One studio, one confirmed title - but it's the best RTP on the site
Microgaming is the fourth of five providers we named when we counted the Jack.com lobby on 28 July 2026 - 10,761 titles that day, split into 9,926 slots, 808 live tables and 27 mini games, all still live under the new name after Jackbit's May 2026 rebrand. We didn't try to log the studio's full catalogue on the platform. What we did confirm, by name and RTP, is one title: Immortal Romance.
| Title | Provider | RTP |
|---|---|---|
| Immortal Romance | Microgaming | 96.86% |
| Big Bass Bonanza | Pragmatic Play | 96.71% |
| Legacy of Dead | Play'n GO | 96.58% |
| Wanted Dead or a Wild | Hacksaw Gaming | 96.38% |
96.86% isn't just Microgaming's number - it's the single highest RTP we confirmed anywhere in the lobby that day, ahead of every Pragmatic Play, Play'n GO and Hacksaw Gaming title we logged. For a studio with exactly one title we could verify here, that's a stronger opening card than the confirmed-title count alone suggests.
What Immortal Romance actually is
It's a long-running Microgaming release built around a vampire-romance theme, best known industry-wide for its Chamber of Spins - four separate free-spin features (Wild Desire, Chamber of Spins, Vampire Bat and Wild Lions) that unlock progressively the more you trigger the bonus, each with a different multiplier ceiling and mechanic. That structure is public knowledge about the title generally, not a claim about how it behaves specifically inside this operator's build - we haven't run a real-money session on it here.
Why we're not claiming more than one title
AskGamblers' older listing for this operator cites "70+ providers", a figure broad enough that it likely includes more Microgaming content than the single title we could tie to a name and RTP. We're treating that as a secondary, pre-rebrand source rather than folding it into this page as fact - a lobby count and a marketing provider list aren't the same kind of evidence, and we'd rather show one verified title than round a vague claim up into several.
Microgaming is confirmed live at Jack.com (formerly Jackbit). The one title we could verify by name is Immortal Romance at 96.86% RTP - the highest confirmed RTP anywhere in the 28 July 2026 lobby count.
Check today's lobbyMicrogaming against the other three confirmed studios
Pragmatic Play and Play'n GO carry the deepest confirmed rosters here - five and three named titles respectively - while Hacksaw Gaming sits in the same one-title position as Microgaming. The difference is what that single title is worth: Hacksaw's confirmed slot runs 96.38%, half a point below Microgaming's 96.86%. Neither figure says anything about how many more titles either studio actually has live here - only about what we personally verified.
The rebrand doesn't change any of this. Whatever integration deal put Microgaming content in the Jackbit lobby carried straight over to Jack.com in May 2026 - a name change on the front end, not a renegotiation of studio contracts behind it.
Our take
Written by Rhona Sutcliffe. One confirmed title is a thin sample to profile a studio on, and we're saying so directly rather than padding it out. What we can stand behind: Immortal Romance is a legitimate, well-known Microgaming release, and at 96.86% it's the best-paying confirmed slot in this entire lobby audit. If a deeper Microgaming catalogue is what you're after, check the live site directly - our count is a snapshot from one date, not a running total. New here first? The welcome bonus covers the current sign-up spins, which land on Hot Chilli Bells, not on Immortal Romance.
