I was playing from a £10 no deposit bonus so I knew if I played a slot that required a minimum bet of £1.25 a spin it would literally be gone in under a minute - Lucky for me 300 shields allowed you to reduce your bet to the very minimum of 0.01p so a very decent 25p a spin.

I landed the free spins quite quickly but only manager to get to the second stage of the spins - but seeing that a possible 5 free spins were up for grabs with a x300 multiplier I simply had to keep playing it and it wasn't long before the free spins came in AGAIN. Still no luck though with the last stage of the free spins.

I was doing my wagering and winning little things here and there after about an hour of play and many sets of free spins later I finally got the winning set. Passed the first and second stage with flying colors and was up to the x25 multiplier and then I couldn't believe it I had collected enough shields to open up the final set of free spin with the x300 multiplier. I immediately shouted to my partner to quickly come and watch. In order to have the x300 multiplier you have to hit a win with the Wild Gladiator symbol - my second spin it was literally like a three symbol win with the wild and it gave me just over £130 (APPROX) I was so excited I had three more of these babies left to spin - thought I was finally going to take in my first million - didn't have a single win with the wild! Gutted - I think I won just over £150 from the set free spins - but this allowed me to meet me wagering and withdrew £100 from the no deposit bonus!


Since skill-on-net slots is really bad, and 300 shields it is not WMS, i believe this is nextgen game. It is also appeared at every casino which had a lot of slots, like guts casino for example, and there it is written microgaming quickfire. So i really can not 100% sure say who is owner for this game.

I like this slot, i believe we can put this game in line with dead or alive or break da bank again, but apart from this game, here is base game is super boring, even 5 wilds will not pay x 100 total bet, and this is sick. But on free spins, every player can get x300 multiplier for wins with wild, and 5 wilds with x300 multiplier will pay... I did not know how much it will pay, it will be awesome amount of money. I am not big fan on this slot, but i get few mins more than x 1000 total bet on this slot. But few times i lost around 200 euros on my account playing 0.25 bet, which is horrible experience of course.

Conclusion: Good game, but variance is very big. Also it is boring game, if you did not get free spins, there is nothing interesting to see and wait. 6 stars, for high variance.I think i had good time with this slot, as i told i get few huge wins, and overall i am win more than lose, but i try not open this slot anymore, after last two attempts with around 100$ at 0.25 bets and losing all my balance, i decide to stop feed this game.


Could this be a forthcoming favourite of mine? Who knows?! The graphics are very nicely done too, although not astonishing or astounding, and I love the swaying of the weeds (if that’s what they are) in the foreground, making me sway with the game! Up…down…win…lose! No star down or up.

A free spins feature that pays up to 300x your wins? OMG! I’ve never seen nor heard of anything like this before. It’s simply out of this world! But as always, there’s always a catch to it, and one of them is the extremely low paytable for all the symbols, except for the Wilds and the Scatters, purely to balance out the extremely high win multiplier. Very logical and makes good sense! The Wild symbol has a 1000x line bet win while the Scatter symbol pay up to 100x total bet amount. Now this is what I like – paying Wilds and Scatters – unlike most other games, and although they don’t pay very much by themselves, the possibility of getting them multiplied by up to 300x in the free spins can certainly result in super huge wins indeed! No star down or up.

The free spins feature game have 4 levels of achievement, each higher level increasing the win multiplier from 2x to 5x, 25x and finally up to 300x times bet amount! Super marvellous this! All you need to get is just 3 scatters to trigger off the free spins, and win 5x your bet amount. More triggering scatters would pay much more in wins but the free spins quantity remains at 5 free spins. Yes, it looks very little initially, but you’ll get more free spins quite easily during the free spins play. If you’re really lucky, you’ll even reach the 4th level and get 300x the bet amount for each and every win in the additional 5 free spins! This is definitely the best feature of 300 Shields. No star down or up.

The worst part is, I couldn’t make a win from the few attempts I played 300 Shields. But just as with Playtech’s game Dolphin Reef, timing and luck is everything, and I haven’t reach that stage yet. One day soon, I hope, I could start making wins on 300 Shields on a regular basis as I could with Dolphin Reef. I have a feeling that these two games are very similar to one another but on different platforms! Another super game from NetEnt, and one of the best too, but no win from me means 1 star down.


From all I have read and see some winner screenshots from this game I must admit I was really surprised what this game has to offer.

But of course there is a catch in that, seeing that this game can award X 300 of the bet amount yes, but you need to be extremely lucky to trigger that and that will happened if getting those 4 level shields in the free spins feature. The game has free spins feature but also 4 levels of it and to get those astonishing X 300 bet you need to get to that 4th level. I have tried to play this game several times.

The base game was awful, not giving me anything or only dead spins, I only once triggered the free spins feature giving me only 5 free spins. Have to say I was really disappointed of the amount of the free spins this game is offering, but of course if that feature awards you with X 300 the bet, there must be less free spins.

I have never reached that 4th level and I really want to reach it having those free spins with great multiplier is really great big amount of money. Well I hope someday or when will have bigger amount of money so I could play this slot. What made me playing this game seeing some nice winning screenshots, so I wanted to try, but I guess same goes as for the DOA and 300 Shields you need to play this game very often and spend much money and time to see some benefit of it? Great slot will keep on trying hopefully will hit something bigger.

do like here soundtrack, do like animations on shields and wilds, but nothing really interesting about what I would like to write.

Gameplay is absolutely boring and not interesting during normal play. All payouts are terrible low, and it is hard to get any even 10 bets win during it. I am hate to play this game when it just not giving feature, because money gone from account balance very fast.

Free games feature is very interesting and it is where is possible to win good money. Free spins triggered when 3 or more scattered shields appear anywhere. During free games there is multistage feature, which require to collect scatter to advance on new level. Each new level bring more multiplier for wins with wilds. 4th stage have x 300 multiplier with wilds, and this is where you should get awesome wins.

I am was at 300x stage only once. And it was terrible. When I hit it, my heart was beating like crazy, because I had 5 free spins with x 300 multiplier for wild. But I was always in tears when 5 free spins ended, and i do not have any wins with wilds after all. I had once more than 100 bets win, on 25 x multiplier stage, but it is of course should be much more better on x 300 stage. Most features for sure ending on first or second stage, and it is another pity fact.

I rate this game with 7 stars.

en I played I had only small winnings during base game, I expected to win more sometimes.

The free spins feature here is very interesting since you can win up to x300 multiplier. I had a few times free games, but the results were not so good. Around x30 bet every time, some time a little less than x60. To receive x300 multiplier you must collect shields. Each shield during free spins increases your counter, awarding additional free games with higher multiplier. I saw some videos where players got this huge multiplier at the end for 5 free games, but the payout was not so good since there where only low payout symbols on the reels.

This multiplier is hard to get. I played many times, but never received it. I think you need to have good bankroll to play this game. Many times I lost the money very quickly without having any free games.

Otherwise I like this game since the potential is good into feature. It could provide great big wins if you have luck on x300 multiplier for the last 5 free games. I like this game also because it is unique; there are no clones or something like this. I think I will play it even in the future, when I will have my balance in good ratio. I don't think I would play it if my balance is low, because it can eat your money really fast.

Even though I think this game was based on the movie 300 which has the legendary Gerrard Butler as an actor.

This games theme are based on war objects including the highest paid symbol being Wild which is a warrior. I like the animation of the warrior wild when it appears in a winning combination. This game game's 300x multiplier attracted me the most, because I checked out some videos and saw what this game could do with that multiplier on a minimum bet. The lower payout symbols are from a deck of cards with an arrow pierced through it. I have to say the base game payout is very low, even for 4 symbols and winnings are not that often either which is a downside for me.

3 or more scattered shield icons triggers the battle feature free spins. You are awarded with 5 free spins and during those spins you collect scattered shield icons. If you accrued 5 scattered symbols you advance to the next level with a higher multiplier and additional 5 spins and you have to repeat the same until you get to the 300 multiplier with 5 free spins. Now be aware the multiplier only awards when wild is in a winning combination.

I normally just get to 2 levels and out of the blue I was on 5 free spins with 300x multiplier and minimum bet. This was the moment of truth and I thought I would bag a decent win, make no mistake, not 1 wild in any of my winnings combination during those spins, extremely disappointed. Even gave this game a break for a few months as I kept of thinking what could have happened if I just had 1 win with wild and at least 3 symbols on a payline, even if it meant it was A or K symbol.

I would recommend this game and its worth a try and who knows maybe your luck will be better than mine.


300 Shields has 25-paylines and 5 reels. The minimum bet is €0.25 but I usually used to play it with my average bet size of €1 per spin. The wins during base game are somewhat limited. It often pays less than your bet size up to 5x bet size.

The warrior symbol is a wild while the shield symbol is the scatter. You need 3 or more shields to activate the free spins.
That's when the fun really starts and when you can see what type of potential this slot has. You only receive 5 free spins though in the beginning and a 2x multiplier for all warrior wins. But if you collect more shields you'll earn more free spins, and the multiplier changes from 5x, 25x up to 300x as you collect more shields.

In addition these free spins can be retriggered. It's really difficult to get the last stage, which has a 300x multiplier but that's the final goal. It's easy to win big with such a high multiplier. I never came further than the 25x multiplier though.

My biggest wins up to this day are 100x, 130x and 175x bet size from the free spins. Overall it's a really nice and exciting game to play with a theme I'm sure many appreciate.

Final rating for 300 Shields is 8/10


Honestly, this is probably my favorite online slot, and i love to play it, i play it every time i can. This slot can make you rich, i think it is had even higher variance then dead or alive from net entertainment. So, if you decide to give this slot a shot, here is my warning: better play at minimum bet, or 0.50 max, because ifyou decide to play at 1.25 per spin, this slot can take all your money in no time, and even you enter it with 1k$ on balance, it can eat this all and does not give you anything nice. Also you can become mad guy with it, due to really, absolutely high variance, even in free spins.

I should say that i love graphic and sound on this slot, and i love everything about it, really, i have a friend, who told me that it is his favorite slot. I decide to try it too, and now this is my favorite slot too. Everything with this slot make me nervous, because i had ABSOLUTELY CRAZY SESSIONS WITH IT. Sometimes i had 10-15 deposits without achieving last stage on freespins. Imagine... But usually then coming this x 300 multiplier ( last stage, to achieve it you need to collect 12 shields on 3 stages before, total it 15 spins, if you did not hit retrigger, so this is possible, hard, very hard, but come on, x 300 multiplier, of course it hard). My best win on this slot was 2.025$ on 0.50 bet. More than 4k x total bet. You can not imagine what i feel when hit it. I just stand up from my chair and start dancing xD

This is amazing slot. I love it. What else should i say.



The x300 Feature is almost impossible to get - I have had it once and never again and its not through the want of trying!


Like I said, many wins are very small, the Free Spins round is triggered with difficulty, and in addition there are similar slots much better than this.

Very low payouts during normal play. Feature is not guarantee anything. Even on x300 multiplier you can win small or zero.
