Microgaming Slots RTP: 2026 Immortal Romance, Mega Moolah & the Games Global Transition

Microgaming is the original online slot provider — the company that launched the first internet casino software in 1994 and developed the first online progressive jackpot (Cash Splash) in 1998. But in 2022, Microgaming exited the B2B market entirely, transferring its game portfolio and Quickfire platform to a new entity: Games Global.

This article maps the post-Microgaming RTP landscape — what happened to the Immortal Romance, Thunderstruck II, and Mega Moolah libraries under Games Global management.

RTP Configurations: The Classic Catalog

Microgaming’s classic catalog offers exceptional RTPs for their era — Immortal Romance at 96.9% and Thunderstruck II at 96.6% are among the best values in modern slots. Mega Moolah’s 88.1% base game RTP is deceptive: the 1-2% jackpot contribution rate means the true mathematics are worse than they appear for base-game-only play.

The Games Global Split

In 2022, Microgaming shut down its B2B division. Games Global acquired the Quickfire platform, the progressive jackpot network (Mega Moolah, WowPot), and distribution rights for the game catalog. Studio partners (Triple Edge, Gameburger, Slingshot) continue developing under the Games Global umbrella. The Microgaming brand lives on as a Games Global-owned trademark — but the company that started online slots no longer develops them.

Bottom Line

Microgaming is the godfather — and now a retired one. The game catalog under Games Global remains excellent for RTP (Immortal Romance 96.9%, Thunderstruck II 96.6%). Mega Moolah’s progressive math carries the brand legacy. This is a historical artifact that still plays well in 2026.
