Does the MGM Grand Millions Slot Pay Real Money?

To play MGM Grand Millions for real money, you must be registered with BetMGM Casino and be physically playing from a legal U.S. casino state where BetMGM Casino is active: West Virginia, New Jersey, Pennsylvania, and Michigan.

Not only is MGM Grand Millions one of the best slots to play online for real money, but it has also broken records for its jackpot payouts, awarding some of the largest online slot wins in history. The biggest win from MGM Grand Millions in 2023 was $2.8 million. One player even won a $1 million jackpot on a $1 slot bet. 

How To Play MGM Grand Millions

This slot game is extremely easy to play. All you really need to do is set your preferences and press “Spin.” Here’s a breakdown of exactly how to get started:

To start playing this exclusive online casino game, set your bet by clicking the “+” or “–” buttons on either side of the Bet Value. Your total bet is 20 times larger than the bet value.

Click “Max bet” to select the maximum possible bet. To start the reels rolling, click “Spin” in the middle of the screen.

“Autospin” has three options for convenient, hands-free play:

  • Number of spins: Choose the number of automatic spins.
  • Spin till win: Automatically spin the reels until the win amount is equaled, or exceeds the amount you selected in the game’s settings panel.
  • Spin till feature: Automatically spin until the next feature is triggered.

To deactivate autospin, click on “Stop spin.”

If you want to change your bet before a spin, increase the bet meter on the game screen, or the bet amount for the next spin will stay the same.

MGM Grand Millions Game Features

Here are the game mechanics you can expect to encounter when you play MGM Grand Millions.

“All Ways” Mechanic in MGM Grand Millions

Instead of traditional paylines, MGM Grand Millions uses an “All Ways” system, providing 243 ways to win in the main game and 1,024 ways during free spins. This means that winning combinations can be formed by matching symbols on adjacent reels from left to right, regardless of their exact position on each reel.

Scatter Symbols in MGM Grand Millions

Represented by the MGM Grand logo, these symbols may not have any payouts for matching combinations, but they do offer other rewards. If you land three or more scatter symbols anywhere on the reels, you’ll trigger the “Free Spins” feature. 

Wild Symbols in MGM Grand Millions

This game also includes a wild symbol which, when it lands on the reels, is randomly replaced with any of the other symbols (except the scatter), increasing your chances of making a winning combination. 

Multipliers in MGM Grand Millions

Before the Free Spins feature starts, players are taken to a mini-game where they have the opportunity to collect multipliers for the Free Spins round. During the Free Spins feature, all wins are multiplied by the awarded multiplier, enhancing the potential payouts and adding excitement to each spin.

The Bonus Wheel in MGM Grand Millions

The bonus wheel gives players the chance to win one of five different jackpot tiers. This wheel adds an extra layer of anticipation, and offers players the opportunity to claim substantial jackpot prizes.

How the Free Spins Feature Works on MGM Grand Millions

The Free Spins feature is activated when three or more scatter symbols — represented by the MGM Grand logo — appear anywhere on the reels during the main game. This triggers a bonus round that offers players additional opportunities to win without placing additional bets.

Once the feature is triggered, players are presented with a unique selection process. They’re required to choose slabs in a specific order, starting from the bottom first slab and progressing upwards. Each slab contains hidden values representing the number of free spins you could win and a multiplier.

This is where a small amount of strategy comes into play. Correctly choosing a slab will reveal the number of free spins and the associated multiplier, which are then added to the total count displayed on top of the selection area. So, you could potentially win a fair number of free spins with big multipliers. However, if you choose the wrong slab, the bonus game will end, and you’ll go to the Free Spins round with only the free spins and multipliers that you accumulated before the selection process. 

Once the selection process is complete, you’re taken to the Free Spins round, which is displayed in a 4×5 slot view. During the free spins round, all-way wins are multiplied by the awarded multiplier, significantly enhancing the potential payouts. 

It’s worth noting that scatter symbols do not appear during free spins, meaning that the feature cannot be re-triggered. However, with the potential for a substantial number of free spins and multipliers, players have ample opportunities to accumulate significant winnings during this bonus round.

MGM Grand Millions Bonuses and Jackpots

Not only does this exclusive BetMGM slot game include a fun bonus game and potentially lucrative Free Spins round, but it also features a progressive jackpot system shared across multiple BetMGM slots.

This interconnected system includes other popular titles such as Loot’en Khamun, Book of Myths, Spin & Win, Mirage Mega Magma, and Bison Fury. So, as players wager on any of these participating games, a portion of their bets is contributed to the shared jackpot pool, leading to larger and more enticing jackpot prizes.

MGM Grand Millions boasts five distinct jackpot tiers as part of the Big One Jackpot feature, each represented by a unique color on the jackpot wheel. 

  • Orange: Blitz Cash Jackpot (Initial seed: $40)
  • Red: Quick Cash Jackpot (Initial seed: $200)
  • Blue: Super Cash Jackpot (Initial seed: $750)
  • Green: Mega Cash Jackpot (Initial seed: $10,000)
  • Lavender: Colossal Cash Jackpot (Initial seed: $1,000,00)

Each MGM Grand Millions jackpot starts out with an initial seed, which BetMGM (The House) funds through the reserve system of contributing games. The seed amounts for each jackpot tier will continue to grow until someone triggers them, so players can win some very big sums. The maximum jackpot amount for this slot is an astonishing $5 million. 

How To Win MGM Grand Millions

The goal is to form winning combinations by spinning the reels and hoping that matching symbols land on adjacent reels (running from left to right). While winning is largely based on luck, it’s important to note the theoretical return to player (RTP) of the game, which is 91.81%. This may be on the lower side, but MGM Grand Millions is renowned for how often the jackpot prizes pay out. 

The reel structure numbering for winning combinations in the online slots base and free spin games is:

Base Game

0 1 2 3 4
5 6 7 8 9
10 11 12 13 14

Free Spin Game

0 1 2 3 4
5 6 7 8 9
10 11 12 13 14
15 16 17 18 19

Suppose two matching symbols appear in reels 1 and 2, followed by three of the same symbol on reel 3. In that case, it won’t count as a five-symbol winning combination, but as the following three separate winning combinations:

0, 1, 2

0, 1, 7

0, 1, 12

Winning combinations are multiplied by the total bet amount.
