What Are the Best Mr Green Slots Online?

GamblersPro.com put together this list of the best Mr Green Casino slots to help players quickly decide what games to play. Those familiar with Mr Green Casino know it has hundreds of epic slots to choose from, but these are the best of the bunch.

Power of Thor Megaways

We’ve covered lots of Megaways slot games on this site, and that’s because they’re awesome. This one is based on Norse gods, particularly Thor, and as always with Pragmatic Play, the theme and graphics are world-class.

This game has six reels, 117,649 ways to win, and an RTP of 96.5%. Penny players can bet $/£0.20, and those with more cash can wager $/£100 per spin. It’s a highly volatile game, so keep that in mind as you play.

This game has tumbling reels: with each win, the symbols disappear and new ones fall in from above. This keeps happening until no new wins are created. When Thor’s hammer lands, symbols below it turn into wilds, essentially turning the reel into a wild reel. This continues even when the tumbling reels are in play.

The free spins feature is the main one to look out for. Players need to land scatters that spell out THOR to trigger it. The round starts with 10 spins, with each extra scatter adding four more, up to 30 maximum. During the free spins, a progressive multiplier is in play. It starts at 1x and grows by 1x on every tumble.

This is one of the best Megaways slots at Mr Green. You can often play Megaways games with some of the promos offered with Mr Green promo codes.

Hall of Gods

Hall of Gods is one of the most-played progressive jackpot slots of all time. It has a Norse gods theme and is powered by NetEnt. Loki, Odin, Idun, and Freya fill the reels, along with Norse jewellery and weapons like axes and hammers.

The serpent symbol is the wild, and it can expand to cover every reel it lands on. It can fill the middle three reels to create some epic winning combinations. Odin’s raven is the scatter. Three or more of these trigger the free spins feature, awarding 10, 15, or 20 spins for three, four, or five scatters respectively. All free spins benefit from a multiplier that triples wins.

The picking feature is triggered by landing three of Thor’s hammers on the reels. Players use the hammer to break shields and reveal cash prizes behind them. Landing the progressive jackpot turns one lucky player into an instant millionaire.

Hall of Gods is one of the best Mr Green slots. A massive progressive jackpot could be yours on any spin.

Immortal Romance

Immortal Romance is Microgaming’s gothic vampire slot and one of the highest-RTP games in the Mr Green catalogue at 96.86%. It runs on a 5×3 grid with 243 ways to win and has built a loyal following over more than a decade for one reason above all others: the Chamber of Spins bonus system.

The Chamber unlocks four progressively powerful free spins modes tied to the game’s four central characters (Amber, Troy, Helen, and Michael), each one revealing more features as the bonus is triggered more times. Amber’s room opens first with 10 free spins and a 5x win multiplier. Troy’s follows with rolling reels and an escalating multiplier. Helen’s delivers 15 spins with a Wild Desire feature that randomly turns entire reels wild. Michael’s room, the most coveted, gives 25 free spins with rolling reels, a 6x multiplier ceiling, and Wild Desire combined.

Each mode must be unlocked by accumulating bonus triggers over multiple sessions, which gives Immortal Romance a sense of progression that most slots can’t match. With a 12,150x max win and one of the best RTPs in the Microgaming catalogue, it’s a strong all-round pick at Mr Green for players who want depth alongside solid returns.

Irish Riches Megaways

Irish Riches is one of the most-loved Blueprint Gaming slots. As with most Irish slots, it’s a caricature of Ireland with pots of gold, rainbows, leprechauns, and gemstones on the reels.

This slot has six reels and 117,649 ways to win. It has an RTP of 95.93% and is a low volatility game with plenty of small, frequent wins, making it an ideal slot for beating wagering requirements.

The free spins feature is triggered by four scatters landing anywhere on the reels, and the round opens with 12 free spins. Every additional scatter adds four extra spins for a maximum of 22.

What most players focus on is the progressive jackpot. Jackpot King overlays can appear on the reels randomly, and once 15 are collected, the Wheel King Bonus opens. Three jackpots are available, and at the time of writing the biggest one is well over £15 million.

Divine Fortune

Divine Fortune is NetEnt’s Greek mythology progressive jackpot slot and a natural companion to Hall of Gods on this list, though the two games feel completely different. Where Hall of Gods leans into the epic Norse picking bonus, Divine Fortune is built around a medium-volatility base game with frequent wins and three progressive jackpot tiers (Minor, Major, and Mega) sitting above it all.

It runs on a 5×3 grid with 20 paylines and an RTP of 96.59%. The main features are Falling Wild Respins (wilds that drop one position per respin until they fall off the reel, triggering free respins with each drop) and a Wild on Wild mechanic where a wild landing on an existing wild expands to fill the entire reel. The free spins bonus awards five spins with the expanded wild mechanic active throughout, and the Jackpot Bonus can be triggered randomly on any spin to award one of the three jackpot prizes.

Medium volatility makes Divine Fortune one of the more sustainable jackpot slots at Mr Green. The win frequency is high enough to keep sessions comfortable while the Mega jackpot, which has paid out millions historically, sits in the background on every spin.

Book of Dead

Book of Dead is Play’n GO’s flagship slot and arguably the most-played video slot at any UK or European casino, Mr Green included. It follows explorer Rich Wilde into an Egyptian tomb, with symbols featuring Tutankhamun, Anubis, the Phoenix, and gilded book icons on a 5×3 grid with 10 paylines set against a richly detailed funerary backdrop.

High volatility and a 96.21% RTP deliver less frequent wins but with serious payout potential. The maximum win sits at 5,000x the stake, typically unlocked during bonus play. The key mechanic is the Free Spins feature, triggered by landing three or more Book of Dead scatter symbols anywhere on the reels. The round awards 10 free spins during which a random symbol is chosen as the Expanding Symbol. When it lands and contributes to a win, it expands to cover the entire reel, significantly boosting win potential. The feature can retrigger on three more scatters.

Book of Dead is the UK template for the entire “Book of” genre that’s dominated online slots for the past decade. A genuine staple of every major European casino lobby and a core pick for anyone who hasn’t yet tried the Rich Wilde series.

Starburst

Starburst by NetEnt is the most-played online slot of all time and a natural fit for Mr Green given the casino’s Swedish founding heritage shares a bloodline with NetEnt itself. The 5×3 grid with 10 paylines uses a Win Both Ways mechanic where combinations pay both left-to-right and right-to-left, effectively doubling winning chances on every spin. Space-themed jewel symbols, bars, and a lucky red seven fill the reels against a cosmic backdrop.

Low volatility and a 96.09% RTP make Starburst one of the most approachable slots at Mr Green. The Starburst Wild is the central feature, landing on reels 2, 3, and 4 only. When it appears, it expands to cover the entire reel and triggers a re-spin. If another wild lands during the re-spin, it also expands and triggers another, up to a maximum of three consecutive re-spins. The max win of 500x the stake keeps ceilings modest, but the frequent-win hit-rate and the re-spin mechanic make Starburst a perennial favourite for bankroll-conscious sessions and a useful contrast to the higher-volatility jackpot slots elsewhere on this list.

Arcade Bomb

For players who like old-school fruit machines with a modern twist, this slot will be right up their street. It’s set in the stars and features fruit, bells, 7s, bars, and other classic symbols on the reels. In some ways, it will remind players of the Starburst slot.

Arcade Bomb is powered by Red Tiger Gaming. It has an RTP of 96.15% and is a low volatility game. Expect plenty of small wins to keep bankrolls ticking over.

The standout feature is Locked Reel Bombs. On each spin, bomb symbols drop onto the reels and lock in their positions. Each bomb has a number attached, and after that many spins it explodes. When it does, all the symbols in its blast pattern turn into the same symbol, often creating substantial single-spin payouts.

With a maximum win of 1,000x, this simple, fast-paced game is one of the best Mr Green slots. The list includes games for every type of player, and this one appeals most to those who like classic fruit machines.

Blood Suckers

Blood Suckers by NetEnt sits at the very top of the RTP charts with 98.00%, one of the highest of any slot in the Mr Green library and a figure that makes it mandatory reading for any player who cares about long-term return. It’s a vampire-themed 5×3 slot with 25 paylines and medium-low volatility, which means the high RTP is backed by regular base-game wins rather than relying on rare bonus hits to deliver it.

The Vampire Slaying bonus is the main feature. Triggered by landing three or more coffin scatters, it takes players to a pick-and-click screen where coffins are opened to reveal cash prizes. The more coffins cleared without hitting a vampire, the more cash collected. A separate free spins bonus awards 10 spins with a 3x multiplier applied to all wins throughout the round.

Blood Suckers won’t produce the session-defining jackpot moments of Hall of Gods or the unlockable depth of Immortal Romance, but that’s not the point. For making a balance work harder over a longer session, or simply for clearing a bonus efficiently, the 98% RTP makes this one of the most player-friendly games on the entire Mr Green platform.
