Mega Vault Millionaire Slot Machine
Mega Vault Millionaire is an exclusive progressive slot game available at Casino Rewards member casinos.
Released in 2019 and commonly listed as a title from Aurum Signature Studios, Mega Vault Millionaire has become one of the best-known exclusive games in the Casino Rewards network. It is notably available at Quatro Casino.
Mega Vault Millionaire is a progressive jackpot game linked to the Mega Moolah ecosystem. The classic version features stakes from around €0.25 to €6.25 per spin, depending on the casino and account currency.
The minimum stake remains eligible for the progressive feature. A higher stake can increase the probability of triggering the Bonus Vault feature on a given spin, but it also increases the cost of each round and never guarantees a jackpot.
Mega Vault Millionaire is Played Internationally
Mega Vault Millionaire is available at several Casino Rewards casinos and supports different currencies depending on the operator and player account.
Its luxury theme, progressive jackpots and bonus features are among the game’s main characteristics.
The slot is designed for compatible desktop and mobile devices and can generally be played directly through a web browser.

- Luxury and millionaire-inspired theme.
- 5 reels, 3 rows and 25 paylines.
- Playable on compatible desktop, mobile and tablet devices.

Mega Vault Millionaire can be found at Quatro Casino and may also be available at other Casino Rewards casinos such as Zodiac Casino and Grand Mondial. Game availability can change according to the casino and jurisdiction.
PLAY AT QUATRO CASINO
After opening and funding an account at a casino offering the game, Mega Vault Millionaire can usually be found in the slots or progressive jackpots section.
Once the game loads, check the total stake displayed before pressing the SPIN button.
New Quatro Casino customers can also take advantage of a welcome offer. The current promotion provides up to 700 free spins over seven days, plus a first-deposit bonus of up to €100 depending on the deposit amount.

Progressive Jackpot Levels
Mega Vault Millionaire features four progressive jackpot levels:
- MINI
- MINOR
- MAJOR
- MEGA
Unlike the original Mega Moolah bonus wheel, Mega Vault Millionaire uses a Bonus Vault Wheel mechanic.
When the progressive feature triggers, the player can move through different jackpot stages, with special keys providing access to higher levels.
The MINI is the first jackpot level, followed by MINOR, MAJOR and ultimately MEGA.
The exact jackpot values depend on the currency and the amounts displayed in the game. Progressive jackpots then continue to grow until they are won.
How Much Should You Bet?
Many players assume that they need to bet big to be eligible for a large jackpot. This is not the case with Mega Vault Millionaire: the minimum stake can also trigger the progressive feature.
However, the size of the bet can affect the probability of triggering the Bonus Vault Wheel on an individual spin. A higher stake may increase that probability.
This does not mean that a larger bet guarantees the bonus feature or a jackpot. It also means more money is being wagered on every spin.
High Bets
A higher stake can increase the probability of triggering the Bonus Vault feature on a given spin.
This should not be interpreted as a strategy for predicting or forcing a win. The trigger remains random, and playing at a higher stake directly increases the amount spent per round.
When the Bonus Vault feature appears, the result of each stage determines whether a jackpot is awarded or whether the player progresses to another jackpot level.
Low Bets
Mega Vault Millionaire remains eligible for its progressive feature even at the minimum stake.
Lower stakes mainly reduce how quickly a playing budget is spent. They do not make a jackpot more predictable, but they allow players to access the progressive mechanic without using the maximum stake.
Whatever stake you choose, set a budget before playing and do not increase your bets simply because the bonus feature has not appeared.
Mega Vault Millionaire Winners
Mega Vault Millionaire has produced several significant progressive wins since its release.
The most notable result currently published by Casino Rewards occurred on June 17, 2023. A Canadian player identified as J.T. won:
CA$8,312,798 at Quatro Casino.
Casino Rewards states that J.T. was the first player to win the Mega Jackpot on Mega Vault Millionaire™.
This result should therefore be described specifically as a Mega Vault Millionaire jackpot rather than as a win on the original Mega Moolah slot.
Other progressive wins are regularly published across the Casino Rewards network. Past results, however, do not predict the frequency or size of future jackpots.
About the Game Developer
Mega Vault Millionaire was released in 2019 as an exclusive Casino Rewards progressive slot.
The game is commonly listed in current game databases and Mega Moolah series references under Aurum Signature Studios. Some older references also associate the title with the wider Microgaming platform on which many Casino Rewards games were originally distributed.
For that reason, the clearest description is that Mega Vault Millionaire is a Casino Rewards exclusive progressive game, commonly attributed to Aurum Signature Studios and linked to the Mega Moolah jackpot ecosystem.
Its gameplay differs from the original Mega Moolah slot through its vault theme and multi-stage progressive bonus mechanic.
Mega Vault Millionaire and Mega Moolah
Mega Vault Millionaire shares elements of the Mega Moolah progressive jackpot ecosystem, but the two games are not identical.
The original Mega Moolah uses its classic jackpot wheel to award one of four jackpot levels when the progressive feature triggers.
Mega Vault Millionaire instead uses a vault-themed feature with successive jackpot stages and keys that can provide access to higher jackpot levels.
It is therefore more accurate to describe Mega Vault Millionaire as a Casino Rewards progressive game linked to the Mega Moolah network rather than as an identical version of the original Mega Moolah slot.
Fairness and Random Outcomes
Mega Vault Millionaire uses a random number generator to determine game outcomes.
This means previous spins do not predict future results, and there is no betting pattern that can guarantee the progressive feature or a jackpot.
Players should check the technical information available inside the game and verify the regulatory status and terms of the casino they use.
For players in Luxembourg, it is also important to confirm that the casino currently accepts residents of the country and to review its payment, bonus and withdrawal conditions before depositing.
