What Is 300 Shields Mighty Ways?

300 Shields Mighty Ways is a video slot with a Spartan warrior theme, released by Light & Wonder in Q4 of 2022.

Formerly known as Scientific Games, the studio is bringing us a second entry featuring the Mighty Ways slots mechanic, after the murder & mystery-themed Cluedo Mighty Ways.

In addition, 300 Shields Mighty Ways can be considered a loose continuation of 300 Shields, a classic payline slot released by NextGen Gaming back in 2014.

In fact, it’s not the first time Scientific Games tried to revamp NextGen’s creation – their first attempt was 300 Shields Extreme, which more or less stayed true to the general outlines and bonus features. The only novelty element then was the introduction of a buy pass.

This time around, 300 Shields Mighty Ways promises to significantly change the reel layout and the extras. Actually, the only similarities are the focus on Spartan mythology, weapons, artefacts, and landscapes.

However, in terms of bonus features, 300 Shields Mighty Ways truly upped the stakes with the introduction of win reactions, free games with progressive multipliers, and not one, but TWO buy passes!

So, what are you waiting for? Dust that metal helmet from your closet and let’s get hunting for those prizes – our 300 Shields Mighty Ways slot review is ready to awaken the warrior in you!

300 Shields Mighty Ways Top Features

Light & Wonder has drawn mountains of inspiration from the original 300 Shields slot. For this Mighty Ways sequel, the studio kept the legendary free games feature with doubled wild wins. What’s more, fans can once again trigger a juicy maximum multiplier of 300x during the free games.

The win reactions in the base game impress as always, with symbol destructions and consecutive payouts. The icing on the cake is that we can trigger two different buy passes, if we don’t feel like waiting too much.

In this game, the stakes are higher and the battlefield is roaring with tension, so join us as we break down each feature!

Cascading Reels & Mighty Ways

If you follow our Megaways™ slots list religiously, then you’ll certainly be familiar with the cascading reels mechanic. However, this time around, we’re seeing it paired up with Light & Wonder’s original Mighty Ways engine, which leads to a different, more rewarding outcome.

As opposed to Megaways™ slots, which feature between 64-117,649 ways to win, in 300 Shields Mighty Ways, the starting number of ways to win is 729 and the maximum is 262,144.

The cascading reels feature will come to play after one or more winning combinations. The symbols involved explode and get removed from the reels, as new ones fall from above in their place. The mechanism continues as long as new winning combinations hit, so you can  get consecutive payouts on the same spin.

So far so good, but here is where things get interesting: for each symbol that is part of a win, the reel it falls on increases in height by one. Each reel can hold a maximum of eight symbols, at which point you’ll activate 262,144 ways to win (8x8x8x8x8x8).

Do keep in mind that the reels will be reverted to the three symbols height between the base game and the free spins.

Free Games

The game’s scatter or bonus symbol is the shield. To trigger the Free Games feature, you’ll need at least three shield symbols in any position on the reels, and you’ll be rewarded as such:

  • Three shields – five free games
  • Four shields – seven free games
  • Five shields – 10 free games

As an added bonus, the Mighty Ways engine stays active during the Free Games, as well: that means that each win will award a cascade. As the reels increase in size, so does the number of ways to win.

During this round, each win involving the warrior wild symbol will come with a 2x multiplier for double the fun!

To top things off, all shield scatter symbols will be collected on the left side of the reels, on the Shield Trail: the more shields you have, the higher the number of free spins you can acquire and the higher the value of the multiplier. Here’s how it works in practice:

  • Two scatter shields add five free spins with a 5x win multiplier
  • Six scatter shields add five free spins with a 25x win multiplier
  • 12 scatter shields add five free spins with a 300x win multiplier

After you’ve reached that sweet spot and collected 12 scatter shields, landing three additional shields on the reels will award you an extra five free spins with a 300x win multiplier.

Super Free Games

If you’re the bravest warrior of the land and match six scatter symbols during the base game instead of three, you’ll trigger the Super Free Games feature… which you’ll need to think of as a free spins bonus with even more goodies!

To start off, you’ll receive five free spins – the major difference this time is that each win involving the warrior wild symbol will receive a 300x multiplier by default.

Moreover, during this round, collecting two, six, or 12 additional shields will award you five more free spins.

Lastly, every time three or more shield symbols fall on the grid simultaneously, you’ll receive five extra spins.

The 300x warrior multiplier stays active from start to finish.

Buy Pass

For non-UK players, 300 Shields Mighty Ways will come with two buy passes or bonus buy features, which can be found listed on the bottom left side of the slot window.

Each of them grants direct access to the bonus round, for a fixed cost:

  • Pay 50x your bet to trigger the Free Games feature (potential to win five, seven, or 10 free games).
  • Pay 1,566x your stake to trigger the Super Free Games feature.

300 Shields Mighty Ways RTP, Volatility and Win Potential

300 Shields Mighty Ways slot has an estimated base game RTP (Return-To-Player) score of 95.99%, which is slightly below the Megaways™ slots we typically analyse. The good news is that activating the buy passes increases the RTP score by up to 96.06%.

The game has a high volatility/variance level, giving you larger wins with a low frequency.

The top payout is quite decent for a video slot, capped at 30,000x your stake, which is almost double the 17,773x max win found in the original game. In real-money terms, the max win in the Mighty Ways version can be of between £/€/$6,000 and £/€/$600,000.

300 Shields Mighty Ways Stakes and Betting Range

You can become a member of the elite Greek military forces from ancient times for just £/€/$0.20 per spin, making this a worthy contender for our low-stakes Megaways™ slots list.

The maximum bet, meanwhile, is set at £/€/$20.

This range should be enough to keep most players happy, though high rollers may have different, higher expectations.

Theme, Slot Design & User Experience

While NextGen’s original 300 Shields was set in a tall wheat field during summer, overseeing the Greek skylines and city architectures, the subtle changes brought by Light & Wonder add a touch of unmistaken dramatism.

The previously green fields now look drier and there are more roads present. These have been paved by the warriors as they advanced towards their goals. The slot’s wild symbol is eerily similar in design to the actual illustrations of the legendary king Leonidas, who led the 300 Spartan warriors to battle. As such, it’s obvious that Light & Wonder is also paying tribute to the 2006 historical action movie, 300.

In this game, it appears that we’re witnessing an episode from the Peloponnesian War in slot form, with polished visuals and increased attention to detail.

The Spartan helmets, bloody daggers, arrows and spears are further completed by an orchestral action music, which fills us with adrenaline, battle spirit and dread, all at once.

Paytable and Special Symbols

The HD graphics and realistic symbols represent a far cry from the outdated visuals of the original – with that said, the key elements of the Spartan theme are kept, such as masked fighters or weapons.

  • The low-value symbols are represented by the card suit ones, ranging from 9 to A. These pay between 0.50x- and 0.90x-your-stake for six-of-a-kind.
  • The high-value symbols are more thematic and include, in order of payout, the arrows, sword, ship, Spartan helmet, and archer. These pay between 1.5x- and 10x-your-stake for six-of-a-kind.

The game also comes with two special symbols.

  • The Warrior Wild Symbol – As always, this replaces all regular icons except for the shield scatter, but it also doubles wins during Free Games. This symbol never lands on Reel 1.
  • The Shield Scatter – Three of these will trigger the Free Spins while six will trigger Super Free Games.

300 Shields Mighty Ways Mobile Play

Due to the reel layout and staggering attention to detail, 300 Shields Mighty Ways is best played on a device with a larger screen. However, if you wish to play on the go, this game is also compatible with smartphones and tablets that run on Android/iOS systems, thanks to the HTML5 technology.

You can use either landscape or portrait mode and play straight from your browser.

How to Play 300 Shields Mighty Ways Slot

Before you start playing, it’s imperative to understand the slot layout – because of the Mighty Ways system, you’ll play with a dynamic reel configuration. The default is six reels, three rows, and 729 ways to win, and it can increase to eight rows and 262,144 ways to win.

To trigger a winning combination, you need at least three identical symbols on adjacent reels, from left to right only.

Once you open the slot window, here are the key areas to look over to get started with your gameplay:

  • Coin menu – located on the right side of the screen, here is where you can set your stakes using the ‘+’ and ‘-‘ buttons.
  • Settings – located on the left side of the screen, here you’ll find details about the symbol values, the Mighty Ways engine, and the bonus games.

Aside from spinning manually via the Spin button or the Space Bar, the game comes with two additional modes: Autoplay, where you can set between five and 100 automatic spins, and Quick Spin/Turbo Mode, through which the game will spin faster.

Remember that UK players don’t have access to some of these modes due to UKGC legislation.

To better manage your budget, you can also set Single Loss Limits of £/€/$50 and £/€/$1,000 and Single Win Limits of £/€/$50 and £/€/$200.

Finally, if you’re from an approved jurisdiction, you can activate the bonus buy features straight from the slot window.
