Theme and plot of the story

Theme and plot of the story“When our archers fire their arrows at you, there shall be so many that will block out the sun, “ said Xerxes to King Leonidis, the leader of the 300 Spartans at Thermopylae. “Then we shall fight in the shade, “ was the Spartan response.

Few historical battles are as well-known as the stand made by the 300 shields at the Hot Gates of Thermopylae, which took place in 480 BCE. The little band of warriors took on the whole army of the biggest empire on the face of the known earth, and they prevailed.

These valiant Spartans are now immortalized in 300 Shields Extreme, one of a vast collection of slot machines that have capitalized on the success of the film 300 to spin cash out of their heroic, yet ultimately sad, story.

Graphics, sounds, and animations are all included.

The visuals are rather good, as you would expect from a current Nextgen device. The audio is also quite good. A grain field near Sparta serves as the backdrop picture, while the reels are crammed with biremes, shields, and the classic Ancient Greek helmets that are so popular today.

The Bonus game transports the player to the battlefield, where he or she will encounter extra shield symbols and a fresh backdrop. These are used in conjunction with good animation to create an atmospheric change between peacetime and wartime situations. With each round of free spins, the backdrop changes to include more Persian forces, and arrows begin to appear on the reels as you go through the bonus round.

In addition to the visually appealing graphics, the soundtrack is equally captivating, serving to tie the whole slot together and emphasize the ancient Greek theme of the game.


Much of the gameplay is pretty simple, but the aesthetic aspects provide a sense of movement and elegance to the experience. The fundamental game is nothing more than a regular five-by-three-inch slot machine. It does include a gamble element, which enables players to choose the color or suit of the following card, which increases both the volatility of the game and the player’s heart rate.

Aside from that, there is the possibility to purchase a straight entry into the bonus game, which is the more fascinating gaming feature in any case (full details below).

Wilds, bonuses, and free spins are all included in this game.

The Wild symbol may be used to replace any other symbol with the exception of the Scatter symbol.

The Bonus game is triggered when three or more Scatter symbols appear. This feature begins with five free spins and a multiplier of x2 to get things started. During each free spin, every shield symbol that falls anywhere on the reels is collected and added to a tally on the right side of the screen.

After you’ve collected two shields, you’ll get five more free spins, with the multiplier increasing to x5. A total of five more spins are added when you get six shields, and the multiplier increases to x25. A total of twelve shields is required to attain the maximum multiplier of x300. Every time the multiplier increases, the backdrop changes, and extra blood and arrows emerge on the reels to complete the winning combination.

Bet sizes, return on investment (RTI), and variance

The return to player for this game is 95.30 percent, which is far lower than we would expect for a slot with this kind of theme. We use an average of around 96 percent as a standard, which this slot easily falls short of.

There was a wide variety of bets available on the site we tested, with a minimum wager per spin of $/£/€0.25 and a maximum stake per spin of $/£/€12.50.

The volatility of this game is high, making it a perfect match for our preferred strategies. Hopefully, they will have the same level of success as Leonidus.


Although the return to player on 300 Shields is low (only 95.30 percent), the game’s volatility is quite high, which helps to mitigate this disadvantage.

This game receives a cautious recommendation from us due to its excellent execution of the core gameplay, elegant presentation of the aesthetics, and entertaining extra feature (which we will discuss later).
