About This Slot

Alongside games like Dead or Alive, Book of Dead and Raging Rhino, the first 300 Shields game, released in 2014, is one of the original hard hitting high variance slots. The industry has come a long way since then but the appeal of this kind of high-risk gaming where long spells of frustration are punctuated by pulsating win sequences and huge pay offs will never go away. In fact, if anything high volatility slots are more popular today than ever, driven on by the creativity and innovation of studios like Big Time Gaming, No Limit City and Relax Gaming.

So, it’s no surprise that Light and Wonder (formerly SG Digital) are looking to extend their 300 Shields franchise with a new release that retains the games high risk maths whilst updating the gameplay with a more modern feel. Specifically, the team have added an on-trend expanding reels mechanic called Mighty Ways that gives you up to 262,144 paylines per spin.

 The action still takes place against the backdrop of the setting for the epic battle between Spartans and Persians, with rolling wheat fields and stone buildings under a pale blue sky. Aside from the Mighty Ways, features familiar to fans of the original game are in play – Warrior Wilds with potentially high value multipliers (up to 300x) and lots of Free Games with the chance to earn more by collecting extra scatters.

300 Shields Mighty Ways is released at UK slot sites on September 20th 2022.

RTP, Variance and Top Payout

As every high variance fan knows, 300 Shields is one of the original bad boys of the genre. And this update is no different. Prepare for seriously high-risk gaming. Here are the maths:

  • 300 Shields Mighty Ways is a high variance slot. It will rarely pay out the big mone, but when it does it can unleash some huge win sequences. Big multipliers of up to 300x will help trigger these events.
  • The top win here is advertised as 30,000x.
  • The RTP of 300 Shields Mighty Ways is 95.99%.
  • Bets start at 20p per spin.

Symbols and Graphics

The paytable symbols will be familiar to anyone who has played either of the two previous incarnations of 300 Shields. Here are the highlights:

  • 300 Shields is a 6 reel by 3 rows slot with potential to expand to 8 rows high on every reel. The maximum number of lines in play is 262,144 (8x8x8x8x8x8).
  • Wins are created by landing 3 or more identical symbols on adjacent reels from left to right.
  • Low payers are the cards 9 through to Ace. They will earn you a win of 0.5x to 0.9x for six on a payline.
  • The five premiums are represented by the instruments of war – the arrow, the the sword, the warrior helmet, the archer and the ship. The archer pays out up to 10x for six on a payline.
  • Look out for the Warrior Wild, responsible for all the best wins in this game. He lands on reels 2 to 5 and subs in for all other symbols to form wins. Crucially, he also comes with multipliers in the free spins round.
  • Shield Scatters are required to unlock the bonus round – they can land anywhere on the grid at any time.

Gameplay and Features


  • Central to the entire game is the Mighty Ways mechanic, Light and Wonder’s own take on the expanding reels trend first seen in Big Time Gaming’s Megaways™. In this instance it’s a mix of expanding reels and avalanche wins.
  • After any winning spin, the winning symbols are all removed from the reels. Reels involved in this process then expand by two rows, up to a maximum of 8 rows high.
  • If all 6 reels reach 8 rows high then there are 262,144 paylines activ


As ever, Shield Scatters are key to winning big in this game.

  • 3, 4 or 5 Shield Scatters gets you 5, 7 or 10 free games.
  • 6 Shield Scatters triggers the Super Free Games round.
  • During Free Games, ALL wins including Warrior Wilds are doubled (2x multipliers).
  • During Free Games Shield Scatters are collected. They can unlock further Free Games and extra Multipliers. Like this:

Collect 2 Shield Scatters for 5 more Free Games with a 5x multiplier on wins with a Warrior Wilds symbol

Collect 6 Shield Scatters for 5 more Free Games with a 25x multiplier on wins with a Warrior Wilds symbol

Collect 12 Shield Scatters for 5 more Free Games with a 300x multiplier on wins with a Warrior Wilds symbol

In Super Free Games, collecting 2, 6 or 12 Shield Scatters earns you 5 more Free Games each time, but in this case, EVERY win with a warrior symbol gets a 300x applied to it!   

And finally… landing 3 or more Shield Scatters simultaneously on the grid gets you 5 extra spins.

Our Verdict

300 Shields Mighty Ways is a worthy update on the original slot and its sequel, 300 Shields Extreme. By keeping the core elements of the original game whilst also updating the gameplay with modern features, Light and Wonder have created something for both veterans of slots play and the new generation of gamblers.

In Mighty Ways the developers have found a way to set up an expanding reels mechanic in a new way, with Avalanche Reels being the trigger. This way of enhancing the paytable keeps things interesting in the base game before the main event.

Meanwhile, the Free Games themselves are easy to follow compared to some of the more complex high-risk slots on release right now like those from No Limit City for example. Your goal here is simply to land as many Shield Scatters and Warrior Wilds as you can. Keep going and you’ll get more free spins and more high value multipliers.

And if you are really lucky you’ll hit the promised land of those 300x Warrior Wilds!

Finally, a word on the top payout. With NLC releasing games that showcase a 300,000x top win, 300 Shields Mighty Ways 30,000x top jackpot isn’t as radical as it would have been 8 years ago. Nevertheless, the simple but intense gameplay of the bonus round means that in our opinion, 300 Shields is back and more than holding its own against the new wave of games in 2022.
