300 Shields – NextGen


 In the Battle of Thermopylae, 300 of the boldest elite Spartan soldiers managed to stave off attacks by a 10,000 man strong Persian army for 3 days. NextGen’s fantastic 300 Shields will put you in their shoes – well, sandals – in a game where only the bravest players will survive the overwhelming odds to achieve a legendary victory.


Quite possibly the most volatile slot on this list, 300 Shields is a striking, bloody 5 reels and 25 paylines slot adventure that tests the courage and resolution of each player with its extremely high volatility. Like a true Spartan warrior, you will need to fight your way through long battles with few rewards along the way before you can reap the rewards of war. But when you do you are in for a legendary win!


Collect 3 Scattered Shields during regular play and you will enter 300 Shields’ colossal multi-level free spins bonus round featuring a god king-worthy multiplier of up to 300 times your bet amount! During the free spins round you will collect shields to move further up the Levels, earning more free spins and larger multipliers every time you level up.

Immortal Romance – Microgaming


Introduced in 2011, Microgaming’s vampire-themed Immortal Romance is still one of the most popular online slots in the world. Featuring an engaging storyline filled with intrigue, magic and undying love, this slot is not only an amazing achievement in entertainment value but is also famous for its massive payouts.


Featuring 4 different bonus games to sink your teeth into, this 243 ways to win slot may not pay out regular winning combinations too often, but it more than makes up for it with its amazing bonus opportunities.


During regular play, players may find themselves triggering the Wild Desire bonus, a hugely profitable random feature that will turn up to 5 of the reels into Wild Reels for one spin. While it normally you should not expect more than 2 Wild reels, this feature has been known to return payouts of thousands of times a player’s initial bet.


Any time a player gets 3 or more Golden Lion scatter symbols they will enter the Chamber of Spins. Here they can choose from 4 different character’s bonus games, which will be unlocked progressively:


Amber Free Spins Feature: Amber the witch will use her magic to award you with 10 free spins with 5x multipliers.


Troy Free Spins Feature: This aristocratic vampire will give you 20 free spins with a Vampire Bats feature, which will fill the reels with random multipliers.


Michael Free Spins Feature: The main love interest in this story, this 800-year-old vampire will award you 20 free spins with a rolling reels feature, in which symbols will disappear from the screen, tumbling down more symbols for bigger wins. Consecutive wins will increase the multiplier value from 2x to 5x.


Sarah Free Spins Feature: The object of Michael’s affections, Sarah will award you with 25 free spins with wandering Wilds which spread throughout the reels. Scatters will also award additional free spins.


Min/Max bet 0.30 / 6
Max win 3,645,000 coins
Free spins 25 Free Spins / Varying Multipliers
Bonus features 4 Free Spin Bonus Rounds

Dead or Alive – NetEnt


NetEnt’s Dead or Alive has been around since 2009 and has achieved legendary status for its absolutely insane free spins bonus rounds which are known to regularly pay lucky gunslingers thousands of times their bet.


At first glance, this classic 5 reel, 9-line slot does not seem particularly special. Sure, it has a fun Wild West theme, great graphics and soundtrack but it has very few paylines and it only seems to pay out small amounts every few spins.


However, once you find yourself hitting 3 scatters or more symbols anywhere on the reels, everything you thought about this game will change. During the free spin rounds, any Wild symbol that shows on the reels will become a Sticky Wild and will remain there until the end of the bonus game. If you manage to hit a Wild symbol, a Wanted poster of a legendary gunslinger, on each of the reels, you will also be awarded an additional 5 free spins.


While there are many games that feature Free Spins with Sticky Wilds, few of them are as generous with them as Dead or Alive can be. It’s very common to come out of the free spins round with over 1000x your bet, and if you managed to collect all 5 Wild Wanted Posters – one per line- you can easily generate wins of 3000-4000 times your investment or higher.


So if you are brave enough to venture on a dangerous quest into the Wild West to collect the bounty of 5 wanted legendary criminals, Dead or Alive will reward you generously for your efforts.


Min/Max bet 0.09 / 36.00
Max win £54,000
Free spins 12 Free Spins / 2x Multiplier & Sticky Wilds
Bonus features Wilds, Scatters & Free Spins

Book of Dead – Play’n GO


Exploring the world of ancient Egypt has never been more fun – or profitable – than in PlayN’ Go’s Rich Wilde and the Book of the Dead. Released in January 2016, the third slot in the Indiana Jones-like Rich Wilde franchise sees him ditch the Aztec Idols and the Pearls of India to travel to Egypt in search for the ancient Book of Dead.


As one can imagine, the titular Book of Dead is the most important symbol in this 5 reel, 10 payline adventure, acting as both a Wild and the all-important Scatter symbol. Collecting 3 of these scattered symbols anywhere on the reels will provide you with the free spins bonus round.


During this round you will receive 10 free spins during which a random symbol will be chosen to act as an expanding scatter, which will expand to cover the entire reel that it appears in. If the symbol chosen is one of the 4 highest paying symbols, you will only need 2 or more to trigger this feature, while symbols 10 to Ace will only do so when three or more show up on screen.


Regardless of the symbol chosen, this feature is sure to bring along some gigantic wins from multiple paylines, and could potentially help you trigger the slot’s epic max payout of 500,000!


Min/Max bet 0.10 / 100
Max win 500,000
Free spins 10 Free Spins / Random Expanding Scatter Symbol
Bonus features Scattered Wilds, Free Spins, Expanding Scatters
Return to Player 96.21%


Honorable Mentions:


Raging Rhino (WMS) – The highest variance slot produced by WMS, Raging Rhino offers players 4096 ways to win on every spin. However, it is their Free Spins that make this game like no other, allowing players to trigger up to 50 free spins initially and easily retrigger more of them by collecting more scatters during the free spins round. Combined with Multiplier Wilds which are multiplicative (aka a Wild with a 2x in the same payline as a Wild with 3x will combine for a 6x win), this slot will often payout up to 3000x your bet.


Gonzo’s Quest (NetEnt ) – This conquistador themed slot will take you into the jungle in a quest for El Dorado and award you mountains of Aztec gold whenever you trigger the free spins bonus rounds and the Avalanche feature brings on up to 15x multipliers!


Break Da Bank Again (Microgaming) – The name of this slot says it all. The sequel to Microgaming’s hugely popular slot gives you the chance to clean up the house with its free spins rounds featuring 25 spins with a 5x multiplier, as well as 25x multipliers for any wins with a Wild.


Medusa (NextGen) – NextGen’s Medusa provides you with enough amazing bonus features to leave you stone cold. Whether it’s the free spins round with 2x multiplier, the Super Spins with 5x multiplier, the ‘Turn to Stone’ respins with a Wild reel and 3x multiplier, or the Pegasus ‘Pick me’ feature with prizes up to 50x , there are plenty of huge wins in store for you.


Thunderstruck 2 (Microgaming) – The God of Thunder himself will provide you with an epic jackpot of up to 2,400,000 coins in this fantastic Nordic mythology themed slot.
