300 Shields Slot Review
The Spartans are being characterized as a brave, strong & daring nation. They fought with sweat & blood. In the end, King Leonidas, who leads the Spartans, try to win to the last man, until they finally fall victim to an arrow barrage.
The Slot Machine has:
- 5 reels
- 3 rows
- 25 paylines (from left to right)
The adrenaline & old-school lovers should try this slot game. The displayed visuals are a little backward, but many players still like this type of slot machine. Since it was adapted to HTML5, there are more colors, clearer details & new game effects. It also has rewarding bonus features.
The Theoretical Return to Player (RTP) is 95.29% and the Volatility is high. This means the player will get not so frequent prizes, but in big proportions. A certified Random Number Generator (RNG) generates all the spin outcomes. So, the user can trust for sure the gaming provider.
The 300 Shields can be played on many best online casinos for fun or for real. “For fun” means that the player can make no deposits in order to spin the reels. It is a 100% free play. Not all slot sites offer the demo version of the game. “For real” means that the player deposits real money & gets real prizes. The maximum win is relatable to the slot’s title – up to x300 bet multiplier.

Symbols and Winning Combinations
The 300 Shields Slot has 10 regular symbols: 4 symbols after the Spartan theme & 6 card suit symbols. The drawn symbols are entirely matching the theme. The first 4 symbols are high-paying symbols, but the last 6 are medium-paying symbols. The Spartan & the Boat symbols payout even when 2 symbols pop up on the reels.
Game Symbols from the highest value to the lowest:
- Spartan Archer Symbol
- Boat Symbol
- Sword Symbol
- Arrows Symbol
- Ace Card Symbol
- King Card Symbol
- Queen Card Symbol
- Jack Card Symbol
- 10 Card Symbol
- 9 Card Symbol
The Spartan Symbol & the Boat Symbol have the highest value. Let’s place a maximum bet of $5. As a result, when 2 symbols land on the reels, the player gets $2. Then 3 symbols give $15, 4 symbols – $100, 5 symbols – $250.
The 9 & 10 Card symbols have the lowest value. If the bet is $5, 3 symbols award $4, 4 symbols – $10, 5 symbols – $100.
As in all slot games, there are special symbols, which initiate different bonus games & features. The special symbol is the Wild Symbol (represented by a warrior) & the Bonus Scatter Symbol (represented by a shield).
300 Shields Slot Game – Free Spins & Bonuses
The 300 Shields’ main bonus feature is the Battle Feature, which is a kind of a Free Spin mode with extra multipliers. In order to activate the Battle, at least 3 Bonus Scatter symbols must pop up. The player receives 5 Free Games (Free Spins) & all the wins are doubled. During the bonus game, more Shields will appear on the reels. More Shields – Greater Multipliers. The strategy is simple. All the Scatters are counted.
- 2 or more Shields = 5 Free Spins & x5 win multiplier
- 6 or more Shields = 5 Free Spins & x25 win multiplier
- 12 or more Shields = 5 Free Spins & x300 win multiplier
The Bonus Scatter Symbol not only triggers Free Games, but also payoffs:
- 2 symbols = $2
- 3 symbols = $5
- 4 symbols = $12
- 5 symbols = $100
The regular Wild Symbol covers all the symbols, except the scattered Shield. The Wild Warrior also payoffs:
- 2 symbols = $5
- 3 symbols = $25
- 4 symbols = $250
- 5 symbols = $1 000
The bonus program is not very complex, but the prizes are really rewarding.

The gambler can set the number of autoplayed rounds. The maximum is 100 rounds. The Autoplay can be stopped at any moment. Fix the Autoplay & relax!
The user can report to the casino’s Customer Service/Support about any bug or technical issue. The Customer Service can be attained via telephone number, e-mail, Live Chat, contact form, social media channel etc. The casino doesn’t guarantee saving the game progress in case the connection disappears, hence be sure to have a good & stable Internet connection.
