300 Shields


The 300 Shields online slot is loosely based on the Hollywood blockbuster, 300, starring Gerard Butler as King Leonidas. In this NextGen Gaming slot, the story of the violent battle between King Leonidas’ Spartans and the army of King Xerxes I of Persia at the Battle of Thermopylae in northern Greece in 480 BC is made more palatable through the use of an idyllic countryside background. But, the war theme runs strong in the paytable symbols where you’ll see arrows, warships, bloody swords, fierce soldiers, and shields.

This slot is an action-packed game which uses a wild symbol that can pay out as much as one thousand times your bet for a five-of-a-kind wild combo. Plus, it can help you conquer other prizes by substituting for the game’s remaining symbols. Raise your sword and prepare to reap the rich rewards of battle in the Free Games Feature, where you’ll gain twice as much loot for wild wins, and further sets of free spins by collecting extra scatter symbols. And, if you manage to gain the maximum number of scatters, your final five free games will have any wild wins multiplied by a mammoth x300!

Why we love it

For starters, this online slot encourages you to find out more about the Spartans if you managed to bypass the film, 300. As it’s based on actual historical events, the slot seems far more engaging than one which uses a fantasy theme. Seeing the faces of the brave warriors charging into battle as they appear on the reels combined with the cinematic soundtrack makes for an adrenalin-charged playing experience. But, even without the powerful theme, this online slot still manages to exceed our expectations by awarding doubled wild wins in the Battle Feature Free Games Bonus, plus the opportunity to earn wild multipliers worth as much as 300x when new scatter symbols land on the reels.

The betting range is also particularly palatable, as you can choose how many paylines you wish to play with, meaning that the lowest bet-per-spin is just 2p! And, for the high-rollers, there’s a more than ample maximum bet of £250 per spin. As for how much money is on offer to anyone who conquers 300 Shield’s top jackpot, it’s a very pleasant sum of one thousand times your stake.

The Spartan warrior wearing a blood-spattered helmet is the game’s wild symbol, and it can dish up superb prizes of up to one thousand times your bet. It also has the ability to contribute towards winning combinations by substituting for all symbols except scatters.


The red-and-gold shield represents the scatter symbol in 300 Shields, and it awards scatter wins of between two and one hundred times your bet when it appears two or more times anywhere on the reel set.


Three or more of the shield scatter symbols allow you to enjoy maximum action via the Battle Feature Free Games bonus. You begin with five free spins, and every prize that you win using the warrior wild is doubled. The following enhancements can also be gained during the feature:

  • Collect 2+ scatters, and you get a second set of five free games with all wild wins multiplied by five;
  • Collect 6+ scatters, and you get a third set of five free games with all wild wins multiplied by twenty-five;
  • Collect 12+ scatters, and you get a fourth set of five free games with all wild wins multiplied by three hundred.
