300 Shields Extreme Symbols and Payouts

With our 300 Shields Extreme review, our team enjoyed the time playing on the five-reel, 25 payline game. The winning combinations run from left to right, unless you land a scatter, which pays any direction.


While playing the slot, we enjoyed the art of the various symbols. They’ve been done well, and evoke the target theme of the slot.

Of all the symbols, the scatter shield pays the highest and in any direction. It’s closely followed by the wild warrior, who multiplies by up to 1000 times the stake.

Next is the battleship and the archer, who hold equal value, and then the sword and arrows.

The royals, from nine through ace, are the lowest paying of the symbols.



There are 25 ways to win according to the paytable.

The wild symbol is incredibly handy in adding to the winning combos because it replaces everything, except the scatter shield. It also multiplies winnings significantly.


300 Shields Extreme Min / Max Bets

In our 300 Shields Extreme review, we find the slot suitable for players of all types. The minimum bet is $0.25, and the maximum goes up to $12.50.

It’s a little low but ensures your bankroll goes further. The 17,773x multiplier on the maximum stake could return thousands.

300 Shields Extreme RTP, Volatility & Hit Frequency

Our 300 Shields Extreme review found the RTP somewhat disappointing, sitting below the industry standard of 96%. The 300 Shields Extreme RTP is 95.299%, the same as in the original version.

However, if you opt to go for the buy-in bonus pass, the 300 Shields Extreme RTP goes up ever so slightly to 95.658%.

300 Shields Extreme Jackpot And/or Maximum Win

While playing the slot, the team found that you can win a maximum of 17,773x. If you make it through to the third level of the bonus game, every win has a multiplier of 300x, making it the most lucrative part of the slot.

300 Shields Extreme Features

Several features of the game stood out for this 300 Shields Extreme review. The base game wasn’t spectacular, but the bonus game ups the ante. One part of the main game that I enjoyed most was the gamble feature.

Wilds and Gamble Feature

The wild warrior is one of the most lucrative symbols in the game and lands on any of the reels. When he’s included in a winning combination, you can boost your winnings by activating the gamble feature.


You can easily identify the wild warrior symbol by his silver blood-splattered frame and his golden helmet. He replaces all other symbols except for the scatter shield. He carries a significant multiplier if he’s on a winning payline, with the maximum at 1000x.

Gamble Feature

When you land a win in the base game, the gamble feature will appear.

You can use it to multiply your winnings by correctly guessing the color or the suit of a card that’ll be generated.

300 Shields Extreme Free Spins

There’s no specific symbol for free spins; however, when you land three or more of the base game’s scatter shield, you unlock the bonus battle round and receive five free spins.

You’ll receive extra free spins when you land more shields in the bonus game.

Bonus Game

You have two options to unlock the bonus game: you can purchase a buy-in pass at 60x stake value, or you can wait to land three shield scatter symbols on a spin.

Once the battle bonus game is triggered, the real fun starts, as we found with our 300 Shields Extreme review.

When you’re in the battle bonus game, you’ll start with your five free spins. But, the more shields you collect, the higher the wild warrior multiplier becomes and the more free spins you accumulate.

After two additional shields, you collect five free spins, and a five times multiplier on warrior wins. A further six collected adds another five spins and increases the multiplier to 25.

You need another 12 shields to receive five more free spins in the final level, and the multiplier goes up to 300x.

Graphics & Sound

NexGen Gaming took the original game and gave it a full makeover, and it did a superb job of it. The swaying field below the Parthenon in the golden sun is beautiful in the base game.

The way they built up the intensity with blood splatter (not on the gore side) and the feel of a war battle in the bonus game is spectacular too.

The selected music adds to the uniqueness of the ancient Greek era.

Other Slots to Play If You Like 300 Shields Extreme Slot

The original 300 Shields is a classic if you can find it. Rich Wilde and the Shield of Athena are also excellent alternatives.

300 Shields Extreme Review - Conclusion

We can conclude in our 300 Shields Extreme review that the game is 100% worth the hype. The music builds up the anticipation of landing another shield and captures your attention straight away.

The bonus game that unlocks is the best aspect of the slot and is the feature that holds the most excitement.

However, the base game falls flat compared to the battle bonus game and could do with a little more magic.

The only other critique we have is the low 300 Shields Extreme RTP. They could have improved this in the slot’s makeover.
