Bonus and jackpots for 300 Shields Extreme (Rating of 5/5)

300 Shields Extreme’s bonus feature is thrilling, not just for the potential of the 300x multiplier wilds but due to the graphics, music, and overall experience. If you choose the Buy Pass option, you can jump right into the action.

During regular gameplay, three or more shield scatters award you scatter wins and also trigger the free spins bonus round.

Battle feature free games

The sky turns dark, the sea takes on the pallor of death, and the enemy ships can be seen off in the distance approaching the shore. Shields stack up to the left of the reel set but are grey. For each shield that appears on the reel set, one shield is colorized to keep track of your progress. Your goal is to collect shields to win additional free spins and advance through the levels.

When you reach another level, a hoplite soldier appears behind the multiplier and thrusts his sword. You complete the spins on your current level before the multiplier shield is shot with an arrow, and the next level wild multiplier takes effect. You’re awarded five free spins for each level with the following multiplier wilds:

Level one: 2x
Level two: 5x
Level three: 25x
Level four: 300x

If three or more shields appear in one spin, it retriggers additional free spins on your current level. A full screen of one of the highest-paying symbols with multiplier wilds on level four would give you the maximum win of 12,000 times your total bet.

300 Shields Extreme graphics and visuals (Rating of 4/5)

300 Shields Extreme is true to the story in many minute details, including the background display of ancient Greek architecture, rune-shaped card symbols pierced with arrows, and symbols that include a Persian archer, a sword and sheath, an enemy ship, and flying arrows. A Spartan soldier, perhaps King Leonidas himself, is the wild, and the infamous round hoplite Spartan shield is the scatter.

The bonus round is not shy about blood. It spatters off the shield scatters, flows down the shield-stack level markers, and pours over the entire reel set with each spin. When combined with the cinematic music and film-quality sound effects, the intense graphics heighten the drama as you relive this legendary fight to the death.

300 Shields Extreme gameplay (Rating of 4/5)

300 Shields Extreme has such an exciting free spins bonus round that the main game can seem a bit dull by comparison. Without the multiplier wilds, the highest-paying pay-line wins are only 40 times your total bet, with five scatters paying even more at 100 times. This makes the Buy Pass feature so enticing because you can just keep playing the dramatic and exciting free spins round over and over.

What makes 300 Shields Extreme slot great

300 Shields Extreme has excellent graphics, immersive gameplay, and is action-packed. Some of the features that stand out include:

Multilevel free spins. Each level has wilds with increasing multipliers.
Multiplier wilds. The fourth level gives you 300x multiplier wilds.
Buy pass. Pay a flat fee to go straight to the bonus round.

How 300 Shields Extreme slot could improve

While 300 Shields Extreme is a meticulously crafted game, there are a few ways it could be even better:

Only two symbols are animated. Animations on the higher-paying symbols would heighten the game experience.
Only one bonus feature. Additional bonus features would add even more excitement.
The Buy pass is pricey. It may not seem worth it at higher bet levels.

Overall rating for 300 Shields Extreme by NextGen

300 Shields Extreme has amazing music, high-quality graphics, and a thrilling free spins bonus round. While the blood during the bonus round is a little gory, the game is a lot of fun to play. The Buy Pass option gives you the chance to forego the main game and get right to the heat of the battle. For great graphics, gameplay, and overall design, we give 300 Shields Extreme a rating of 4.3/5.
