Our Favorite Microgaming Slots
Microgaming’s slot catalog includes timeless classics, brand tie-ins, and world-record jackpot titles.
Below are some of Microgaming’s most celebrated slot titles, each representing a defining moment in the studio’s incredible legacy.
Mega Moolah
- Theme: Animals
- Format: 5x3 grid; 25 paylines; free spins and jackpot wheel
- RTP & Volatility: ~88% RTP; medium volatility
Mega Moolah is the world’s most iconic jackpot slot, known for awarding several record–breaking wins. Its gameplay is simple (25 paylines with wild multipliers and a free spins round), but the jackpot wheel is the star of the show. Players can win one of four progressive jackpots, with the Mega Jackpot regularly reaching life-changing seven- or eight-figure amounts.
Despite a low RTP (typical for jackpot slots), its legendary status and massive top prize keep it one of the most popular slots ever created.
Jurassic Park
- Theme: Dinosaurs
- Format: 5x3 grid; 243 ways to win; free spins
- RTP & Volatility: ~96% RTP; medium volatility
Jurassic Park is one of Microgaming’s most iconic branded slots, bringing the 1993 blockbuster film to life with cinematic sound design, animated dinosaurs, and several feature-rich bonus modes.
The base game is driven by 243 ways to win and the suspenseful T-Rex Alert Mode, which floods the reels with extra wilds for a limited number of spins. The free spins round is where the game truly shines: players unlock five dinosaur-themed modes, each offering a distinct modifier, such as mystery multipliers (Velociraptor), wild stacks (Brachiosaurus), or sticky-running wilds (T-Rex).
Game of Thrones
- Theme: TV, Fantasy, Dragons
- Format: 5 reels, 243 ways to win (or 15 paylines version)
- RTP & Volatility: ~95.9% RTP; medium volatility
One of Microgaming’s most successful branded titles, Game of Thrones brings Westeros to the reels, with stunning sound design and official HBO visuals. Players align with one of the Great Houses for different free spin rewards, each offering unique volatility and multiplier potential.
9 Masks of Fire
- Theme: Aztec
- Format: 5x3 grid; 20 fixed paylines; free spins
- RTP & Volatility: ~96% RTP; medium volatility
9 Masks of Fire is one of the most-played modern Microgaming-era titles. Landing 3–9 masks triggers instant win prizes, while the free spins wheel adds multipliers and solid win potential. Its clean math model, moderate volatility, and constant action make it a huge hit with both casual and seasoned slot players.
Hitman
- Theme: Action
- Format: 5 reels, 15 paylines
- RTP & Volatility: ~95.8% RTP; medium volatility
Based on the iconic video game franchise, Hitman combines stealth, tension, and precision in a slick slot experience. Its polished presentation and faithful adaptation make it a long-standing favorite among adventure fans.
Features include Contract Bonuses, Wild Expansions, and Free Spins with doubled wins.
Microgaming Slot Mechanics
Microgaming either invented or popularized several of the mechanics you'll find across online slots today. Here are the ones you'll run into most on its reels.
Progressive Jackpot Network
Microgaming's signature and its place in history: the first online progressive jackpot network, headlined by Mega Moolah and WowPot. A slice of every bet across thousands of casinos feeds shared prize pools that climb into the millions, and the jackpots trigger at random on any spin.
243 Ways to Win
Instead of fixed paylines, many Microgaming slots, such as Immortal Romance, Thunderstruck II, Jurassic Park, Game of Thrones, pay for matching symbols on adjacent reels in any position, giving you 243 ways to win on every spin.
Multi-Mode Free Spins
A Microgaming trademark — rather than one free-spins round, games like Immortal Romance and Thunderstruck II offer several. Tied to characters or unlocked in stages, each round comes with its own modifiers, so the bonus you get changes the way the game plays.
Rolling Reels
A cascading mechanic used across its catalog where winning symbols clear and new ones drop in, so a single spin can chain multiple wins in a row, often with a multiplier that climbs with each successive cascade.
Hold & Win
The lock-and-respin feature behind many of Microgaming's newer releases. Land enough cash symbols and they lock in place for a respin round, building toward instant cash prizes and jackpots.
Where to Play Microgaming Slots for Real Money
Once a Microgaming slot has won you over in demo mode, the next step is a licensed real-money casino. Look for a wide Microgaming catalog, fair terms, quick withdrawals, and a healthy jackpot section. These three are the best starting point:
| Casino | Highlights |
|---|---|
| bet365 | The deepest Microgaming selection of any US operator, including jackpot titles and Immortal Romance |
| BetMGM | A strong Microgaming shelf including Immortal Romance 2, with MGM Rewards on every spin |
| BetRivers | A well-curated Microgaming selection with iRush Rewards points and regular slot leaderboards |
For our full ranked list, see our Microgaming software page.
New players can get started with online casino free spins at leading US casinos and try these slots for real.
