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.

Merlin’s Magic Respins

Merlin’s Magic Respins

Merlin’s Magic Respins is another addition to the Merlin range of mobile slots games from NextGen. This superb smartphone title has a clever mechanism in the base-game that gives you the ability to land in respins at any given moment together with a free spin feature that can pump out the big prizes.

With state of the art graphics and out of this world sound effects, this slot has everything you could want for an absolutely supernatural playing experience.

What can I expect from the Merlin’s Magic Respins Base Game?

The base game on offer from Merlin’s Magic Respins plays out over a standard casino five reel set up that features four stops on each reel. Here you have fifty pay-lines on which to make your bets, with the option to make a super-bet, which we will come to later in the review. There are two special symbols to help you hit those wins:

– Stacked Wild Symbols – these appear on the middle three reels of the game and will help you out by substituting where-ever possible to help you make winning combinations.

– Potion Scatter Symbols – in the traditional smartphone slot style, hit three of these anywhere in view on the base game grid to transport yourself into the game’s free spin round.

How does the Merlin’s Magic Respins Mechanism work?

Merlin’s Magic Respins unsurprisingly features a very lucrative re-spin mechanism. Whenever you hit a full stacked of wild symbols anywhere on the base game grid this will trigger out a straight re-spin with the wild symbols locked in place, giving you a chance to land a good number of multiple combinations across the reels. You can control the number of respins with the super-bet function. The more money you’re willing to spend per spin, the more re-spins you can receive up to a maximum of five.

During these wild respins the wild symbol will also appear on the first and last reels of the grid, giving you extra chances to earn big prizes.

How can I gain extra Wild Symbols on the Reels of Merlin’s Magic Respins?

During the base game on this mobile slots game, Merlin can summon up the forces of magic and summon a number of wild symbols onto the reels. This happens when all the symbols have fallen into place on your existing spin, ramping up the winning potential of the grid. If you’re very lucky this mechanism will add a complete stack of wilds to the reels triggering the respin system, which could spark an avalanche of wins.

What can I expect from the Merlin’s Magic Respins Feature Round?

With all the action in the base game you’d forgive Merlin’s Magic Respins for not featuring a bonus, but guess what? This clever smartphone slot gives you a little bit more action in the form of a free spin round. This is activated when you hit the three pink potion scatters anywhere in view on the base-game, taking you to a second set of reels where Merlin will still be in full effect to magic up the wilds and you’ll receive a seven free spins.

Why should I play Merlin’s Magic Respins?

Merlin’s Magic Respins is a mobile slots game that is like no other. This cool smartphone title gives you a ton of chances to win it big in the base game with the respin function and you can control the amount of excitement this gives you with the cool super-bet system. With Merlin popping up to enchant the reels with extra wilds and the possibility of hitting even more prizes in the free spin feature round, this title will cast a spell on your and hopefully conjure up a whole load of sparkling wins into your casino bankroll.

Evel Knievel

When it comes to insane motorcycling stunts, few have pulled out the tricks like Evel Knievel.  Now you can catch the spirit of this true American hero on the reels of the Evel Knievel Mobile Slot Game, a big money slot machine that come packed with a huge slice of free spin action together stacked wilds and a special bonus within a bonus.

What can I expect from the Evel Knievel Base-Game?

The Evel Knievel base-game uses a large fifty line grid. This has an additional row of stop spaces giving you twenty positions into which you can land winning combinations. To help you hit those wins there are a couple of special symbols that feature on all reels. These are as follows:

– Wild – The Evel Knievel wild symbol can substitute for any other symbol on the base-game grid, helping you complete those all important winning combinations.

– Scatter – The Evel Knievel signature scatter symbol holds the key to entering this slot machine’s first level free spin round, where the action really hots up.

How does the Evel Knievel free spin round work?

The first level free spin round on Evel Knievel is activated when you hit three of the signature scatters anywhere on the base-game grid. This takes you to a second set of reels where you receive fifteen free spins. Here you’ll find there’s a ton of stacked wilds added to the second, third, fourth and fifth reels to help you hit those winning combinations in a big, big way. Rather than offering you a re-trigger here, if you can hit a further three Evel Knievel bonus symbols you’ll access the Big Stunt bonus.

What is the Big Stunt Bonus?

Did you know that Evel Knievel has a free spin round within its free spin round? If you can hit three of the special Evel Knievel scatters anywhere in view during your free spins, you’ll activate a special Big Stunt bonus. This is what’s known as a locked free spins round where the reels just keep on spinning until you hit one of the special caped Evel Knievel scatters on the middle reel. If your luck has come in, this free spin round can go on for a long time paying you out a huge amount of prizes, and even a short burst of spins can be incredibly lucrative. Once you locked free spins are finished, you’re returned to the normal free spin reels where you get to play out the remainder of your spins.

Why should I play Evel Knievel?

Even though Evel Knievel has a fairly high spin cost, this is a game that offers some fantastic rewards. The general wins are all at a good level in the base-game, but it’s when you manage to get into the free spin round that this mobile slot game switches up a gear. The stacked wilds have the ability to turn any spin on the second set of reels into an absolute pay-out frenzy and the Big Stunt bonus round can keep pumping out the prizes for some truly astounding feature jackpots. This is a quality game that’s full of the best sound effects and graphics, backed up with a huge pot full of money that adds up to one of the best big mobile slot experiences you’ll find online.

Alaskan Fishing

Alaskan Fishing

The Alaskan Fishing mobile slot game gives you the chance to get out into the wild casino outdoors and hunt down some big game quarry in the form of some whopping wins. This title features some of the best mobile slots game artwork that you’ll find anywhere with a host of rich, hand-drawn symbols.

What can I expect from the Alaskan Fishing base game?

Alaskan Fishing is another slot from Microgaming that uses their special 243 ways to win system, paying you out for any combination of symbols on the grid. Like another one of their slots featured on our site – The Twisted Circus – this game still manages to give you a very exciting pay-table in line with this large pay out system. In addition to the standard symbols there are a number of specials available from this mobile slots game:
– Stacked Wilds – This is the signature Alaskan Fishing symbol. It acts as the game’s wilds, helping you complete winning combinations where-ever possible. The symbol stacks will make sure those wins appear all over the grid.

– Fly Fishing – This special fishing reel scatter only appears on the first and last reels of the grid. You will need to hit two of these to gain access to the brilliant Fly Fishing second screen bonus game on Alaskan Fishing.

– Tackle Box – The free spin feature on offer from Alaskan Fishing requires you to hit three of the tackle box scatters to activate its treasures. These can be hit on any reel, anywhere in view.

How does the Fly Fishing bonus game work?

You can get into the outdoors spirit with the Alaskan Fishing second screen bonus game. This takes you to a traditional fly fishing contest where you get to prove your skill with the rod, by seeing if you can land a prize pike out of the pool. Choose your fishing spots carefully and hook in your catch – each fish you hit will land you a tasty cash reward and if you can bag a bundle of big bonus bass then you’ll net yourself a huge amount of cash. There’s no secret to playing this game, just hit the water and you’re bound to land a good prize.

What can I expect from the Alaskan Fishing free spins?

Like any quality slot machine, the free spin round on Alaskan Fishing is one of the most lucrative opportunities in the game. When you hit the three scatters necessary to take you into this bonus, you’ll float off to a special second set of reels where you can hook yourself the biggest prizes on offer from this feature where all your prizes are trebled for the duration of your fifteen free spins.

Why should I play Alaskan Fishing?

Alaskan Fishing is one of those slot games that simply seems to manage to deliver on its promises. Whilst many slots out there have plenty of winning potential, few actually have the ability to turn this into cold, hard cash. Whilst this game obviously doesn’t guarantee that you’ll walk away a winner, it will always give you a good, fun ride where you’ll mix a good amount of hot streaks with some colder moments. All you have to do is judge when to take your haul of prizes home with you and you’ll be an expert fisherman.

Steam Tower

Steam Tower

The superb Net Entertainment Steamtower mobile slot game comes with a wonderful music-hall soundtrack that could almost be emanating from an old school steam organ, together with industrial graphics that set the scene perfectly for all the big money action on offer if you have what it takes to climb the Steamtower to the top.

So what’s going on in the Steamtower Base Game?

If you like your slots with a lot of oomph in the base game then Steamtower has the power to satisfy. This twenty pay-line game uses the standard five reel set up that has existed in the industry ever since it was first used on the poker card reel machines of the Wild West. In order to help you hit your wins there are a couple of special symbols available. These are as follows:
Single Wilds – these hook symbols can substitute for any other symbol on the grid, helping you complete those all-important winning combinations.

Stacked Wilds – stop in a stacked wild right the way across a single reel to gain access into this mobile slot games free spin round where you can earn the biggest prizes on offer.

Climb all the way to the top of the tower and you’ll gain a 6,000 coin prize for defeating the dragon and a whole bunch of spins at the games max multiplier of 7x.

Jack And The Beanstalk

Jack And The Beanstalk

If you want a mobile slot machine golden goose, then why not try Jack and the Beanstalk? This cool Net Entertainment game packs in some awesome 3D styled graphics with an exciting soundtrack to create one of the most enjoyable gaming experiences around… And that’s before you look at the innovative reel respin system and the extra wilds free spin round that are packed full of fairy- tale riches.

How does the Jack and the Beanstalk Reel System work?

Jack and the Beanstalk uses a simple twenty pay-line, five reel base-game with a little bit of a difference. In addition to the standard slot machine mechanism there’s a very ingenious Wandering Wild respin feature that works with the wild symbol in Jack and the Beanstalk. It works in the following manner:

-Stop in a Wild – When you hit a wild anywhere on the base-game grid, your normal winning combinations are evaluated and any prizes you’ve received are paid out in the normal manner.

– The Wild Shifts – A single reel to the left and locks in place. The remaining reels of the Jack and the Beanstalk slot machine then re-spin, with new symbols dropping into place on the grid.

– New Wins – Are then evaluated on the grid and any prizes are paid out. If the wild symbol has reached the left-most reel, then it will drop off the grid and you’re given one final respin In addition to this any wins you hit with the special Jack and the Beanstalk signature wild are paid out at three times their normal value.

What triggers the Free Spin Round?

The free spin round on Jack and the Beanstalk is simply triggered with a special treasure chest scatter symbol. Hit three of these anywhere in view to enter the free spin round with ten spins under your belt. If you can manage to hit three more of these special symbols during the feature round then you’ll add a further five spins to your total.

How do the Free Spin Wilds work?

The Jack and the Beanstalk free spin round works on a special second set of reels. This has the same number of pay-lines as the normal reel set and the Wandering Wild system is still in full effect. However players can land in special key symbols to unlock advanced wild types. These include:

– Double Stacked Money Bags – Collect three golden key symbols from the reels of the free spin round and all the wilds on the grid will turn into double stacked wilds for the duration of the rest of your free spins.

– Triple Stacked Hens – Collect a further three golden key symbols in the free spin round and all the wilds will turn into triple stacked golden hens for the duration of the bonus

– Golden Expanding Harps – When you collect a final three golden key symbols off the free spin reels all the wilds turn into expanding golden harps. Simply stop in a wild anywhere in view and this will expand to fill the entire reel.

How big can the Bonus Wins get on this Slot?

Just as a huge beanstalk grew from little beans in the Jack and the Beanstalk fairy tale, you can hit some truly massive wins in the free spin round here. The wandering wild activation system ensures that your free spins get stretched beyond the ten standard spins that come with the bonus and you’re more or less guaranteed to get one or two of the special wild types to help you on your winning ways. This means that the bonus wins here tend to encroach on the larger side of the casino winnings – it’s not uncommon to see players walk away with prizes equal to well over five hundred or even a thousand times their basic playing stake.
