Facts & Figures 

300 Shields is played on a usual 5x3 matrix, which has become a somehow standard set up these days. It features a solid number of 25 paylines, with an option to change the number of lines you play and in that way have better control over your bets. These are all common values, so we can't say 300 Shields slot in either good or bad. It's just average at this point.  

You can bet anywhere between £0.01 on a single line or up to £12.5 over 25 paylines. This makes 300 Shields a perfect slot for players on the budget since you can start wagering for just a fraction of a pound per spin. On the other side, high-rollers may want to avoid this slot, because max bet of £12.5 could be unappealing for players with bigger appetites.

If you decide to proceed with 300 Shields slot, note that there is autoplay as well. But it's as basic as it gets, with option only to set a number of automated spins, without the possibility to set loss limits or anything like that. 

300 Shields RTP 

300 Shields slot comes with a subpar RTP of just 95.299%. This is below an industry average, so if you plan on spinning the reel more than a few times, we advise you to move to some other slot with more favourable RTP. Our page about the best slots in the UK is a great place to start searching for high RTP games.

However, if you are not planning to play 1000+ spins, this shouldn't be a concern. Return to player rate is calculated over a huge number of spins, so it has almost zero effect on casual players. 

One more thing you should know is that 300 Shields is a highly volatile slot. It means that you won't score winning lines and bonuses that often, but once you get lucky, the prizes could be massive. Slots with high volatility usually give more winless spins, but also much larger single rewards, so make sure you keep this in mind before starting with 300 Shields.  

Game Design and Audio Effects 

300 Shields come with a nicely composed interface, full of intense colours and beautiful graphics. The overall design perfectly follows the theme of the game, with a lot of ancient motives on the screen. Back of the reels resembles the scroll of parchment, while the background looks like a hilly wheat field with classical Greek temples rising on the horizon. 

Some players may say that 300 Shields feel kind of outdated, which is somewhat true, especially when compared with the most recent slot editions. But we still believe that most of the people will find it quite appealing. 

Music, however, is much less impressive. Actually, there are barely any sounds in this slot. The only thing you'll hear is the upbeat drums when you spin the reels and some generic slot noises when there is a winning payline. If you like to hear nothing but silence while playing, 300 Shields is the game for you. 

In-Game Symbols  

Symbols in 300 Shields follow the overall theme of the game. Many recognisable ancient Greek objects are included, such as warships, swords, helmets, as well as famous Spartan foot soldiers and archers. Even the lower value symbols, like numbers and card signs, are designed to look like they have been written in the Greek alphabet. 

The wild symbol is one of the Spartan warriors, while the scatter is a shield. Special symbols have the usual abilities. Wild substitutes for all other signs except the scatter, and scatter is there to trigger the bonus feature, which we will talk more about in the following paragraph. 

Battle Feature Free Games

300 Shields have one bonus game named the Battle Feature. You can trigger it by landing at least 3 scatter shield symbols anywhere on the reels. Once you get them, you'll be awarded 5 free spins, and all wins that include warrior wilds are doubled. Watch for the shield symbols during bonus games, as they can get you more free spins and greater multipliers. This is how it goes: 

  • 2 or more shields - the second series of 5 free spins and all wild wins x5
  • 6 or more shields - the third series of 5 free spins and all wild wins x25
  • 12 or more shields - the fourth series of 5 free spins and all wild wins x300

Note that you can retrigger this feature. Every time you get 3 or more shield scatter symbols, there will be 5 additional free games waiting for you in the current series. As you can see, this bonus feature is quite simple, but with all that multipliers and possible respins, it can be very rewarding. But keep in mind that this is a highly volatile game, so don't get discouraged if you don't hit the bonus that often. 


300 Shields is a decent slot game. It's not too overwhelming, so both experienced, and novice players can enjoy it equally. Graphics are nice, and the bonus feature is very good, with both free spins and multipliers on the line. The biggest downside is the low RTP, but if you're just a casual player, that shouldn't worry you too much.

All players who love history-themed slot games should visit some of the NextGen casinos from our list and give this slot a chance. 300 Shields won't disappoint you!
