Mega Moolah RTP
Return to player on Mega Moolah is the share of all stakes the slot is built to pay back over a very long run, jackpot wins included. Games Global prints no figure for it. Catalogues quote 88.12% for the base game and 93.42% with the jackpot contribution, each without a source.
- Game:
- Mega Moolah (a Games Global progressive jackpot slot, first released by Microgaming)
- Type:
- Slot game
- RTP as published:
- Not printed by the game or by the studio: the client's rules and paytable carry no return-to-player line anywhere, and the studio publishes no page for this title.
- Max win:
- No ceiling covers the whole game, because the four progressive jackpots keep growing until someone wins them.
RTP on a Progressive Slot
On a progressive slot, RTP does two jobs at once: part of it pays line wins, scatters and free spins, and the rest feeds the jackpot pools. The term itself, short for return to player, means the long-run share of stakes a slot is built to hand back. Mega Moolah has four such pools (Mini, Minor, Major and Mega), and they keep growing until a randomly triggered wheel pays one of them out.

That split changes how the game feels.
The top prize on this game once reached €18,915,872.81. If the catalogues are right, about 5.30 points of the return sit in the pools rather than in line pays, a figure Games Global has never confirmed.
The rules add a twist. In capitals they say "THE HIGHER YOUR BET THE GREATER YOUR CHANCES OF WINNING THE PROGRESSIVE JACKPOT", and stop there. As far as the printed text lets anyone tell, a player on 0.25 and a player on 6.25 face different jackpot odds. One RTP figure would struggle to describe both. The studio leaves both unstated.
Mega Moolah's Rules Carry No RTP Line
Games Global prints no return-to-player figure for Mega Moolah. The game itself shows none either. We opened the studio's free client and read the rules and paytable screen by screen. Then we searched the saved text file, all 212 lines of it, for "return", "RTP" and the per cent sign. The search came back empty.
The studio's website is just as quiet: Games Global keeps no page for this title, while the old Microgaming page has gone.
That leaves the paytable as the only official maths on show. Five wild lions pay 3,750.00 at the top stake of 6.25, which is 600 times the bet. A paytable shows what a line can pay, though it stays silent about how often.
Where We Looked for an RTP Figure
| Place we checked | Publisher | RTP shown |
|---|---|---|
| Rules screens in the demo client | Games Global | none |
| Paytable at a 6.25 bet | Games Global | none, line pays only |
| Client text file, 212 lines | Games Global | none |
| Studio product list | Games Global | no page for the game |
| gambling.com catalogue | third party | 88.12% |
| casino.org and OLBG catalogues | third party | 93.42%, with 88.12% as the base inside it |
Read on ; the maker can change a screen without saying so.
Every official surface came back empty. Every number in circulation comes from a third party.
88.12% and 93.42%, Explained
88.12% and 93.42% are two catalogue readings of one game: the first leaves the jackpot out, the second adds its contribution back. gambling.com quotes only 88.12%. casino.org and OLBG lead with 93.42% and give 88.12% as the base inside it. The sites agree on the shape of the split, yet none of them names a source.

| Figure | What catalogues say it covers | Source named |
|---|---|---|
| 88.12% | base game, jackpot left out | none given |
| 93.42% | base game plus jackpot contribution | none given |
Taken at face value, the gap is the interesting part. Subtract one from the other and you get 5.30 percentage points, which would be the jackpot's slice of every stake. On a 6.25 spin that comes to roughly 0.33 feeding the pools.
Treat that as arithmetic on borrowed numbers, though, since Games Global confirms neither end of the subtraction.
The House Share Stays Unknown
Mega Moolah's house share stays unknown because the published data lack two inputs: a return-to-player figure from Games Global and the rate at which stakes feed the pools. Any house-edge number you meet is somebody's estimate.

What the studio does publish is where the pool money lands. Its win feed, read the same day, logs 1,273,063 Mini wins averaging €8.48 over two years. Mega level paid out twice in that time. By count, almost every pool win is small change. By money the picture flips: those two Mega wins took €14,709,627.50, about 23% of the 63.6 million the feed paid across all four levels, and the Mega counter held a further 15,841,588.70 unpaid on the day we read it.
Hit frequency is unpublished as well. Catalogues disagree about volatility too, calling it low, medium and high in turn, which says more about the catalogues than about the game.
Before You Trust Any Figure
Every RTP attached to Mega Moolah is a third-party number, so start by asking who printed it and whether they name a source. We do not recommend picking Mega Moolah over another slot because a site quotes 93.42% for it. The figure's origin is unknown. Other sites print 88.12% for the same game.
If a casino lobby shows you a percentage for this title, ask where it came from; otherwise you are comparing one guess with another.
One check outranks any percentage: whether the site showing it holds a licence from the regulator where you live, as that regulator's own register records it.
