300 Shields

300 Shields is a NextGen Gaming slot which is based on the war between King Xerxes I of Persia and King Leonidas of Sparta in 480 BC. If the plot sounds a little familiar, it's probably because you've seen the 2007 film "300" which stars Gerard Butler as the brave Spartan ruler.

Although the 300 Shields slot is nowhere near as gory as the Hollywood blockbuster, its battle theme amply manages to convey the drama and desperation that such a momentous war causes for its participants. The game uses five reels and twenty-five paylines, and features a Free Spins Bonus where you can win multipliers of up to – you guessed it – 300 times your bet!

Appearance and Sound Effects

Behind the reels of 300 Shields, you can see the beautiful Grecian countryside before it was ravaged by the bloody Battle of Thermopylae in 480 BC. The summer sun blesses the cornfields, mountains, and hillside temples with its warming rays, but when you start spinning the reels, the mood suddenly changes as the sound of battle drums indicates that war is imminent.   

The paytable symbols include red-and-gold shields, daggers, flying arrows, wooden warships, archers, and the blood-spattered face of King Leonidas shouting commands to his troops. Plus, there are six low-value playing card symbols.

Bonuses and Special Features

The 300 Shields slots game features a wild symbol which is the image of King Leonidas. He can substitute for all symbols except scatters to help you conquer prizes by creating winning combinations. The scatter is the blood-smeared Shield, and you'll need three or more on the reels if you want to scoop some free spins courtesy of the Battle Feature.

The Battle Feature in 300 Shields offers you five free spins with all wild wins doubled, and you can retrigger the bonus with three or more Shield scatters to get five additional free spins.

The Battle Feature also comes with increasing wild multipliers as follows: get two or more Shields to gain a second set of five extra spins and a 5x wild multiplier; get six or more Shields to gain a third set of five extra spins and a 25x wild multiplier; get twelve or more Shields to gain a fourth set of five extra spins and a 300x wild multiplier.


300 Shields uses five reels, three rows of symbols, and twenty-five non-fixed paylines, and has an average RTP (Return to Player Rate) of 95.299%. The game lets you create winning combinations using matching symbols in succession from the leftmost reel to the rightmost reel.

Mobile Compatibility

The game is designed to work with desktops, laptops, mobile phones, and tablets, and includes mobile-friendly game controls when played on mobile devices.
