300 Shields Extreme Review

300 Shields Extreme is an upgraded version of the popular predecessor, and it was launched by NextGen Gaming 11 March 2019. The game has 5 reels, 3 rows and 25 ways to win, and in this upgraded version you can now buy the all-important free spins feature. Not much action in the base game, but the free spins feature has 3 levels with a 300x multiplier on the last level, and you can win up to 17,770x your stake on any given spin.

300 Shields Extreme RTP, variance & technical data

Before we take a closer look at 300 Shields Extreme slot, we thought you might like to know the game’s most relevant technical data:

  • RTP: 95.299%
  • Volatility/Variance: High
  • Layout: 5x3
  • Paylines: 25
  • Bonus features: Free spins and Buy-in feature
  • Bets: 0.25 to 12.5
  • Max wins (coins): 222 125

300 Shields Extreme has an RTP of 95.299%, which is a bit below the industry average of 96%. Return to Player tells you how much a given game will pay out in the long run, and the opposite number will be the House edge (in this case 4.701%). Also note that this is a highly volatile game, and you can expect to wait a while between significant wins. Adjust your bet level according to your bankroll, and you should be fine.

This game is not an official branded title, but it’s still loosely based on the blockbuster movie “300” from 2007. This is actually a relaunch from NextGen Gaming, and they have brushed up on the graphics, gameplay and added the possibility to buy the all-important free spins feature. Not much happens in the base game, so this is really all about the free spins feature where you can win massive payouts because of the 300x multiplier.

The game is inspired by the persian wars, and the Shield scatter symbol is the most important symbol in this game. Not only does it trigger the free spins feature, but you can also win some decent payouts if you land 5 on a payline. The graphics are much better than the original game, but nothing much has changed when it comes to the game mechanics and the mathematics behind the slot.

300 Shields Extreme bonus features

300 Shields Extreme slot is extremely volatile, and you either win big or you win nothing here. The base game does not offer much excitement at all, and you’ll find no bonus features or win potential to speak of here. It all happens in the free spins feature we’ll discuss below, and since this feature is so important you can even purchase it for 60 times your stake, if your wish.

300 Shields Extreme free spins

The scatter symbol on 300 Shields Extreme slot is, you guessed it, the Shield. 2, 3, 4 or 5 scatters on a payline will give you a win of 2x, 5x, 12x or 100x your stake. Land at least 3 Shield scatters and you’ll trigger the all-important Battle Feature where you’ll start with 5 free spins. Any winning combo that involves the Warrior wild symbol will boost your winnings by 2x.

In the Battle feature you need to collect as many new Shield scatters as possible, as this will give you evermore free spins. You can also increase the Warrior wild multiplier up to a whopping 300x:

  • Collect at least 2 Shields and get 5 new free spins with 5x Warrior wilds
  • Collect at least 6 Shields and get 5 new free spins with 25x Warrior wilds
  • Collect at least 12 Shields and get 5 new free spins with 300x Warrior wilds

You can also land 3 Shield scatter on a free spin, and get yet another set of 5 free spins on whatever level you’re at. If you do this on the final level you’ll receive 10 free spins with 300x Warrior wild multiplier.

300 Shields Extreme jackpot (max win)

While there is no progressive jackpot in the traditional sense on this game, you can certainly win some impressive payouts here. If you reach the final level in the free spins feature you can win up to 17,770 times your stake on every free spin with the 300x multiplier. This amounts to £222,125 if you play with maximum stakes.

300 Shields Extreme mobile & tablet

Sure, you can play 300 Shields Extreme on both mobile and tablet, and this game is great fun on any handheld device. Bring it with you wherever you go if you want to go for the big wins, and you can play on your Android device, as well as iPhone and iPad.

SlotCatalog verdict

The original 300 Shields slot gained some popularity, so it’s understandable that NextGen Gaming did an “extreme makeover” and relaunched the new and brushed up version. Granted, the only real difference from the original game is the free spins buy-in option and the crips HD graphics. That being said, we certainly prefer to play this version for the given reasons, and since the original game was so good, why change a “winning team” too much.


  • Win up to 17,770x your stake
  • Free spins feature with 3 levels and 300x multiplier
  • Upgraded HD graphics and buy-in feature


  • Max win is limited by a rather low maximum stake
  • Hard to get to free spins level 3 with 300x multiplier
