300 Shields review

300 Shields is most likely one of the most popular video slots coming from the NextGen Gaming factory. At first look the slot doesn’t seem like it has a lot to offer. But once you take a look at the bonus feature you will see that 300 Shields has the potential for massive payouts thanks to the maximum 300 win multiplier which players can get in the free spins bonus. This is the main reason why this slot is so popular at NextGen Gaming casinos and why it’s worth trying out for real play.

Theme and Visual Details

The theme of the game comes from the world known Spartan legend about King Leonidas and his army of 300 brave Spartans. The reels of the game are set in a wheat field in ancient Greece, but we can’t say that the visual details are on the top level.

But this is to be expected as 300 Shields is an older slot and the designers focused more on the payouts in the game rather than on the visual appearance.

Gameplay video


Like in many other NextGen Gaming slots the reels of the game seem to spin slower than in most other slots. This contributes for a slow gameplay which can be dull at times, since the base play payouts are not too impressive.

The only real excitement starts when two Scatters hit the reels and you’re eagerly waiting for the third one to strike.

Bet sizes and payouts

300 Shields is a 25 payline slot where players can place bets ranging anywhere from $0.25 up to $12.5 per spin.

As expected, the slot comes with a high variance and an RTP value of 95.29%, which is a bit lower than in most video slots.

Bonus features

The Wild symbol in the game is the Warrior and it comes with a maximum payout of 1,000 coins for landing 5 of them on a winning payline. The Wild Warrior can land on all of the reels and will replace for all of the symbols in the slot, except for the Scatter Shield symbol.

The Scatter symbol can also land on all of the reels and has a maximum payout of 100 times the total stake for landing 5 of them on the reels. But the fun starts even with 3 Scatters on the reels which trigger the Battle Feature.

When the Battle Feature begins, the player is awarded with 5 free spins where all wins with a Wild symbol involved will be doubled in size. The goal of the feature is to collect as many Scatters as possible and get to the last level.

If you collect two or more Shields during the initial 5 free spins you will get an extra 5 free spins where all Wild wins will be multiplied by 5. If you manage to collect 6 or more Shields in total from the first and second series you will get a third series of 5 free spins where all payouts will be multiplied by 25. The end goal is to collect 12 or more Shields which will award a fourth series of 5 free spins where all wins with a Wild symbol will be multiplier by 300.

This way all you need is one 5 of a kind win with a Wild symbol involved in order to get a big payout. The best part is that if you get 3 Shields in a single spin during the feature the current series is re-triggered with an additional 5 free spins. This means that you can get a big number of free spins in the last series and hopefully a big payout, thanks to the 300 multiplier attached to the Wild Warrior.


300 Shields is a video slot which will definitely catch your attention once you see what the bonus feature has to offer. The visual details and animations used in the slot are not too attractive, but there’s much more about this slot than meets the eye. With a Wild Win Multiplier ranging up to 300 players can easily score a big payout in the bonus feature, if they are lucky enough to reach the last level.
