The Design

It is a ‘normal’ slot with 5 reels in which 3 symbols will appear per spin. Furthermore, a beautiful and natural landscape can be seen in the background. To the right of the slot machine you have the ‘spin’ button and there you can also go to the menu or change your bet. At the bottom of the screen you will see your current balance and the bet you have selected. Once you have reached 1 or more paylines, an extra option will appear on the screen. More about this later.

How does 300 Shields Extreme Slot work?

The game works the same as many other online slots. The aim is to achieve as many paylines per round as possible and to win prizes. There are 25 possible paylines. It is also possible to clear the bonus round by getting 3 shields in 1 spin. You only need to press ‘spin’ per turn. It is also possible to run this process fully automatically.

How do you play 300 Shields Extreme?

First you choose a bet with which you will play per spin. The bets you can choose from are: 0.25, 0.50, 0.75, 1.00, 1.25, 2.50, 5.00, 6.25, and 12.50. Then you press the ‘spin’ button per turn, or you let it run automatically one after the other. Prizes and the bonus rounds can be won by completing the paylines or obtaining multiple shields, but more on that below. When you fall in prizes in a certain turn, there is also an option to make the prize higher. You can then gamble about the color / symbol of a card. By betting on red or black you can double the prize. By betting on the symbol of the card you can quadruple the amount. If you don’t make the right choice, you don’t win.

The Prices

The prizes depend on which and how many paylines you complete. Another factor that determines the amount of the prize is the symbol with which you complete it. Furthermore, the amounts you can win are adjusted to your bet per spin. The real big prizes can of course be won in the bonus rounds.

The Symbols

The ‘normal’ symbols are 10, J, Q, K, and A just like in a card game. As always, you have the Wild/Joker that helps you complete paylines. When you reach a payline with no less than 5 Wild symbols, you win 40x your bet! The Wild is depicted with a warrior. Other symbols include the Ship, the Sagittarius, the Swords, the Arrows, and the Shield. When you complete a payline with 5 of the last mentioned symbols, you win 10x your bet. As mentioned, you can unlock the bonus round with 3 Shields.

Bonus Rounds

In addition to a cash prize up to 100x your bet amount, you also get 5 free spins with a multiplier of 2x. Then you will collect extra Shields. Besides extra spins, these also yield extra multipliers. The ultimate prize is a 300x multiplier that you can achieve with this! The bonus can be divided into three levels:

  • 2 extra Shields: 5 extra spins, and a multiplier of 5x.
  • 6 extra Shields: 5 extra spins, and a multiplier of 25x.
  • 12 extra Shields: 5 extra spins, and a multiplier of 300x.

12 extra Shields: 5 extra spins, and a multiplier of 300x

300 Shields Extreme Buy a bonus feature

Nowadays this possibility can be found in many more games than before. It gives you the opportunity to ‘buy’ the bonus round, so that you can continue playing immediately. This game costs you 60x the bet you actually play with. So if you have 1 euro as a ‘normal’ bet, you pay 60 euros. Then the prizes you can win are adjusted to the 1 bet. On average, you often have to pay 80 to 100 times your stake for this, so in that respect this is an attractive offer. Earlier we mentioned the RTP of this game, and it was between two percentages. The reason for this is because the former percentage of 95.29% applies to the normal game, but once you use the buy a bonus feature it slightly increases to 95.69%.
