300 Shields Extreme graphics and design

300 Shields Extreme takes you right to the midst of the battle, with the blood-spattered reel set including symbols such as approaching warships, enemies poised to shoot, flying arrows, and rune-inspired card symbols struck during the melee. The scatter symbol is a battle-worn shield and the wild symbol is an animated charging armoured warrior with the word “Wild” sliding in blood across the bottom. If you’re a bit squeamish about the sight of blood, be prepared for even more during the free spins, when it pours over the reel set with every spin and slides down the stacked shields each time you reach a new level.

This depiction of battle stands in stark contrast to the background, which displays peaceful fields of grain, gently blowing in the wind around sun-kissed ancient Greek architecture. The professionally produced music and movie-quality sound effects add to the sense of drama. This is a very well-designed game, despite all the bloodshed.

How 300 Shields Extreme’s bonus features work

The excitement of playing 300 Shields Extreme is mostly found in the free spins during the battle feature.


The shield scatters pay the following multiples of the coin value:

  • Two shields: 2x
  • Three shields: 5x
  • Four shields: 20x
  • Five shields: 100x

Three or more shields activate the free spins feature.

Free spins

The free spins feature starts with five free games with 2x multiplier wilds. You can receive an additional five free spins either when three or more shields appear on the reel set or through reaching new levels during the battle feature.

Battle feature

When you start the free spins, shields stack up to the left of the reel set to keep track of your level, which has a corresponding multiplier for the warrior wilds. You advance by collecting shields to reach the following levels:

  • Two or more: five spins with 5x wilds
  • Six or more: five spins with 25x wilds
  • Twelve or more: five spins with 300x wilds

You don’t advance to the next level until all free spins at your current level are completed. If you re-trigger free spins with three or more shields at any point, your free spins are played at your current level.

Five-of-a-kind of the highest-paying symbols, the enemy soldier or ships, pays out 1,000 times your coin value or 40 times your total bet in the base game. Five soldiers or five ships that include a wild multiplier of 300x would give you 12,000 times your total bet.

Buy pass

During regular gameplay, you can go straight to the free spins feature at any time by paying 60 times your total bet.

Gamble feature

You can bet all your winnings to either match the colour of the suit of a face-down card, which pays 2x your winnings, or match the actual suit, which pays 4x.

Final thoughts on 300 Shields Extreme by NextGen

300 Shields Extreme is an action-packed, exciting game with great graphics, a fun game design, and awesome music. If you aren’t bothered by more blood than you’ve ever seen in a slot before, you’ll love this game. The only downside is that most of the action is in the free spins, but with the buy pass option, you can just play the free spins game if you prefer.

Looking at the pros and cons, we give this game an 8/10 rating.
