King of Slots is 5 reels and 26 pay-lines video slot powered by Net Entertainment software. This is a fairly simple slot inspired with the glitter and wealth of royal life. The reels are set on some kind of a black steampunk machine, against the background of a blue sea as seen from above. Give this fun slot a spin here for free or visit any of the NetEnt Casinos if you wish to play for real money.

Before you hit the reels of royalty, you need to set your bets. Coin denominations go from 0.01 to 1, and can be set by arrows in "Coin Value" section. In "Level" tab, you can set the number of coins per line. By clicking on "Max Bet" you will set the maximum bet available. "Spin" button is represented as the two circular arrows, and it will set the reels in motions, and "Autoplay" will turn the reels automatically for a chosen number of times without interruption.

Wild symbol in the game is the Blue Gem, and it can substitute for all the symbols except for the Scatter. The Scatter symbol is represented as 3 purple Gems, and if you hit 5 or more of them you will trigger free spins.

The number of Scatters will decide the number of Free Spins that you will get, and it is possible to get more than 5 Scatter due to Sticky Win feature. For 5 Scatters you will get 10 spins, for 6 you will get 15 spins, for 7 scatters you will be awarded with 20 spins. With 8 Scatters you get 25 Spins, and should you hit between 9 and 15 Scatters, you will be awarded with 30 Free Spins. All Free Spin wins will be tripled.

Sticky Win feature is triggered whenever you land a win on a bet-line, or 3 or more scatters anywhere on the reels. The winning symbols will be held, and locked in place while all other reels re-spin. As long as there are wins to be made, the reels will keep on re-spinning. When there are no new wins to be generated, the feature will end, and all active wins will be paid out.

King of slots is a NetEnt production slot. When I first saw this slot I tried it and I always had cold sessions on it. I think I prefer jack hammer over king of slots, however jack hammer hasn’t been giving me good wins lately, especially tournaments.

The slots have 25 paylines and minimum bet set at $0.25 per spin. The slot has a fruit base thing these in terms of symbols with standard card deck symbols. The pink colour looks okay, but I must admit when playing this slot, it looks boring accept for when you win big, you have some excitement inside you.

The slot has a sticky re-spin feature whenever you create a win, the symbols in the winning position hold still while the re-spins occurs. If another symbol of the same kind occurs on a payline creating another combo is created for bigger wins. You can get up to a full screen of symbols for the big win. I normally this notice with card deck symbols, very difficult to get full screen with premium symbols.

The free spins is triggered when 5 or more scatter symbols land on the reels. You normally get 3 scatter symbols and they on hold while the re-spins occur to find more scatter symbols to trigger the free spins feature. Between 10 – 30 free spins are awarded depending on how many scatters you get on the reels. During free spins all wins has x3 multiplier. You can really win big.

I am not a big fan of this slot, because I never really hit big on it, but I won x200 a couple of times. Triggering the free spins take forever as well. The game can get very cold at times, so keep in mind this is a medium to high variance slot. I do not play this slot often, simply because it bores me most times, unless I set it to auto play. You know you sometimes want to watch the reels spin whenever you play.

King Of Slots by NetEnt, was released about 2 years ago, but I only got to play it several months later, and that too was because I was given some free spins from my regular casino to try it out. There's nothing new about this game, it's just yet another cloned game, and with numerous other similar games from various other providers. It all boils down to which game you like best, according to your own preferences and tastes. As for me, King Of Slots is only acceptable, not outstanding in any way, with less than interesting graphics, and not even attractive enough with its average payout potentials. Inspite of all that, playing the game can be quite fun when the going is good, and with some decent payouts.

The best feature of the game is probably the Sticky Wins Respins, available both during base game play and during the free spins too, whereby the winning symbols are held in position whilst the other symbols take a respin. Each new winning symbol then becomes sticky too and another respin is given, for as long as there are new winning symbol/s appearing in each new respin. Yes, it is therefore possible to get all same 15 symbols for the maximum win for that particular symbol, although I have not seen any of such wins on any high paying symbols as yet. Have I got any such win yet? Nope, not even anything as close to it as yet! Sheesh!

Looking at the paytable, what greet your eyes, for those who know about paytables that is, would make you frown. The Wild symbols do not pay anything for themselves, and do not double any wins either. Likewise, the Scatter symbol, which normally would have at least a 100x total bet win for getting 5 of them, do not pay anything either, thereby greatly reducing additional winning chances from these two symbols. Only the Sticky Wins Respins could compensate for these omissions, but as far as I know, it hasn't lived up to its expectations as yet, and probably never will, who knows.

If the base game payouts couldn't give any decent wins, then the Free Spins games would, and could. 5 Scatters would trigger 10 free spins with all wins tripled, which is not bad, but not that good, but getting 9 or more Scatters would award 30 free spins, for a greater chance of making big wins. More free spins can be retriggered, and that is good. If the Sticky Win Respins occur on many of the free spins, then you can expect to get a handsome win at the very least. My luck on this game has never been that good, managing to get only a best win of 137x my bet amount, still very far away from a good win.

King of Slots nice looking video slot. Created by NetEnt exclusively for Casino Saga. And like it always happen after some time, King of Slots became available across other reputable casinos. When they announced this release I was thrilled and couldn't wait to give it a try. Now when I look at the game, it doesn't look so fancy like it used to when I first saw it. This video slot is not king amongst slots but it surely looks royal with crown and golden details. It's a 5-reels, 25-pay lines and minimum bet is 0.25 cents. Graphics looks fine. This game symbols are fruits but letters dominating the game.

This game features Sticky Win and it's triggered if you collect 3 or more Scatter symbols. Reels with winning symbols are held in place while all other reels re-spin for a chance of winning combination. Reels will stay in place and game will re-spin as long you keep getting winning combinations. Wild symbol substitute for all except for the Scatter symbol. Wild has no payout attached and its a huge minus to this game addition. Same goes for Scatter symbol. No payouts attached to Scatter but if you collect 5 or more Scatters there is between 10 up to 30 Free Spins up to grab.

Except for the Free Spins I have received I never used my pocket money in order to play this game. My game session were terrible and I never hit the feature. I haven't had chance to get familiar with this video slot and I doubt I would ever play it again. I really wish I made some success but it was my luck which said: 'No', not this time. I can't tell that I saw some winning screenshot on forum however someone must win this game. And I don't like this game like I did on the first sight.

King of Slots has a big name to live up to, and being a NetEnt game I have to say I didn't have the highest of hopes when I fired the game up for the first time. This time around though I was pleasantly surprised and whilst it's not my favourite game and certainly not what I would call the king of all slot machines it is certainly an enjoyable that should find many fans amongst on-line gamblers.

The reels in this game work in a similar manner to the Jack Hammer games but despite the fact there are only 25 paylines in this game I didn't find myself hitting a great number of combinations that looked as if they should result in a win yet did not. I think this may possibly be a result of the game having a relatively low number of different symbols on the reels. Each time a winning combination lands on the reels a free respin is awarded giving you a second chance at adding additional symbols to your paylines. The graphics representing this are very simple with winning symbols locking into place and lighting up making it very clear which symbols are part of your win and which symbols your hoping will appear on the next respin.

The basic payouts are not the best with just 40x your stake paid out for a full line of the top crown symbol however the design of the game makes wins on a large number of paylines simultaneously quite likely and there is also a 3x multiplier in the free spins mode giving this game a maximum possible win of 3000x your bet - not super high variance but enough to interest and excite most slot players I would imagine.

One thing that did catch me out playing this game was spotting three scatter symbols on the reels just before the game fired off a new spin. I wondered why I hadn't been awarded the free spins but after checking the paytable it turns out that just like the Jack Hammer games you need at least five scatters in order to receive the bonus in this game. I guess that is fair enough considering the reel setup allows for a full screen of 15 scatter symbols should you be unbelievably lucky! Additional free spins up to a maximum of 30 are awarded for hitting more than the minimum five triggering symbols and six or seven do appear quite regularly so I'd say this setup is fair overall.

The King of slots is a royalty of wonder comprising of 25 paylines, scattered gems, fruit symbols, and letter number combinations. For those of you who happen to like Jack Hammer and Jack Hammer 2, this will be your liking as a royal luxury type theme rather than the old astonishing comics. Unlike Jack Hammer and it's brother, King of slots do not have a mini story to tell the players. With King of slots, any 3 of a kind win rolls the carpet away for a sticky re-spin for the corresponding symbols where each symbol of the same kind puts another re-spin to play. It is highly possible to win an entire screen of symbols....including scattered gems!

King of Slots is better off being played on $1 - $1.50 a spin as the occurrence in hitting symbols become more discernable in my sessions. I was extremely ecstatic when 10 scattered gems went in to fill the reels but to the conclusion of them all, I was left with silence that I did not deserve. 30 Free spins that resulted in nothing.....how could that be!? My mood could have changed if these scattered gems paid me and well, I would not have been too disappointed!

I prefer the sleek style and the slow music notes of King of Slots, it makes me jam & think throughout my game play! Despite the cursed 30 free spins at 3x I once had, two of my stars will be taken away. I was lucky with other games but King of Slots did not gather my interest of what it would be like to sit on a throne! I will be giving this a 7 out of 10!


I had the biggest curse of having 30 free spins at 3x for 10 scattered gems during which the bet I set it to was I believe somewhere within $1 - $1.50 or perhaps bigger. I do not have the screenshot anymore but luckily I posted it on the thread for the worst screenshot before it got erased! I played through them all without hitting any type of wins on them!!! That was completely one of the worst moments I had and furthermore, these scatters do not pay anything!!! A complete miserable shocker of a feature that is embedded in my mind for a long time to be disinterested to try King of Slots again. Crown symbols are the hardest to get which questions my knowledge as to why these are tougher than finding the scattered gems. Weird eh!

Netent Entertainment has released another, well not so new game, because after this slot they had few others, with 25 paylines and 5 reels where the bet starts from 0.25 cents. The game has classic symbols as fruits and jewels, combined with crowns, some letters and number symbols where they have the lowest payout and of course the sticky wilds and the scatters.

Looking at this game it has so much in common with Jack Hammer and Jack Hammer 2 because they have the same wilds or sticky wilds feature and the same counts for the free spins feature. So another game from this provider which they only copy this game but only changed their symbols and of course Jack Hammer has potential of big wins, as for this game I can say the opposite thing.

I have never been lucky while playing Jack Hammer games so I didn't expect that I would be on this one. When they released this slot game there was plenty free spins offered from some casinos so we can try this game,but i was getting offers from some casinos as well for some tiny deposit to get 50-100 free spins on the above mentioned game.

Trying this game and I have tried it many times, it seems that the free spins feature is a bit difficult to be triggered, but even so if I managed to triggered the free spins the payout of this game was disaster. As for the sticky wilds I can say the same, even if I triggered them on the reels, always triggered the letters or numbers and not even once I had triggered something different for example the cherries or the lemons.

The King of slots video game is definitely a game I will never play again, well maybe offered as a free spins feature, but for real money I don't think that will happen and as I said I was never lucky neither had decent wins from it and from its sister games.

NetEnt is one of my favorite provider, but recently I see many new slots that are released which are identical to some of the nice oldies slot they had. I do not know if they have luck of new ideas for slots and features but releasing exact copied of old slots, changing only the graphics and sound, not even changing the pay table of the slot is very negative for them. Furthermore not even one slot of these copies is better on terms of sounds or graphics design, they are all worst, cheap replicas.

One of these slots is the King of Slots which is the same slot as my favorite Jack Hammer which I play most of the time and enjoy very much. Well I got many free spins for this slot when it was released and probably they were the last spins I played on this slot. Very low graphics, no theme at all and symbols that do not connect at all, letters, fruits, jewels and crowns, simple a mess.

The game play is entertaining since there is the sticky win feature, where after a single win, you have respins until there is a no winning combination. I like this feature a lot, I find it very exciting and keeps my adrenaline at high levels. The slot has also free spins, which you can win with 5 or more scatters. The sticky win feature is active here too, so if you have 3 or more scatters on the screen there is a respin in order to get more scatter symbols or another winning combination. Also the winnings of the free spins are multiplied by 3 which is great.

The pay table of the slot is not very good as the 5 of a kind of the best symbol, the crown, pays only 1000 times the coin value. The slot is medium variance, it cannot produce huge wins, but on the other hand you can have a streak of many big wins on a row.

King of Slots is one of the newest video slots on online casinos. The game has 25 paylines and it is very similar to Jack Hammer slot. I should not say similar, this game is a clone which came from Jack Hammer. When I first saw it, I did not like it.

Many casinos gave some free spins and I used it of course. I won only small amounts, but hey those are free spins. I did not expected any big win from free spins, but 1€ or 2€ could be good to spent it on Starburst game. I tried to play it with my own money too, but only around 10€.

I spent it pretty fast after I received free spins. When you get 5 scatters like as at Jack Hammer the feature starts. During free spins winnings are at x3 multiplier. When I played it, I won around x30 bet from free spins. Later I raised my bet and I busted. I think this game is not so good, because there are already a few game of this kind. I like sticky win spin, but I still prefer to play Jack Hammer.

This game could also provide some good winnings, I already saw some bigger than x200 bet, but I had better feeling when I played Jack Hammer, both versions. For me even barber shop from Thunderkick software is better, funny than this one.

King of Slots really dissapointed me. Since it is a clone, I expected huge big paytable that could provide bigger wins. But no, all are almost the same as at previous games. I would really want to see something new from NetEnt. This is only a bad clone game and I will not play it again. I prefer to play other, older games which are more unique than this one.

King of Slots is a game from Netent software and it was released in many casinos earlier this month. I had many free spins promotions but in none of them I won anything more than few cents, so I decided to try this game with a decent bankroll.

This game has 5 reels and 25 paylines and the minimum bets are 0.25€ per spin. I spent a long session with this game and I have to say I don't like it. This game reminds me of many other games, like a bad version of Jack Hammer slot, and it all is because of sticky win feature. It is triggered when you get a winning or 3 scatters, then you'll get a respin with a purpose to increase your results and feature ends when there's no new winning symbol. There are wild symbols also, that substitute for all except scatters, but from my experience, not very often they help making winnings.

First of all, I am not a fan of the design for this slot. It has random symbols- fruits, jewels, letters, it kind of seems like there's not any thought put into it. Another reason why I don't like this game is because I've experienced so many empty spins it gets me frustrated. And overall the biggest winning I've had on base game, when most part of the reels were covered with matching symbol has been around 15x bet.

So as a bonus round this slot has free spins. I've had free spins on this slot a few times and they have been very disappointing. First of all I dislike the fact that to get free spins you need to get at least 5 scatter symbols, it is quite hard. Besides, even when you have 4 scatter symbols, you don't get paid. For 5 scatters I received 10 free spins with 3x multiplier, it is a decent amount for free spins and there's the sticky win feature as well. Reason I don't like the free spins too is because all the times I've had them, half of them are empty and I haven't got over 30x bet winnings even with the multiplier. And this win came from 15 free spins, not 10, so that is even more upsetting.

Overall I don't like this game and I don't recommend it. The design is average, sticky win feature usually gives 2x-5x bet winnings so I think you need to be really lucky to win something decent. There are many better games than this and I won't be playing it again.

King of Slots was exclusively created for Casino Saga and after this game went live, I was quite disappointed because my country is restricted and I couldn’t play nor try out the new game.

Any player get excited when there is a new game especially when it comes from one of the favorite software like NetEnt is to me.

I could tell that I completely forgot about the slot until I saw topic in forum here and I was happy to try it with my real money and bonus I received from Fruity Casa Casino!

Unfortunately, there was no excitement and I have not unlocked any feature.

My game session turned out horrible. I played on the min.bet size which is 0.25 and my biggest win was not to exceed x 10 my bet size.

I must tell, I expected way more then what I saw. But now, thinking of my last sentence, I am not sure what would I change there?

I had no luck at all which would add a note of excitement and I am pretty sure I would be way more happy with this slot if I had win, or at least free spins, but non of the mentioned above happened.

Kings Crown fell on me and I can feel its heavy and not that shiny as I thought.

There isn’t single symbol that I liked, which is unusual but it does happen sometimes.

My minor wins came from symbols 10 and J !

I collected 4 symbols of 10 on the 1st. payline, one on the 2nd reel,and four on the 3rd payline and that was the moment when I become excited but that was only for the short time.

That was my first time ever and I will not say this game is terrible only because I didn’t like it.

The best thing is to try this game yourself and make your own opinion.
