300 Shields Game Controls

300 Shields has an unusual approach to the game controls. While the buttons that let you spin and change your bet are to the right of the reels on the main screen, the Autoplay controls are tucked away in the settings menu, along with the paytable and audio options.

How to Win

You must land three or more matching symbols on a payline, left to right, to win.

300 Shields Maximum Payout

The most significant amount you can win from just one spin is 17,773x your bet, or $222,162.50, assuming you play with the maximum bet of $12.50.

Symbols + Bonus Features

The symbols on the paytable are a mix of battle-worn card royals and images of a fierce battle. 10 and 9 pay 1x your bet for five on a payline, Q and J pay 1.25x, while A and K pay 1.5x. The arrows and swords pay 2x your bet for five on a payline, and the ship and archer pay 2.5x. The Wild is a Spartan fighter that will stand in for any symbol besides the scatter and pays 10x your bet for five on a payline.

You will get five free spins. Each time a wild symbol is part of a winning combination, a 2x multiplier will be added.

Whenever a shield scatter lands during free spins, it will be collected in a meter to the right of the reels. Collect two scatters, and you will retrigger the feature for another five free spinswith a 5x multiplier now attached to the wild.

When you collect six shields during this second free spins round, you will get another retrigger with a 25x multiplier, wild this time.

To move up to the 4th level of the bonus feature, collect 12 shields for another five free spins, with a massive 300x multiplier wild.

RTP (Payout) and Volatility – how it affects your game

As a slot with high volatility, 300 Shields can deliver big wins only during the bonus feature. The RTP percentage indicates the amount you will likely win back from your bets over time. This game’s RTP of 95.3% is below the industry average but not enough to make a massive difference to your experience.

Audio & Visual Impact

If you ignore the old-school payline indicators, this looks like a slot that could be released today, with highly detailed gritty graphics and some bloody animations that give you a glimpse at the true horror of war. There isn’t much of a soundtrack, but you will hear the heavy rhythm of war drums every time you spin the reels.

Free Play or Demo Play

If you’ve visited an online casino, you probably know about slot demos. These are exact copies of real money slots, except you can use a generous supply of free credits instead of betting from your balance. Playing a free demo is an excellent idea because it takes all the risk of playing a slot for the first time and lets you learn the gameplay and features without worrying about your budget.

Is 300 Shields as good as the Best Slots out there? Let’s compare

Slots with themes about ancient times have an extra edge of excitement because it feels like you are stepping into major historical events. 300 Shields gets significant points for intense design and an innovative free spins round, but a few competitors look and play as good, if not better.

Rome Supermatch has an atmospheric theme and a unique game design where you unlock the rows of the game grid by landing matching symbols and exciting features like respins with sticky wilds. Augustus features Rome’s first emperor, breathtaking graphics, and wild reels that take you to new winning heights during free spins. Wild Link Cleopatra adds a mystical edge to the legend of ancient Egypt’s most famous female ruler and includes the Wild Link feature that expands the reels, adds multipliers, and gives you a shot at a vast, fixed jackpot.

My 300 Shields 25 Free Spins Experience

It didn’t take long until the reels started to cascade and I got a few small wins

300 Shield is well known for its popularity; in these 25 spins, inexperience will dive deeper and discover why. I began by setting my bet amount to £2.50 and began. The drums rolled, and the reels were spinning. After a few spins, I had won a few small wins of under £1, £2, and a £5 win. I changed my bet amount to £5 per spin and almost instantaneously won back £21. After this, I was consistently winning small wins, but I needed a big one if we were to get into profits, so I decided to increase my bet size for the last time to £6.25 and continued, but there was more of the same result at this bet amount and finished off the challenge in a loss.

  • Didn’t end in a profit.

300 Shields should grab your attention, especially after discovering its enticing bonus feature. While the visual details and animations may be less eye-catching, there's more to this slot than meets the eye. The Wild Win Multiplier, which can reach up to 300, allows players to land substantial payouts during the bonus feature, particularly if they're fortunate enough to reach the final level.

Pros and Cons


  • Intense theme
  • Rewarding multi-level free spins
  • High volatility means big wins


  • Lower-than-average RTP

Final Say – is 300 Shields worth playing?

300 Shields is an exciting and energetic slot with a lot to offer. I loved the gritty theme, but the free spins round was even more enjoyable. I don’t know if I’ve seen a 300x multiplier wild before, but it was a welcome surprise to know that it could help me land a massive win. This title is perfect if you like the rush of battle and high-volatility excitement.
