Mega Moolah Slot Review

The safari slot behind some of the biggest online jackpot wins ever recorded. A simple 25-line game with a four-tier progressive jackpot wheel that can trigger on any spin.

Our Take: You play Mega Moolah for one reason: the jackpot. The base game is basic and the RTP is low, but no other slot has a track record like it.

Mega Moolah Slot Overview

The mega moolah slot is a 5-reel, 25-payline safari game first released by Microgaming (now Games Global) in 2006. Its four progressive jackpots are linked across many casinos, which is why the top prize regularly reaches millions.

  • The jackpot wheel can trigger at random on any paid spin.
  • Base RTP is 88.12% because part of every bet funds the jackpots.
  • Free spins triple all wins, and wilds double them again for up to 6×.

How Mega Moolah Pays

Mega Moolah uses a 5×3 grid with 25 paylines. The lion is the Wild: it substitutes for other symbols and doubles any win it's part of. Monkey scatters pay anywhere and trigger free spins. Line wins are frequent (about one spin in two) but usually small.

How the Mega Moolah Jackpot Works

The jackpot wheel can be triggered at random after any paid spin, and higher bets slightly increase the chance. Once it starts, you're guaranteed one of four jackpots: Mini, Minor, Major or Mega. The wheel is weighted towards the smaller prizes, so the Mini and Minor are the most common results.

The Mega jackpot starts at one million in the casino's currency and grows with every bet placed on the network until someone wins it. In 2015, a UK player won £13.2 million, which Guinness World Records certified as the largest online slot jackpot payout at the time.

Mega Moolah Free Spins

Three or more monkey scatters award 15 free spins with all wins tripled. Because the lion Wild doubles wins it's part of, a wild win in free spins pays 6×. Free spins can be retriggered. Many casinos also offer "Mega Moolah free spins" as promotions; those are casino offers with their own wagering, not part of the game itself.

Mega Moolah Versions: Immortal Romance, Atlantean Treasures and More

The jackpot wheel appears in several games, not just the safari original. Popular versions include Immortal Romance Mega Moolah, Atlantean Treasures Mega Moolah, Absolootly Mad Mega Moolah and Fortunium Gold Mega Moolah. Each has its own base game and RTP but uses the same four-tier jackpot idea. This review covers the original Mega Moolah.

What Other Reviewers Say About Mega Moolah

Every major review site describes Mega Moolah the same way: a dated, basic base game attached to the most famous jackpot in online slots. Reviewers consistently list the RTP at 88.12% and point out that about 5% of each bet goes to the jackpots. Most say the hit frequency of around 46% keeps the game ticking over, but warn that many of those "wins" pay back less than the stake.

What reviewers like

  • Life-changing progressive jackpot
  • Long record of verified big wins
  • Frequent small wins and simple rules

Common criticisms

  • Low 88.12% RTP
  • Dated graphics and sound
  • Usually excluded from bonus wagering

Mega Moolah RTP, Volatility & Jackpot Odds

The total RTP is 88.12%, well below the industry average, because a slice of every bet goes into the progressive jackpots. Volatility is low to medium in the base game. Over a normal session, expect to lose faster than on a 96% slot; the trade-off is a shot at the Mega jackpot.

Mega Moolah Demo and Real Money Play

A demo lets you try the base game and free spins, but the progressive jackpots can only be won in the real-money version. If you play for real money in Canada, use an amount you're happy to spend on entertainment, and remember most bonuses don't count toward wagering on this game.
