Microgaming in Ontario: Microgaming is one of the oldest names in online casino games and the studio behind some of the biggest progressive jackpots ever paid. Here is who makes the games, which titles are worth knowing, what RTP to expect and where you can play them legally in Ontario.
Who is Microgaming?
Microgaming was founded in 1994 on the Isle of Man and is often credited with the first online casino software. Since 2022 its game portfolio is distributed by Games Global, so many titles now appear under that name.
What are the best-known Microgaming games?
- Mega Moolah: progressive jackpot slot famous for multi-million payouts (RTP 88.12% in the standard version).
- Immortal Romance: vampire-themed slot with the Chamber of Spins feature (RTP 96.86% in the standard version).
- Thunderstruck II: Norse-themed slot with the Great Hall of Spins (RTP 96.65% in the standard version).

What RTP should you expect from Microgaming games in Ontario?
Mega Moolah shows why RTP matters: its 88.12% is low because a large share of every bet funds the jackpot. That is fine if you are chasing the jackpot, but very expensive if you are trying to clear a bonus. Not sure what RTP means? Read our RTP explainer.
Do Microgaming games count toward bonus wagering?
Slots usually count 100% toward wagering requirements, so the expected cost of wagering is simply the house edge. With Immortal Romance at 96.86% RTP, every $1,000 wagered costs about $31 on average. The formula is: expected cost = amount to wager × (house edge ÷ contribution %). You can run your own numbers in our wagering requirement calculator.
