About the Slot

300 Shields Extreme is a 5-reel online video slot with 25 paylines. NextGen Gaming have improved upon the sequel with this installment. The theme of this game is based on the 300 Spartans who fought against over 100,000 Persian soldiers in Ancient Greece. The game’s graphics and gameplay have been improved and, additionally, NextGen have included the chance to buy the bonus spins feature. This is where players get to win big on this slot.

The game features regular playing cards and a variety of additional symbols. These include ships, fighters, swords, arrows, a warrior, and a shield that represents the scatter symbol. Most of this game’s action happens in the bonus spins round. This exciting feature comes with an exciting 300x multiplier. If you are a lover of ancient or medieval combat-themed slots, this particular video slot is sure to be a perfect match for you.

Slot Technicalities

Playing and winning on this slot is straightforward and easy. All you need to do is select a bet for each line and then proceed to spin the reels. Additionally, you can win by landing three or more matching symbols on appropriate positions. Any time you land 5 warrior symbols (which represent the wild) on a pay line, you are awarded 40 times your total stake. It is important to note that the wild symbol substitutes for other symbols except the scatter symbol. Therefore, you can match the wild (warrior) symbol with any other character on a pay line to form a winning combination.

Furthermore, the scatter symbol is extremely important in this slot since it helps you activate the bonus spin feature. As stated earlier, the bulk of the game happens in this bonus round. Therefore, it is important to be on the lookout for the shield scatter symbol at all times. Apart from activating the special feature, the scatter symbol also awards multipliers when you land 2, 3, 4, or 5 symbols on a pay line. Two scatter symbols will give you 2x your stake, three, four, or five will give you 5x, 12x, and 100x, respectively. Additionally, you can choose to buy the bonus spin feature that awards 60 times your stake.

Slot Special Functions

On this slot, in the bonus spin feature, when you land 3 or more the battle feature will be activated. In the battle feature, you will get 5 additional spins and any winning combination that includes a wild symbol will give a 2x warrior wild multiplier.

Furthermore, you need to get as many shield scatter symbols as possible because the more shields you get the more multiplier you are awarded. For example, if you get 2 shields you will be granted a 5x warrior wild multiplier. If you get 6 or 12 shields, you will be given 25x and 300x warrior wild multipliers, respectively.

Although this video slot does not come with a progressive jackpot, players can still win big, most especially with the bonus spin feature where you can win up to 17700 times your stake on every spin. Playing with maximum stakes, you can win up to £222,125 playing on this slot.

You can also choose to play this game on mobile devices as this game is highly compatible and accessible across all platforms and operating systems. Be it an Android or IOS device, you can play this game anytime and anywhere you like.
