The Spin Lab

The Spin Lab

Fancy cooking up some crazy free spin science? Want to see if you have the power to experiment with some huge casino wins? If so, then you could certainly fall for the chemistry offered by NextGen’s The Spin Lab mobile slot game.

This machine gives you the chance to build your very own bespoke bonus round in a test environment that comes complete with a ton of colourful graphics, whizzing and banging sound effects and top notch base game dynamics.

What can I Expect from the Spin Lab Base Game?

Even though we’ve billed The Spin Lab mobile slot game as one of the greatest and most innovative titles released in 2015, this game does have a number of features that are of course typical of any mobile based slot machine. You’re looking at a standard base game that utilises a five reel set up together with a twenty five pay-line structure. In addition to this the game uses wild symbols to help you complete your winning combos and you can find your way into the bonus round with three or more scatters.

How does The Spin Lab Bonus Work?

Stop in three scatters anywhere in view to land The Spin Lab mobile slot bonus round. This takes you to a second screen bonus where you get to select one of three special features from three different categories, giving you the choice of 27 different bonus permutations. These govern various elements of the slot including how many of the high paying cube symbols appear on the grid and the manner in which the wild symbols function. Quite unlike anything you’ll find on any other mobile slots game, this experimental element sets this NextGen production apart from the other casino test subjects.

Which Special Bonuses should I Choose?

It can be hard to decide which extra bonuses you should choose for your free spin round on The Spin Lab. One thing is for sure some extras work better than others. For instance we have always found the extra wilds to not consistently offer you any more wilds than you usually see on the reels. Other bonuses work well together – stacked wilds and stacked cubes seem to complement each other and produce some great results. However, our best advice to you here is that this is a process of trial and error and you can best work out what’s going on with a good old fashioned slice of free play.

Why Should I Play The Spin Lab?

If you have ever wondered what the smartphone slot development story might look like then The Spin Lab mobile slot game is definitely a game you should entertain. There is tons of action in the base game as you would expect from any mobile title that we’re recommending on the site, but the bonus game is a real class act.

There is something incredibly satisfying about playing around with all the different options on offer and seeing what kind of effects they have on the wins. In addition to this it’s not like all the action is stacked in favour of the bonus either, with plenty of good wins and weighty prizes available at every level of play.

High Society

High Society is a mobile slot game that can take you up to the skies. This fast paced twenty line title from Microgaming is geared up around its dual free spin round feature, which uses some innovative wild reel and locked wild techniques to help you bring in the cash.

Don’t be fooled by the classic base-game formula on offer from this slot, there’s a whole load of reel powered action waiting for you when you hit the bonus round, and with a pay-table that’s weighted towards the big combinations, this is one game that will keep you coming back for more…

How does the High Society Base-Game work?

The High Society base-game is very simple. This uses a classic five reel slot set up featuring twenty pay-lines giving you a format that’s instantly recognisable and immediately accessible. There are plenty of big wins available here with the top jackpot awards coming in at four thousand, five thousand and six thousand coins. However, it’s not just about the combination wins – there are a couple of special symbols to help you rake in the wins here. These are as follows:

– High Society Wild Symbol – These appear on the first and last reels of the slot game. They operate in the standard manner, substituting where-ever possible on the reels for any other symbol in the game, barring the bonus scatter.

– Money Scatters – Stop in three of these symbols anywhere in view on the base-game grid to take you into the free spin bonus round.

What is the Bonus Game Activation process in High Society?

High Society features two different free spin rounds. These are activated in the same manner – simply stop in the three scatters needed on the base-game grid to enter a second selection sub-screen. Here you get to choose from the two brilliant free spin rounds on offer from this slot. If you want to know what to expect from each round we’d suggest you try this title out on free-play and you can find the one that suits your playing style the best.

How does the Super Wild Bonus work on High Society?

The Super Wild bonus is the first bonus available on High Society. The more scatters you use to activate this round, the more free spins you’ll receive on the special reel set on offer from this cool feature, up to maximum of 20. During this bonus if you can stop in a wild symbol on the first or last reel of the game it will expand to turn the entire reel wild, giving you an opportunity to stop in some massive multi-line combos. You can even re-trigger the bonus here by stopping in wilds on both the first and last reels in view, adding a further ten spins to your count.

How does the Super Multiplier Bonus work on High Society?

No matter how many scatters you use to activate this bonus round you will always receive ten free spins. These take place on a special second set of reels where an incremental multiplier is applied to all your prizes – the more scatters you use to activate the bonus the bigger the multipliers on offer, which can reach as high as 10x. You can re-activate the bonus here too, by hitting wilds on the first and last reels on the same spin, which will add a further ten spins to your count.

300 Shields

300 Shields

300 Shields is the Spartan inspired mobile slot game from NextGen. You would be forgiven for spotting the parallels between it and a Hollywood blockbuster that’s based on a famous comic book.

Even though this title is getting on in years now, it is without question one of the most popular titles in this developer’s catalogue. With a fine selection of sound effects that summon up visions of war in the Mediterranean alongside a bunch of graphics that juggle images of the Acropolis and the Elysium Fields, this is one game that relies on antiquity for its theme. However when you get in amongst the spins and bonus round you’ll realise this slot packs in a whole lot of very modern wins into its reels.

What can I expect from the 300 Shields Base Game?

The 300 Shields base game plays out over 25 pay-lines that are spread across a standard five reel casino set up. You can adjust the amount of lines on which you’re betting together with the cash you’re willing to risk per line. In addition to the standard symbols on the reels there are a couple of special symbols, these are as follows:

– Warrior Wild – This special symbol can substitute for all others across the base-game grid, helping you complete the prize-paying symbol combinations where-ever possible.

– Scatter Shields – Hit three or more of these special symbols anywhere in view on the base-game grid to enter into this slot’s free spin bonus round.

How does the 300 Shields Gamble Game work?

300 Shields uses a gamble game that should be familiar to anyone who’s come within 10 metres of a mobile slot game. Any small win you hit on the reels can be gambled on the flip of a card. Guess the colour of the next ace off the pack to double your money, or if you’re feeling particularly psychic then you can guess the suit for a four times return on your cash. You can take up to four guesses giving you a chance to ramp up your win by a colossal 256 times for four correct suit predictions in a row.

What is so Special about the 300 Shields Free Spin Round?

Stop in three or more scatters anywhere in view to access the 300 Shields free spin round. This takes you onto a second set of reels where all your wins that feature warrior wilds are doubled. If you can collect two shields during these spins, you’ll receive a further five free spins and all your warrior wins are multiplied by five. Collect six shield to receive five more spins with all warrior wins multiplied by twenty five and if you can collect twelve shields you’ll receive a final five spins with all warrior wins multiplied by three hundred. You can land five more spins at any time by hitting three scatters on any single spin.

Why should I play 300 Shields?

300 Shields is a very tasty bonus slot. If you like your free spin game then this is one game you will most definitely savour and enjoy. It makes titles like Cleopatra and Piggy Riches look like they are not even touching the proverbial sides with their three and four times multiplier feature rounds. The best thing about 300 Shields is that you will often find your way into the second and third stages of the feature round where you can hit the bigger prizes, and on those rare occasions where you do manage to land the final stage of the bonus, even the smallest prize is magnified to the point where it becomes an absolute fortune.

Break Da Bank Again

Break Da Bank Again

Mobile slots games don’t come any more classic than Break Da Bank Again. This Microgaming staple has been around for years and there’s a good reason for its longevity – it’s one of the most lucrative slots you’ll ever play. With a big multiplier in both the base-game and the bonus, there’s every chance for you to hit those massive winning combinations and break the online casino’s bank time and time again. If it’s original slot excellence you’re looking for with a touch of slot machine class, then this is definitely the game for you.

What can I expect from the Break Da Bank Again base-game?

The Break Da Bank Again base-game is fast, furious and a whole load of fun. Unlike many other slots of the moment it uses a low pay-line structure with only nine pay-lines spread across the five reel set up. This means that the pay-table is nicely ramped up as it doesn’t have to accommodate a large amount of low prices, keeping this slot on the highly profitable side. In addition to the standard symbols on the reels there are two specials to help you stop in the wins:

– Wild Multiplier – Break Da Bank Again features one of the biggest wild multipliers you’ll find on any slot machine. This symbol has the power to ramp up the standard prizes of any combination by a whopping five times.

– Scatter Symbol – Stop in three or more of these safe-based symbols anywhere in view on the base-game grid and you’ll be making your way into the Break Da Bank Again bonus round with a ton of free spins under your belt.

How does the Break Da Bank Again bonus work?

The Break Da Bank Again bonus round is accessed via a scatter activation system. Three scatters wins you fifteen spins, four scatters wins twenty spins and the maximum bonus award of twenty five spins is granted if you’re lucky enough to stop in five scatters anywhere in view. You get to take these bonus spins on a special second set of reels where all your wins are paid out at a whopping five times their normal listed value.

Do the Multipliers in Break Da Bank Again work together?

One of the best things about the multipliers in Break Da Bank Again is that they can combine to offer some simply stunning prizes. Unfortunately we’re not talking about the multipliers in the base-game – hit a win with more than one wild and you’ll only receive a single 5x multiplier on your payout. However the good news is that in the bonus game where all your wins are multiplied by 5x, the wild multipliers are still in full operation. If you can stop in a win featuring a wild during this feature, it’s paid out at 25x the standard listed pay-table value.

What kind of Bank is this slot machine breaking?

There are many rumours around the casino industry concerning the story behind the theme to Break Da Bank Again. Many players believe this mobile slot game to be inspired by the famous bank robbers and safebreakers of the 20th century. We have a completely different take on this title however – it is our opinion that Break Da Bank Again is all about breaking the casino bank and cleaning out the coffers of your favourite internet operator. This is the kind of game that offers such huge winners with its five times multiplier wilds and big bonus feature action that there’s every opportunity to take all the money the casino has stashed in its vault and then some… We think this is a much more interesting and intriguing back story and hope that it inspires you to give this classic slot a few spins of your time.

What can I expect from the Agent Jane Blonde Base Game?

You can adjust your coin size, the number of coins you’re betting per line and the lines on which you’re betting to create your own bespoke wager. In addition to the standard icons there are the following two special symbols:

– Wild Multiplier – the wild multiplier not only helps you complete winning combinations on the grid, but will also double their prize paying value.

– Scatter Symbol – hit three or more of these anywhere in view on the base game grid to earn entry into this slot machine’s cool free spin round.

How does the Agent Jane Blonde Gamble Game Work?

Agent Jane Blonde features a clever gamble game. You can take any small win you receive from the reels here and risk it on the classic casino card flip gamble. If you can guess the colour of the next card off a pack then you’ll double your money, and if you’re good enough to predict its suit then you’ll gain a quadruple bounty on your stake. If you lose you return to the reels empty handed, but if you win you can gamble again in search of some big prize bounty from this quality smartphone slot.

What can I expect from the Agent Jane Blonde Feature Round?

You will need to hit three scatters anywhere in view in order to access the Agent Jane Blonde free spin round. This takes you to a second set of reels where all your wins are trebled for the duration of the bonus round. You receive fifteen free spins, which should be more than enough to land a very big bonus bounty with the chance to land in a further three or more scatters, adding an additional fifteen spins to your total. This is a generous bonus round that has the power to turn even the most dismal looking smartphone slot session into a glowing winner.

Can the Wild Multiplier still double your Wins in the Free Spin Round?

The Agent Jane Blonde wild multiplier still works in the free spin round, even though all your standard wins are trebled. This means that if you are lucky enough to make a combination in the free spin round that features the wild multiplier then you’ll be paid out a your prize at an enormous six times the listed pay-table value, giving you some of the biggest money on offer from this Microgaming mobile slot game.

Why should I play the Agent Jane Blonde Mobile Slot Game?

Agent Jane Blond is one of those slot games that offers some great wins without you having to sell your house to make the necessary stakes to get the returns you want. The ten pay-line structure means that you never have to over extend your budget and the brilliant gamble game gives you the chance to ramp up any smaller wins you hit on the reels. This means that the bonus game is the cherry on this cash rich cake with the power to pay you out some truly monster wins over the duration of your free spins. When you put together all these parts you are looking at a truly playable online slot game that never fails to disappoint.

Reel Rush

The Reel Rush mobile slot is another innovative game from Net Entertainments. Its clear fruit based theme is sure to appeal to long term fans of the genre and cracking audio never misses a beat. Don’t be fooled by its simple set up however – behind the reels of this game sits an advanced play mechanism that can set you up for some big money spins.

How does the Base Game work in Reel Rush?

Reel Rush uses a special bespoke reel set up. Rather than using conventional pay-lines, it features a ways to win system that pays you out for any adjacent consecutive combinations of similar symbols reading from left to right. Alongside this innovative mechanism it also packs a special uncovering stop space feature. This works in the following manner:

– First Stage – When you load up Reel Rush you’ll notice that several of the stop spaces on the base-game grid are blocked off and covered with an R symbol.

– Take A Spin – Spin the reels of Reel Rush and when you stop in a winning combination on the grid something unique and spectacular will happen. This slot uses a unique and innovative win mechanism like nothing you will have ever seen before.

– Open Up – Following your winning spin some of the blocked off stop spaces that are covered up with the R symbols will uncover, giving you more stop spaces.

– Increase – Every time you uncover one of the special R symbols in Reel Rush you’ll increase the number of stops and therefore the number of ways to win. Each time you hit a winner this unlocks a greater winning potential on the reels.

Does Reel Rush have any Special Symbols?

In order to help you on your winning ways there is a single special symbol in Reel Rush. This is the classic slot machine wild that will substitute where-ever possible for any other symbol on the grid. There are no bonus scatters or other types of special symbols as Reel Rush uses an innovative game-play system to activate the feature round.

How does the Reel Rush Free Spin round work?

Reel Rush packs in a spectacular and exciting free spin round. This works using a clever activation mechanism. If you can hit five consecutive wins using the special reel system in this slot’s base-game then you’ll not only be awarded with a handsome win, but you’ll also activate the free spin round here. This gives you eight free spins on the open reel set, giving you huge chances to land some awesome prizes.

Why should I play Reel Rush?

Reel Rush is a mad mobile slot that gives you a game-play that’s like no other. This machine is fast-paced, ultra generous and well named – if you can manage to get it to hit a big streak of combination wins then you’re more or less guaranteed a huge pile of cash at the end of your free spins. This is a gambler’s game – one for players who are prepared for big swings. You never quite know when this machine’s bonus round is going to hit, and then when it does the money literally rains down on you.

The Psycho Mobile slot game is based on the legendary story of Psycho, the Hitchcock thriller that sees mother-lover Norman Bates involve himself in one too many shower scenes.

This dark descent into the soul of man has created an indelible print on the cultural consciousness, and almost become a theme of its own that we’ve seen repeated across all kind of media. Now you can even spend time at the fated motel on the reels of the NextGen smartphone slot machine where the rewards run high – but do you dare take on the risks?

What can I expect from the Psycho Base Game?

Like all your favourite slots of the moment, the Psycho mobile slot game uses a familiar set up with five game reels and a twenty five pay-line structure that gives you the opportunity to line up a ton of different combinations. For an unhealthy game that verges on the side of the diseased mind and psyche, this title has a very healthy pay-table featuring some excellent wins. In addition to the standard symbols in play there are a couple of specials. These are:

– Psycho Wilds – as any slot player will tell you these super symbols can substitute for any other symbol on the grid, helping you make winning combinations. Any win that occurs with a wild is subject to a multiplier ranging between 2 and 20 times, helping you land some huge money.

– Hotel Scatters – stop in three or more of these anywhere in view to enter into the Psycho free spin round – with some of the biggest wins on offer from this slot coming if you can land five scatters.

In classic slot machine fashion you can also gamble any small win you hit on the reels of Psycho on a card flip game. Guess the colour of the next ace to double your money or if you can guess the suit you’ll win a four times return.

How does the Psycho Wilds Feature Work?

You can make quite a bit of cash from the Psycho wilds feature. At any time during a base game spin this crazy bonus can land delivering some top notch prizes. Watch as the blade wipes across the screen, stabbing stop spaces on the grid, which become wilds and adding to the winning potential of your spin. This mechanism has the power to generate some massive wins so watch out for its dark and dastardly appearance.

What’s Going On with the Psycho Free Spins?

If you like your free spin based mobile slots games then you’ll go mental for the action on offer from the Psycho bonus round without having to attend a hospital ward. Stop in three or more scatters anywhere in view and you’ll be taken to a second set of reels where you can land some big, big money. All you have to do is wait to hit those wins with the wilds and you could now earn yourself a maximum multiplier of 40x the standard pay-table value. With re-triggers on offer too, this is one bonus game that has the power to pay.

Why Should I Play Psycho?

If you’re a serious fan of mobile slots games then you’ll definitely be interested in the action put out there by psycho. This is a serious game with a curious theme. The big draw is obviously the multipliers that can ramp up your wins to some exorbitant levels in the base game and will then drive you over the top in the bonus round.

This could have been one of those productions that suffers from a lop-sided presentation, with too much action focused on the bonus round, but do you know what? NextGen have created a very playable smartphone title right here.

Gonzo’s Quest

Gonzo’s Quest

The Gonzo’s Quest Mobile Slot game takes you on a search for the legendary city of El Dorado. Join up with the Musica soldier Gonzo Pizzaro as you take on the mysterious free falling symbols in this innovative slot machine. With big money multipliers, state of the art gaming graphics and a free spin round to boot, this is a truly great slot game.

How does the Gonzo’s Quest Base-Game work?

Gonzo’s Quest uses a special system in its twenty pay-line base-game called avalanches – and as the symbols drop into place on the reels, it doesn’t have spins either, it has falls.

  • Any win you hit on the reels of Gonzo’s Quest instantly pays you out a prize. Following this the winning symbols explode leaving spaces into which the symbols above can drop. This is called an avalanche in Gonzo’s Quest, although this is more often known a cascade in the industry.
  • Each time you hit a avalanche a special multiplier is increased at the bottom of the screen. This has four levels – 1x, 2x, 3x, and 5x.
  • When the new symbols drop into place on the grid – any new winning combinations are evaluated and paid out with the special multiplier applied to the prize.
  • If you’re lucky enough to hit four or more avalanches in a row, then all the prizes are paid out at a whopping 5x their normal value, giving you a chance to hit some big money wins.

What Special Symbols are Available in Gonzo’s Quest?

There are two special symbols available in the base-game on Gonzo’s Quest.

These are as follows:

Wild symbol – This special symbol will help you out by substituting for other symbols on the grid to make winning combinations. Surprisingly this also substitutes for the free spin symbol and can help you make your way into the bonus round.
Bonus scatter – The bonus scatter on Gonzo’s Quest holds the key to the magical bonus round. This only appears on the first three reels in the game and you need to hit a combination on an active pay-line to trigger the feature.

How does the Free Fall Bonus work?

The Gonzo’s Quest free falls feature takes place on a special second set of reels. Here you’ll receive ten falls with all the multipliers trebled for the duration of the bonus round. This means that after four successive avalanches your prizes are paid out at 15x their normal value. You can also hit a re-trigger here by landing more bonus scatters on the grid and adding a further ten free spins to your count.

What’s the Story behind Gonzo’s Quest?

Gonzo’s Quest is one of the top performing slots from Scandinavian based development house, Net Entertainments. These guys have created a special range of games that push the medium to its limits – their Platinum Slots. Gonzo’s Quest is the flagship title for this brand, and when it was originally released in 2012 it made the whole internet casino world sit up to attention, bringing new levels of artwork and sound effects to the online slot medium.

Blood Suckers

Blood Suckers

Blood Suckers is a chilling mobile slot game from those devilish developers down at Net Entertainment. This rave from the grave title is chock full of undead characters that will help you bleed some big wins and spins from its reels.

It features a high payout ratio with a similarly fast and furious feature activation frequency that will have you dripping with delight as you pocket some ungodly wins. With the same high level of detail to sound and graphics as you’ll always expect from this top class producer, this is one game that will have you up all night.

Anything I should know about the Blood Suckers Reel Game?

Blood Suckers is a fairly standard slot when you look at the basic reel game. There’s a five reel casino slot set up that’s going to be bread and butter to any smartphone slot fan that boasts a twenty five pay-line set up. This is complemented by a number of special symbols to help you maximise your returns:

– Wild Symbol – these are liberally splashed all over the place giving you a chance to make up winning combinations through substitution. The wilds hold the key to grabbing the biggest prizes from the reels and free spin round.

– Bonus Symbol – grab three of these across any of the Blood Sucker’s active pay-lines and you’ll gain entry into the superb second screen game.

– Scatters Symbols – a more conventional type of feature activating special – you’re rewarded with access into the free spin round if you can nail three of these in view following any spin.

What’s the Deal with the Blood Suckers Second Screen Game?

Stop in three of the bonus symbols on any active pay-line on the Blood Suckers grid and you’ll earn entry into the clever pick a win second screen game on offer here. This gives you the chance to select one of a number of coffins in a graveyard. Hit these and find a vampire and there’s a cash reward waiting for you. Avoid the empty graves as these will end your round, paying you out your winnings. This is a fun little feature that can see you land a hot run of prizes.

How does the Blood Suckers Free Spin Round work?

Stop in three or more of the Blood Suckers scatters anywhere in view on the base game grid and you’ll gain yourself access to the free spin round. Here, in classic smartphone slot style there’s ten free spins of the reels on offer for starters – the more scatters you hit the more spins you’ll receive. This comes together with a 3x multiplier on all your prizes for the duration of the round. This gives you an excellent chance to truly sink your teeth into some of the juiciest pay-outs on offer.

Why should I play Blood Suckers?

In my opinion Net Entertainment are yet to make a bad game. They have a consist run of successful titles that promise players a fun time at the reels with plenty of prizes to book. In their marketing material for this slot they claim they’ve aimed it at the younger player, but we’d argue it’s the perfect mobile slot for anyone looking for a fast paced blend of action.

With two great bonus features that never fail to offer you some great cash and a base game that’s dripping with wild symbols, Blood Suckers will always get you out of your coffin for a few spins.
