Where to play?

300 Shields is one of the most popular high variance video slots within NextGen‘s Gaming portfolio – don’t play it with a small bankroll because it will disappear like a paper in a bonfire. The 25 payline, 5 reel game is known as the ‘Multiplier’ online slots because the multipliers can be as high as 300x on a single spin!

”If you’re up for one of the most epic battles in the history of slots prepare for battle!”

High rollers looking for some excitement will be happy to hear that it won’t disappoint, it’s got spunk and grunt. Payouts are far and few in between but when the big win comes along the payout can be ginormous. The non-progressive jackpot offered by 300 Shields is 1,000 coins. The slots is based on the Hollywood blockbuster film ”300”. Under the command of King Leonidas of Sparta, 300 Spartans and their allies from other Greek city states took on the might of the Persian army at Thermopylae also known as the hot gates.

The bonus mode that enjoys centre stage is the ‘Battle Feature Free Spins’ (can be re-triggered) which awards up to 20 free spins. Triggering it is by no means easy so don’t tell us we didn’t warn you. The more shields you collect the more free spins you’ll earn and the multipliers will increase. The theoretical return to player percentage (RTP) is 95.3%. Symbols on the reels are cards from 10 to Ace (low value), trireme, swords, arrows, wilds (warriors), scatters (shield), multipliers and King Leonidas.

Game Play

The smallest bet per spin is 25 pence up to £200 while the coin range is 0.01 to 0.20. This is a highly volatile slots it should be played with a bankroll of at least £500. At an average bet per spin of £1+ we believe it’s enough cash in hand to trigger the free spins feature.


The wild symbol are the warriors they complete winning combinations when they substitute symbols adjacent to them bar the scatter.

Free Spins

When 3 shield scatters appear on the reels the free spins feature is triggered – 5 free spins with a 2x multiplier will be awarded. The more scatter shields that pitch the more free spins you’ll get and the bigger the multipliers. The free spins feature is divided into 4 stages:

  • Stage 1. The battle commences with 5 free spins with a 2x multiplier (all wins are doubled). Collect 2 shields to advance to the next level.
  • Stage 2. An extra 5 free spins will be awarded the multiplier shoots up to 5x. Collect 6 shields to advance to stage 3.
  • Stage 3. An extra 5 free spins will be given, the multiplier is now 25x plus there’s a wild symbol. In order to advance to the next stage you must collect 12 shields.
  • Stage 4. This is the main purpose of the game. Five free spins will be given, all wins along with a wild will have a multiplier win of an incredible 300x attached to it. Consider yourself luck if you get past the second stage. The slots is just as bloody as the battle of Thermopylae.



There’s nothing fancy about 300 Shields all we can say it’s one of the most volatile non-progressive jackpot slots we had the pleasure of reviewing. Despite it’s nerve racking volatility it’s popular with players looking to strike gold during the free spins feature.
