruption.

The Buy Pass Feature Explained

New on 300 Shields Extreme is the Buy Pass feature, where our reviewers discovered you can stake 60x your bet in one amount to gain direct access to the free spins round.

It’s an option if you’re pressed for time or it takes too long to trigger the feature organically. However, the free spin rounds are just as volatile as they are in the early game and thus can return often less than the staked amount. Our review team of the 300 Shields Extreme video slot urge to use the option with some caution.

Win Mega Bucks in the Free Spins Feature

As our review experts of the 300 Shields Extreme online slot know from their experiences on the original, this is a tough game to play. The base game won’t hold the balance for long and triggering the free spins round seems to take an eternity at times. But even getting into the bonus round will end often with a disappointing 5x to 10x bet win.

However, as high-volatility gamers know, that is the exact nature of such slot machines and there could at some point be a round which pays insane wins amounting to the worth of a brand new high-end car.

You will need to hit at least three shield scatters to receive the first 5 free-spins with a double multiplier, which is applied only to wins that contain a minimum of one wild symbol.

During those five spins, players need to collect two shields scatters to reach level two with a x5 wild multiplier and receive another five free spins. A display on the left of the game window indicates the progress. Any surplus scatters collected before the next level is triggered are carried over.

Getting 8 and 12 shields will advance the round to the third level of the slot game with a x25 multiplier, followed by progression to the fourth level with that insane x300 multiplier.

On the final level, every free spin can lead to wins of up 17,700x bet when five wild Spartan warriors line up on a pay line.

Try Other Games With Insane Multipliers

Having win multipliers in the bonus round can make the difference between a big win and a super mega win. Our review team of the 300 Shields Extreme slot also like Donuts from Big Time Gaming with a maximum x256 win multiplier and Primal Megaways from Blueprint Gaming with the multiplier peaking at a massive 7,776x.

A Verdict From an HV Fan

Admittedly, our review experts of the 300 Shields Extreme slot machine are fans of high-volatility games and were eagerly waiting to see how NextGen would modernize the epic slot and make it playable on mobile devices.

Well, here it is now, and it looks awesome. The best part is, that it has not been changed much and thus will provide exhilarating gaming sessions for years to come. Are you ready for a high-volatility rollercoaster?
