Mega Moolah slot review: progressive jackpots, the wheel and RTP
Microgaming's 2006 progressive slot in which a random wheel awards one of four jackpots: Mini, Minor, Major or Mega.
Mega Moolah is Microgaming's progressive jackpot slot from 2006, now part of the Games Global portfolio. It has five reels, three rows and 25 lines, plus a jackpot wheel that awards one of four progressive prizes: Mini, Minor, Major or Mega. The Mega Moolah slot's listed RTP of 88.12% is low because part of every stake feeds those jackpots, and the base game is rated low volatility.

How the Mega Moolah jackpot wheel works
The jackpot bonus is not won by lining up symbols. The wheel appears at random, and once it does, it awards one of the four tiers. Progressive jackpots grow with a share of the stakes placed on the game until one is won, then start again from their base value.
Jackpot sizes: what to rely on
Sources disagree on the starting value of the Mega tier, and the current amounts change with every stake, so this page does not quote a figure. The jackpot display in the game, or in the casino lobby, is the only current number.
RTP 88.12%: what the low figure means
An RTP of 88.12% (one database lists 93.42%) is well below most slots reviewed on this site. The difference is the jackpot contribution: a share of each stake goes into the prize pools rather than the base game's returns, so unless a jackpot lands, the game returns less over time than a standard slot with a higher RTP. Low volatility describes the base game only. See RTP explained.
Free spins and wilds
Outside the wheel, Mega Moolah is a plain game. Wilds substitute and double any win they complete, and the free spins round gives 15 spins with a 3x multiplier on wins. These features pay modest amounts compared with the jackpots.
Mega Moolah UK: stakes, spin offers and versions
At GB-licensed casinos the online slot cap of £5 per spin, or £2 if you are 18 to 24, applies to Mega Moolah like any other slot. Searches for Mega Moolah free spins with no deposit are common; any such offer is a promotion with terms, so check spin value, expiry, any cap on winnings and wagering, which GB rules cap at 10x on bonus funds. The network includes many versions, such as Mega Moolah Isis, Absolootly Mad, Thunderstruck II Mega Moolah and Immortal Romance Mega Moolah, each with its own base game. The jackpot slots page compares formats.
