300 Shields Technical Features

NextGen Gaming released 300 Shields in 2014. This slot is inspired by the Battle of Thermopylae, in which an army of 300 Spartan warriors took on an invading army despite the insurmountable odds against them. The slot’s design is steeped firmly in the story of the Spartan forces and its Ancient Greek setting. 

300 Shields is played on a 5x3 grid with 25 paylines, though you can adjust the number of active lines. 300 Shields has an RTP of 95.29%, and is considered to have a high volatility. You can bet between £0.25 and £12.50, and choose to play with 1 to 25 active paylines. The maximum win up for grabs is 17,770x. 

The symbols include a Spartan warrior, a sword, and arrows. The top-paying symbol in 300 Shields is the Warrior: match 5 on a payline to win 1,000x your bet. But the Warrior is also the Wild, and substitutes for every other symbol except the Scatter. 

Standard royal symbols award the smallest prizes. Land 5 Ace or King symbols to win 150x your stake, while the Queen and Jack pay up to 125x. The 10 and 9 are the lowest-paying symbols, offering 100x for 5 of each.

300 Shields Bonus Features

300 Shields includes the Battle Feature Free Games bonus: land 3 or more Scatters (represented by a shield) to activate it. You’ll receive 5 free spins, and all Warrior symbol wins will be doubled for the duration of the round. You can retrigger the free spins if you land another 3 or more Scatters, too. 

A shield meter will appear on the left-hand side of the screen during the Battle Feature Free Games. Landing Scatters on the reels will fill the meter and bring you the following prizes:

  • 2+ Scatters: Win 5 free spins and multiply all Warrior wins by 5.
  • 6+ Scatters: Win 5 free spins and multiply all Warrior wins by 25.
  • 12+ Scatters: Win 5 free spins and multiply all Warrior wins by 300. 

If you reach the top level on the meter, you could win the top prize of 17,770x your bet. 

300 Shields Theme and Design

The Battle of Thermopylae is one of the most famous stories of the Spartans of Ancient Greece, and it’s an intriguing choice of theme for a slot. 

NextGen Gaming has used a colourful visual style for the background, symbols, and reels. The detailed images of the Warrior, Bowman, Boat, and Arrows all look great, and the background shows a picturesque rural setting with recognisably Ancient Greek structures in the distance.

300 Shields includes strong sound effects, especially the drumbeat that accompanies each spin of the reels. Animations are used well, too: watch the Warrior Wild swing his sword and the Bowman shoot an arrow when they form part of a winning combination.

Conclusion and Verdict

300 Shields is a visually impressive slot with simple gameplay and a distinctive Free Spins feature that incorporates a thematic shield-collecting aspect. You may retrigger your free spins if you land enough Scatters, too, giving you potentially many free attempts to win. 

300 Shields also has some big payouts, with up to 17,770x to be won. With all this in mind, we highly recommend that you try 300 Shields, whether you’re familiar with the story behind it or not.
