300 Shields Extreme Slot RTP, Details and Wager Limits

Reels/Paylines: 5 reels + 25 paylines

Stakes Range: 25p to £12.50 per spin

RTP: 95.3%

Max Win: 17,773 x bet per spin

The 300 Shields Extreme slot game is played on 5 reels with 25 paylines. Winning combinations are formed from left to right, starting from reel 1, by landing 3 or more matching symbols across any of the paylines. The exceptions are the wild, scatter, fighter and ship symbols where only 2 are needed to land a winner.

You can spin away from 25p to up to £12.50 per bet across all devices. The maximum used to be a little higher but this has since been reduced. Simply use the + and – buttons above and below the spin button to adjust your total bet.

The 300 Shields Extreme RTP is 95.3%, which is quite a way under the average of 96% for a slot of this type. In terms of variance, it’s on the high side, so don’t expect big wins too often.

The maximum win here is 17,773 x your stake, which is best achieved during the bonus feature where a 300x multiplier is up for grabs.

Theme – an epic Spartan battle

Theme: Spartan

High Value Symbol: Shield Scatter

Compatibility: Mobile, Tablet, Desktop

300-shields-extreme-slot-base-game

Visually, the 300 Shields Extreme slot is almost identical to the original, although the graphics and animations have improved in this version. Set on a rural hillside with temples in the backdrop, it has a calm feel to it and the game is loosely based on the blockbuster movie 300.

Symbols on the reels include Spartan style A, K, Q, J, 10 and 9 royals as well as arrows, swords, ships and fighters. The most rewarding symbol is the shield scatter, and 2, 3, 4 or 5 on a payline will give you 2, 5, 12 or 100 x your stake.

3 or more scatters will trigger the Battle feature where you’ll begin with 5 free spins. The Warrior is the wild symbol and substitutes for all symbols bar the scatter. 5 on a payline will reward you 40 x your total stake.

It’s worth noting here that any winning combination involving the Warrior wild will add a 2x multiplier to your winnings.

300 Shields Extreme Bonus Features

With a Spartan theme, it’s all about the Battle feature where wins involving the Warrior wild can lead to multipliers up to 300x. Players outside of the UK can also buy the feature, which we’ll expand on shortly.

Battle feature

300-shields-extreme-slot-battle-feature

3 or more scatters in the base game will trigger this feature. The key to the Battle feature is to collect shield scatters as these will reward you with more free spins as well as increased Warrior wild multipliers up to 300x:

2+ scatters 5 more free spins + 5x multiplier
6+ scatters 5 more free spins + 25x multiplier
12+ scatters 5 more free spins + 300x multiplier

If you land 3 shields during a free spin, you will get another 5 free spins in the stage you’re in. If you were to do this in the final stage, you could get a 300x multiplier.

However, getting to the final stage isn’t easy as this 300 Shields Extreme slot is as volatile as they come. But if you do manage it, there’s a huge 17,770 x your total stake to be won from every free spin involving the 300x wild multiplier.

Buy Pass feature

This feature is where you can buy your way into the Battle feature for 60 x your stake. But please note that it’s not available to UK players.

Originality








The main differences from the original game are the improved graphics and animations. Whilst this 300 Shields Extreme slot is recommended, we would like to have seen more bonus features added from the previous version.

We’d recommend trying the demo first to see if you like it. But if you’re a fan of highly volatile slots, this one might be for you.

Other slots to consider with a similar theme include WMS’ Spartacus Gladiator of Rome and Tiger’s Glory Ultra from Quickspin where the max win there is a whopping 32,464x.

Light & Wonder/NextGen Gaming has now released 300 Shields Mighty Ways. It comes with up to 262,144 ways to win, 300x wild multipliers and 30,000 x bet top payouts.

Pros
  • 17,773 x max win
  • Unlimited free spins
  • Great on mobile
Cons
  • Highly volatile slot
