Microgaming helped invent the online slot, and more than two decades later a handful of its titles still define the whole category. This is our editorial pick of the best Microgaming slots to play in 2026 — the games that built the studio's reputation and are still worth your spins today. For the full picture on the studio and the safest places to play, see our Microgaming casinos guide.
Mega Moolah — the record-breaking jackpot
Mega Moolah is the most famous slot Microgaming ever made, and arguably the most famous online slot period. Its cheerful African-safari theme is almost beside the point: the draw is the four-tier progressive jackpot wheel, which has triggered several world-record online payouts and a string of overnight millionaires. As a progressive, its base RTP sits lower than a standard slot (roughly the high-80s to low-90s), because a slice of every bet feeds the jackpot pool. If you play one Microgaming slot in your life, it should probably be this one.
Immortal Romance — the cult favourite
Immortal Romance is the game a lot of players name when you ask for their all-time favourite. A gothic vampire tale with a genuinely good soundtrack, it pairs a ~96% RTP with the layered Chamber of Spins free-spins feature, where four characters unlock progressively richer bonus rounds. Medium-to-high volatility keeps sessions tense. Its sequel, Immortal Romance II, revisits the same cast for players who want more of the story.
Thunderstruck II — the Norse classic
The follow-up to the original Thunderstruck, Thunderstruck II is a Norse-mythology slot built around the four-tier Great Hall of Spins. At around 96% RTP with medium volatility, it's more forgiving than Immortal Romance while still delivering a strong feature chase. It's one of the most-played Microgaming slots of all time for good reason. The modern follow-up, Thunderstruck Wild Lightning, updates the formula with wilds and multipliers.
Break da Bank Again — the classic reels
For players who like their slots simpler, Break da Bank Again is a classic bank-heist game with up to 5x multipliers in free spins and a clean, old-school feel. Around 95–96% RTP and medium volatility make it an easy, dependable pick from the back catalogue.
Licensed blockbusters: Game of Thrones & Jurassic Park
Microgaming has a strong record with licensed slots. Game of Thrones offers a choice of House free-spin modes and a ~95% RTP, while Jurassic Park brings the dinosaur theme to life with multiple free-spin modes at around 96%. Both are medium-to-high volatility and remain popular years after release.
Avalon II — the adventure quest
Avalon II is an Arthurian-themed slot built around a multi-stage adventure bonus, with one of the more generous RTPs in the catalogue (around 96–97%). It rewards players who enjoy working through a longer feature journey rather than a single free-spins round.
A note on RTP and volatility
Most standard Microgaming slots sit in the typical ~96% RTP band. Progressive jackpot titles like Mega Moolah run lower, because part of every bet funds the growing prize — a trade-off for the shot at a life-changing win. Remember that many operators can run a slot in more than one RTP configuration, so always confirm the figure in the game's own info screen. RTP and volatility are different things: RTP is the long-run payout percentage, volatility is how swingy the ride is. We break this down fully in our Microgaming guide and our online slots hub.
Where to play the best Microgaming slots
The safest place to spin these titles is a licensed casino with a strong Microgaming (now distributed via Games Global) line-up. We only recommend operators that hold a recognised licence — you'll find our current picks on the Microgaming casinos page. If you play mostly on your phone, all the titles above are built in HTML5 and run natively in the browser; see our best mobile casinos guide.
