Microgaming is widely credited as the oldest online casino software provider in the industry, having launched its first casino platform in 1994 from the Isle of Man. The company operates the Mega Moolah progressive jackpot network - the most famous networked jackpot in iGaming history with a record single payout of $19.4 million in 2018. At Hermes Casino, Microgaming contributes slots, table games, and progressive jackpots to the 3,200+ game library from 28 providers as of April 2026. The studio distributes content through its Apricot platform and holds licences from both the UKGC and Malta Gaming Authority. Microgaming slots at Hermes Casino contribute 100% toward the 50x wagering requirement on all bonus codes, although the low base RTP on progressive titles like Mega Moolah makes careful game selection important for bonus play.

Three Decades of Online Casino Innovation
Microgaming's history spans the entire evolution of online gambling. The company launched its first online casino software in 1994, years before competitors like NetEnt (1996), Play'n GO (2005), or Wazdan (2010) entered the market. By 2004, Microgaming had introduced the Mega Moolah progressive jackpot that would become the industry's most recognisable prize pool. The 2010s brought mobile optimisation and HTML5 conversion of the entire catalogue.
In recent years, Microgaming rebranded its content aggregation through the Apricot platform, which distributes games from both Microgaming's internal studios and partner developers. This shift means that some titles listed under the Microgaming brand at Hermes Casino are technically produced by subsidiary studios operating under the Apricot umbrella. The distinction rarely affects the player experience because the same RNG certification and regulatory oversight apply regardless of the specific studio within the network.
Regulatory Credentials
The combination of UKGC and MGA licences makes Microgaming one of the most thoroughly regulated providers available at Hermes Casino. Both authorities require independent RNG testing, transparent RTP reporting, and regular compliance audits. Although Hermes Casino operates under a Curacao licence with a Casino.Guru Safety Index of 5.2/10, Microgaming games running on the platform are certified by stricter jurisdictions. Game fairness depends on the provider's regulation, not the casino's operational licence.
Mega Moolah Progressive Jackpot
The Mega Moolah network represents Microgaming's most significant contribution to the online casino industry. No other progressive jackpot has paid out more cumulative prize money or set larger individual records.
How the Jackpot Network Functions
Mega Moolah connects thousands of online casinos, including Hermes Casino, into a shared prize pool. A small fraction of every bet placed on any Mega Moolah game across any connected casino feeds into the progressive jackpot. The prize grows continuously until one player triggers the random jackpot bonus round and wins. Four jackpot tiers operate simultaneously:
| Tier | Seed Amount | Typical Range | Trigger Frequency |
|---|---|---|---|
| Mini | $10 | $10 - $100 | Most frequent |
| Minor | $100 | $100 - $500 | Frequent |
| Major | $10,000 | $10,000 - $100,000 | Rare |
| Mega | $1,000,000 | $1M - $20M+ | Extremely rare |
The Mega jackpot seeds at $1,000,000 after each win, meaning the prize never drops below seven figures. Historical data shows the Mega tier typically triggers between $5 million and $15 million, although the 2018 record reached $19.4 million before a single player claimed it.
The RTP Trade-Off on Progressive Slots
Mega Moolah's base game RTP sits at 88.12% - significantly below the 96%+ standard for regular slots. This reduced return exists because a portion of every bet feeds the progressive jackpot pool rather than returning to players through base game wins. For every $100 wagered, the base game returns approximately $88.12 on average, with the remaining $11.88 split between the house edge and jackpot contributions.
What does that mean for your bankroll? During a $5,000 wagering session clearing a Hermes Casino bonus, Mega Moolah produces an expected loss of approximately $594 - more than three times the $176 expected loss on Wazdan's Sizzling 777 Deluxe at 96.48% RTP. The jackpot potential compensates for this cost if you trigger the Mega tier, but the probability of that happening during any single session is statistically negligible.
Warning: Avoid playing Mega Moolah with bonus funds at Hermes Casino. The 88.12% base RTP depletes your balance much faster during the 50x wagering requirement compared to standard slots with 96%+ returns. Reserve progressive jackpot play for real-money sessions where the life-changing payout potential justifies the higher house edge.
Top Microgaming Slots Beyond Progressives
Building on the flagship jackpot, Microgaming offers several non-progressive titles with competitive RTP values that work well for both entertainment and bonus wagering at Hermes Casino.
Immortal Romance - Vampire Theme at 96.86%
Immortal Romance is a vampire-themed video slot with 96.86% RTP - the highest return in the Microgaming catalogue at Hermes Casino. The game features four different free spins modes that unlock progressively as you trigger the bonus round multiple times within a session. Each mode offers different mechanics:
- Amber mode - 10 free spins with a 5x multiplier on all wins, unlocked on the 1st trigger
- Troy mode - 15 free spins with Vampire Bats that transform symbols into 2x or 3x wilds, unlocked on the 5th trigger
- Michael mode - 20 free spins with Rolling Reels and increasing multipliers up to 5x, unlocked on the 10th trigger
- Sarah mode - 25 free spins with Wild Vine that randomly transforms symbols, unlocked on the 15th trigger
The progressive unlock system rewards extended play sessions because later modes typically produce larger payouts. This design makes Immortal Romance particularly engaging for longer sessions, although reaching the Sarah mode requires significant session length due to the 15-trigger threshold.
Thunderstruck II - Norse Mythology
Thunderstruck II uses Norse mythology featuring Thor, Odin, Loki, and Valkyrie across a 5-reel, 243-ways-to-win format. RTP reaches 96.65% with medium-to-high volatility. The Great Hall of Spins bonus operates similarly to Immortal Romance's progressive unlock - four different free spins features become available as you trigger the bonus repeatedly.
The 243-ways mechanic replaces traditional paylines with a system where matching symbols on adjacent reels from left to right create winning combinations regardless of their exact position. This format produces more frequent small wins than fixed-payline games, which helps sustain your balance during extended sessions.
Break da Bank Again and Avalon II
Break da Bank Again is a heist-themed slot with 96.42% RTP and a free spins round featuring 5x multipliers on all wins. The straightforward design and above-average return rate make it a practical choice for bonus wagering alongside Immortal Romance. The "Again" sequel improves on the original Break da Bank with enhanced graphics and a higher maximum win potential.
Avalon II takes the Arthurian legend theme further than the original Avalon with a quest-based bonus system where players progress through 8 different bonus stages across multiple sessions. RTP is approximately 96.01% with medium volatility. The multi-session progression mechanic is unusual among slot games and appeals to players who enjoy storyline-driven gameplay.
Microgaming and Hermes Casino Bonuses
All Microgaming titles at Hermes Casino contribute 100% toward bonus wagering under standard conditions. However, choosing the right Microgaming slot for bonus play makes a significant mathematical difference because of the wide RTP range across the catalogue.
Best Microgaming Titles for Bonus Clearing
For the 50x wagering requirement on the welcome package or no deposit bonus, rank Microgaming slots by RTP:
| Rank | Game | RTP | Expected Loss per $5,000 Wagered | Recommended For |
|---|---|---|---|---|
| 1 | Immortal Romance | 96.86% | $157 | Entertainment + wagering |
| 2 | Thunderstruck II | 96.65% | $167.50 | Ways-to-win fans |
| 3 | Break da Bank Again | 96.42% | $179 | Straightforward wagering |
| 4 | Avalon II | 96.01% | $199.50 | Storyline seekers |
| 5 | Mega Moolah | 88.12% | $594 | Real money only |
Immortal Romance at 96.86% produces the lowest expected loss among Microgaming titles, making it the optimal choice for bonus clearing. The progressive unlock system also keeps sessions engaging during the often monotonous wagering grind. Betsoft's A Night in Paris at 97.33% and Wazdan's Sizzling 777 Deluxe at 96.48% offer alternatives from other providers.
Claiming Bonuses for Microgaming Play
Register at Hermes Casino and claim the $10 no deposit bonus with codes EXT10, MANI10, or GOLD10 through 24/7 live chat. The free bonus works on all Microgaming slots including Immortal Romance and Thunderstruck II. Maximum cashout is capped at $30 with 50x wagering on slots only. The welcome package with codes HERMESGOLD through HERMESUPREME offers up to $12,000 plus 240 free spins across six deposits. The VIP programme adds cashback up to 25% on net losses.
Tip: If you want to experience Mega Moolah's jackpot chase without the RTP penalty during bonus play, clear your wagering on Immortal Romance first. Once the bonus is complete and winnings are withdrawn, switch to Mega Moolah with real-money funds where the progressive potential adds genuine value beyond base game returns.

The jackpot bonus round triggers randomly after any paid spin regardless of bet size.
Which Microgaming Slot Has the Highest RTP?

Thunderstruck II follows at 96.65% and Break da Bank Again at 96.42%. Avoid Mega Moolah (88.12%) for bonus wagering due to the low base return.
Should You Play Mega Moolah With Bonus Funds?
Playing Mega Moolah with bonus funds is not recommended because the 88.12% base RTP depletes your balance approximately three times faster than standard 96% slots during the 50x wagering requirement.

Do Microgaming Games Count Toward Bonus Wagering?
All Microgaming slots at Hermes Casino contribute 100% toward the 50x wagering requirement on the welcome package and no deposit bonus.
