The Pioneer of Online Slots
Microgaming holds a unique place in the online gambling world: they are widely credited with developing the first true online casino software in 1994. Over three decades later, their slot portfolio remains one of the most extensive in the industry, with hundreds of titles covering every theme and mechanic imaginable.
For players focused on RTP, Microgaming's long track record and regulatory history make them one of the most transparent and trustworthy providers when it comes to published payout data.
Microgaming's RTP Philosophy
Microgaming games are tested and certified by independent auditors, including eCOGRA — an organization that Microgaming itself helped found. This means RTP figures attached to their games have undergone rigorous third-party verification.
- Typical RTP Range: 94% – 98%
- Notable High-RTP Title: Mega Moolah (jackpot game, base RTP ~88% — offset by jackpot contributions)
- Notable Standard-RTP Titles: Thunderstruck II (~96.65%), Immortal Romance (~96.86%), Avalon II (~97.11%)
Progressive Jackpots and RTP: An Important Caveat
Microgaming is famous for its Mega Moolah progressive jackpot network, which has produced some of the largest online slot jackpot payouts ever recorded. However, players should understand how jackpot games affect RTP:
- A portion of every spin's wager contributes to the jackpot pool.
- This contribution lowers the base game's RTP.
- The "full" RTP is only realized by whoever hits the jackpot.
- For most players on most sessions, the effective RTP of a progressive jackpot slot is lower than the stated figure.
This is not unique to Microgaming — it applies to all progressive jackpot slots across all providers. Always read the fine print on jackpot game RTPs.

Recent Developments: Microgaming's Evolving Strategy
In recent years, Microgaming has shifted its development model, partnering with independent game studios to publish their content under the Microgaming platform. Studios like Triple Edge Studios and All41 Studios now release games through Microgaming's distribution network. This has led to a broader range of styles and mechanics while maintaining the provider's certification standards.
Is Microgaming Still Relevant in 2025?
With newer providers like PG Soft capturing attention through flashy visuals and mobile-first design, some wonder if Microgaming is still a top choice. The answer depends on what you value:
- For RTP transparency and trust: Microgaming remains a gold standard.
- For classic, narrative-driven gameplay: Titles like Immortal Romance and Thunderstruck II are timeless.
- For cutting-edge mobile graphics: Newer providers may have an edge.
Microgaming's decades of regulatory compliance and certified RTP data make them a reliable baseline for any RTP-informed player's game selection.
