300 Shields Extreme Slot Online

A lot of slot games have been published and reached cult status. Slot companies see them as an opportunity to release a sequel. This is exactly the case with 2014’s NextGen Gaming 300 Shields game. So, now the company has decided to release a brand new edition called 300 Shields Extreme slots. In this review, we will talk about the game in full details, and try to uncover to you everything that you need to know in order to play this exciting online slot game.


Based on the famous movie called 300, NextGen is now launching a new edition of the Spartan themed slot game, with excellent graphics, smooth, dynamic gameplay and a lot of exciting bonus features.

It is based on a 5-reel, 25 payline concept and the developers have made sure that it is available on every device possible. Also, interesting enough the least amount you can stake in the game is £0.25, while the maximum can be up to £12.50, which makes this slot perfectly suitable for every type of slot players. Also, it is worth mentioning that it is a highly volatile slot game.

The graphics are quite different and upgraded from the original, and the game looks a lot better than its predecessor.

The symbols in the game are the same as the ones used in the original like 9, 10, J, Q, K, and A, which represent the low-valued symbols, while the higher valued ones include arrows, swords, battleships, and archers. The Warrior is the wild symbol and can substitute every symbol except for the scatter.


Many players would say that this game is quite similar to its predecessor, and we think that this is a positive thing since the 300 Shields game is a straightforward game and extremely user-friendly.

After you have chosen the desired casino, you will have to set the desired coin denomination or your bet in the game.

The game includes the “Autoplay” button which allows you to have more relaxed and enjoyable gameplay, while the “Bet Max” button gives you the opportunity to stake the maximal stake that you have available. We advise you to be careful with this option as it can drain your money very quickly.

Bonus Features

This game includes a single bonus feature which is the free spins feature, and it is triggered if you manage to land 3 or more scatter symbols on any active reel. After you have managed this, you will be awarded 5 free spins and an x2 multiplier. If you add 3 more scatters, you will trigger the feature with 5 additional spins. Every scatter shield symbol that you manage to land on the reels during the free spins will increase your shield count which works as follows:

2+ collected shields – 5 free spins with all Warrior wild wins multiplied by 5.

6+ collected shields – 5 free spins, with all Warrior wild wins multiplied by 25.

12+ collected shields – 5 free spins with all Warrior wild wins multiplied by 300.


300 Shields Extreme slots are relatively average when it comes to the RTP. The average percentage of an online slot RTP is 95.00% and this slot game has exactly 95.30% RTP, meaning it’s a little bit above-average. So, there is a lot to look forward when it comes to this online slot game, and with some amount of luck, you will be enjoying yourself with some pretty lucrative cash prizes!
