Sweepstakes Alternatives

Microgaming's slots reached the sweepstakes world in 2025, so you can play classics like Immortal Romance and Thunderstruck even if you're not in a state that offers real-money casinos. One thing to note: at sweepstakes casinos, Microgaming's games are listed under its M2Play label rather than the Microgaming name, but they're the same titles. These approved sites carry them:

About Microgaming

Microgaming is one of the longest-established names in online casino gaming, with a history stretching back to the earliest days of the industry. Its software, progressive jackpots and extensive games catalog have helped shape how online casino content has developed over the past three decades.

History

Founded in 1994 on the Isle of Man, Microgaming is widely credited with developing the first online casino software that same year. It continued to expand its technology over the following decades, including moving into mobile gaming in 2004 and launching the Quickfire platform in 2015.

Quickfire allowed independent studios to distribute their games to online casinos through a single integration, significantly expanding Microgaming's available catalog and operator reach.

The company also established one of the industry's best-known progressive jackpot networks. Mega Moolah became its flagship jackpot slot, while games such as Immortal Romance and Thunderstruck II became long-running favorites. Microgaming also produced a number of branded slots based on major entertainment franchises, including Jurassic Park and Game of Thrones.

In 2022, Games Global acquired Microgaming's games portfolio, Quickfire platform and distribution network. As a result, Microgaming's established game catalog is now owned and distributed by Games Global, while Microgaming has shifted its focus toward platform and systems technology. In regulated US markets, former Microgaming content is therefore distributed to operators through Games Global.

Awards & Reputation

Microgaming is also an industry leader in corporate responsibility — it co-founded the eCOGRA testing body and backs charity through its PlayItForward program. Its independent years produced a long run of industry awards, including:

• Platform of the Year at the 2020 EGR B2B Awards
• Innovation in Slot Provision at the 2019 EGR B2B Awards
• iGaming Software Supplier of the Year at the 2018 International Gaming Awards
• Mobile Product of the Year at the 2017 International Gaming Awards
• Digital Product of the Year ("Quickfire") at the 2016 Global Gaming Awards
• Digital Product of the Year ("Jurassic Park") at the 2015 Global Gaming Awards
• Digital Product of the Year at the 2014 Global Gaming Awards

Types of Microgaming Games

Microgaming's catalog spans nearly every genre, but it breaks down into a few clear types with a couple of mechanics that run through all of them.

Slots

Slots are Microgaming's foundation, from timeless classics to blockbuster brand tie-ins. Here are three of the top Microgaming games as rated by Gambling.com members:

• Immortal Romance – Best known for its Chamber of Spins, which unlocks four character bonuses as you progress: Amber offers 10 spins at 5x, Troy adds Vampire Bat multipliers up to 6x, Michael brings Rolling Reels, and Sarah awards 25 spins with expanding Wild Vines. 
• Thunderstruck II – Its Great Hall of Spins progressively unlocks four bonuses themed around Valkyrie, Loki, Odin and Thor, including 5x wins, Wild Magic, Wild Ravens and Rolling Reels. The separate Wildstorm feature can also turn up to five reels fully wild. 
• Jurassic Park – – Uses 243 ways to win alongside several dinosaur-driven features. T-Rex Alert can add extra wilds to the reels, while the free-spins round offers five different dinosaur modes, including mystery multipliers, stacked wilds and running wilds.

Progressive Jackpot Slots

Microgaming became particularly well known for its progressive jackpots, where qualifying bets across multiple casinos contribute to the same prize pool. Mega Moolah uses a four-tier jackpot wheel — Mini, Minor, Major and Mega — while the WowPot network links a newer group of slots to shared progressive prizes that can grow independently of the base-game wins.

Table Games 

Microgaming's catalog also covers RNG blackjack, roulette, baccarat and poker-style games. That includes classic and multi-hand blackjack formats, European and American roulette, punto banco baccarat, plus video poker variants such as Jacks or Better and other draw-poker formats.

Responsible Gambling on Microgaming Casinos

Microgaming operates under some of the most respected licenses in the industry, and its games reach US players only through casinos regulated by state authorities.

Every title is independently tested for fair RNG performance and accurate RTPs by eCOGRA for full transparency.

The company also backs responsible gambling through partners like BeGambleAware, Gambling Therapy, and Ygam, and its licensed casino partners provide player tools including deposit limits, self-exclusion, and time reminders. With a jackpot slot like Mega Moolah running a deliberately low base RTP, setting a budget before you play is well worth it.
