300 Shields Extreme Game Highlights

The 300 Shields Extreme slot may seem very similar to its predecessor at first glance, but NextGen has certainly upped the ante with some notable additions to the game features in this new version. Not only is the scatter symbol worth more, but you also have the chance to double or quadruple your winnings with a Gamble feature. Plus, you can jump directly into the Battle feature (free spins round) with the Bonus Buy option. 

Drawing inspiration from the movie “300,” both games are filled with gladiator-themed elements to draw you right into the world of central Greece during the Greco-Persian Wars. This slot is enhanced by a range of elements, from roaring gladiators, swords, and symbols pierced by arrows to the game’s theatrical soundtracks and next-level animations. 

Bets range from as little as $0.25 to a maximum bet of $12.50, so this slot is perfect for more conservative, budget-conscious players. Even with the lower betting limits, high rollers can still get their fill of excitement with the game’s Buy Pass, which enables you to pay to enter the free spins round and costs $750 if you have the maximum bet activated.

Does 300 Shields Extreme Pay Real Money?

BetMGM Casino gives players in legal U.S. casino states the opportunity to play different types of online slots for real money, including video slots like 300 Shields Extreme. To play slots online and withdraw real cash winnings, you must be physically playing from Pennsylvania, New Jersey, Michigan, or West Virginia – the states where BetMGM Casino is legally active. 

How To Play 300 Shields Extreme

The 300 Shields Extreme slot is played on a simple 5×3 grid with 25 fixed paylines. The game controls are displayed on the right-hand side of the reels, while your bankroll balance and total bet size are displayed across the bottom of the game screen. 

To play, choose your bet size using the “+” or “‒” buttons or the game menu. Press “Play” to start a round, then wait for the reels to stop spinning. A win will be triggered if a certain number of matching symbols appear on a payline. For most symbols, you need at least three of a kind to form a winning combination. However, there are a few high-paying symbols and special symbols that trigger a win for only two of a kind on a payline. 

If you land winning combinations on more than one payline, the payouts for each combination will be added together to make the total win amount. Any scatter wins will also be added to your payline wins. 

Below are some additional features that NextGen has included to improve gameplay:

  • You can set the reels to spin automatically for 10, 25, 50, or 100 spins with the autospin (the spins can be stopped at any time).
  • The space bar or enter key can be used to spin and stop the reels.
  • Customization options in the game menu can be used to control the quality of the game effects, the soundtracks, bet sizes, and the position of the “Play” button.

300 Shields Extreme Game Features

In addition to smooth, easily customizable gameplay, this slot game includes a few more exciting features to engage you. 

Wild and Scatter Symbols in 300 Shields Extreme

In addition to the high and low-paying base game symbols in 300 Shields Extreme, this game also includes two special symbols with unique functions: 

  • The scatter symbol (the shield): Land three or more of these symbols to trigger the free games round. This symbol also has huge payouts for larger winning combinations (up to 2,500x).
  • The wild symbol (the warrior): This symbol substitutes for all other symbols in the base game except the scatter. 

The Buy Pass Feature in 300 Shields Extreme

This online slot allows you to bypass regular gameplay and trigger this slot’s bonus round (known as the Battle feature) by paying for it. Consider your bankroll carefully before you activate the feature because buying into the bonus round will cost you 60x your total bet ($15 with the minimum bet activated and $750 with the maximum bet activated).

The Gamble Feature in 300 Shields Extreme

After any win, you can click on the playing card symbols to the right of the reels to activate the Gamble feature. This takes you to a game screen with a face-down playing card in the center and gamble choices on either side. Here, you can either accept your win amount or choose to gamble your winnings to potentially multiply them. Keep in mind that if you lose the gamble, you will forfeit your spin winnings.

To gamble, you will need to choose a color (red or black) or a playing card suit. Once you have made your choice, the playing card will flip over. If it matches your choice, your win will be either doubled (for a correct color choice) or quadrupled (for a correct suit choice). 

300 Shields Extreme Bonuses and Jackpots

The main attraction in 300 Shields Extreme is the Free Games bonus. Triggered by three or more shield scatters, this feature offers progressive multipliers and some impressive reward potential. 

When you first trigger the bonus, you’re awarded five free spins with a 2x multiplier on any wins, including a wild (warrior) symbol. If two or more scatter symbols land anywhere on the reels while this feature is active, you will be awarded additional spins, and the multiplier value for the round will increase. 

Every scatter symbol that lands on the reels. At the same time, the Free Spins feature is active and will increase your shield count (which is displayed to the left of the reels in this round), awarding you additional free spins, increasing the multiplier for warrior symbol wins, and bringing you one step closer to the maximum prize in this game. 

  • Two shield symbols: Five more spins and a 5x multiplier for warrior symbols. 
  • Six shield symbols: Five more spins with a 25x multiplier. 
  • Twelve shield symbols: Another five spins are awarded, with all warrior wins multiplied by 300x.

While there’s no progressive jackpot, the game boasts a maximum win potential of 17,773x your total bet. This can be achieved during the final free spins stage, particularly when five warrior symbols align on a payline with the 300x multiplier active.

How To Win 300 Shields Extreme

This game includes 12 different symbols. These symbols include playing card royals with arrows shot into them, an archer, a sword balancing on its sheath, and arrows flying through the air, all of which require three of a kind on a payline to form a winning combination. 

Other symbols include a ship, a shield, and a warrior. These symbols pay out for matching combinations of two or more symbols on a payline. 

As all wins are multiplied by coin value, larger bets will result in larger payouts should you land a winning combination. However, because this is a high-volatility slot game, wins will be less frequent, so avoiding playing on the max bet for every spin is a good idea. Adjust your bet sizes as you play to conserve your bankroll and extend your gameplay. 

300 Shields Extreme Graphics and Design

The design of 300 Shields Extreme shares many similarities with the original version of this slot game, including the battle-themed slot symbols on a simple slot grid with muted colors. The gameplay is set against a backdrop of a serene ancient Greek landscape, with crops swaying in the wind and glimpses of ancient architecture in the distance. 

The crisp graphics are complemented by subtle yet eye-catching animations, while a tranquil soundtrack adds to the calm atmosphere of the base game. When the free spins round is activated, the intensity dramatically increases. The soundtrack shifts to a theatrical score that heightens the sense of epic warfare. The backdrop also changes into a mountainous ocean scene, creating a stark contrast to the peaceful base game setting. Blood covers the reels with each spin, vividly bringing the battle theme to life. 

300 Shields Extreme Symbols

Instead of BARS, bells, cherries, and other iconic slot symbols, this game includes 12 different symbols based on its Spartan theme. Winning combinations of these symbols will be multiplied by the coin value. Symbol combinations pay out as follows: 

Symbols 2 of a Kind 3 of a Kind 4 of a Kind 5 of a Kind
9 and 10 N/A 4x 10x 100x
Q and J N/A 5x 12x 125x
A and K N/A 10x 15x 150x
Sword and flying arrows N/A 12x 20x 200x
Ship and archer 2x 15x 100x 250x
Shield (scatter) 50x 125x + free games 300x + free games 2,500x + free games
Warrior (wild) 5x 25x 250x 1,000x
