The direct answer: MGM Grand Detroit is not one of the Detroit venues documented in this article's reference set
If you arrived expecting a single, verified number for how many slot machines sit on the floor of MGM Grand Detroit, the honest answer is that this article cannot give you one. The reference sources this article draws on document two Detroit casino properties in detail — Hollywood Casino at Greektown and MotorCity Casino Hotel — but MGM Grand Detroit is not among the venues for which a slot-machine figure is recorded here.
That does not mean the number is unknowable. It means the number is not in the public reference material this article is built from, and the responsible move is to tell you exactly where the current figure lives, rather than to guess one.
What is documented for Detroit's other two casino properties
Two Detroit casino venues do have documented slot-machine totals in publicly published reference sources. These figures describe a specific point in time, not necessarily today, because properties reallocate floor space, retire older machines, and add new ones as they renovate.
For MotorCity Casino Hotel, the documented figure is approximately 2,500 slot machines. That number appears in the same reference passage that records 59 table games, 400 hotel rooms, and 67,000 square feet of meeting and convention space. The word "approximately" is part of the source itself — the property's machine count is not presented as an exact census even in the reference material.
For Hollywood Casino at Greektown, no slot-machine total appears in the documented fields at all. What is documented is 128,170 square feet of gaming space, 1,000 hotel rooms, and a 2000 opening year. That illustrates a wider point: two venues in the same city can have very different levels of publicly documented detail, and a missing field is not the same as a small or unimportant venue.
| Venue | Documented slot machines | Documented table games | Documented gaming square feet | Documented hotel rooms | Measurement type |
|---|---|---|---|---|---|
| MotorCity Casino Hotel | 2,500 (approximately) | 59 | 67,000 | 400 | Publicly published reference source, point-in-time |
| Hollywood Casino at Greektown | Not documented in this article's sources | Not documented in this article's sources | 128,170 | 1,000 | Publicly published reference source, point-in-time |

Why slot counts are harder to compare than they look
Even when two venues both have published slot-machine numbers, comparing them directly is less straightforward than it appears. The reason is that properties do not all count the same categories of machine the same way.
Some counts include electronic table games — video blackjack, electronic roulette, and similar terminals — while others count only traditional reel and video slots. Some properties separate out video poker terminals, and some do not. A venue that has recently converted a bank of mechanical reels to video screens may report a different number than a venue that kept the older machines in place.
Gaming square footage carries the same ambiguity. A figure described as "gaming square feet" may include only the casino floor itself, or it may include adjacent areas such as high-limit rooms, poker rooms, and sportsbook space. Two venues with identical slot counts can therefore have very different gaming-square-footage figures, and two venues with identical gaming-square-footage figures can have very different slot counts.
Hotel room counts introduce yet another variable. A room total may include only the main hotel tower, or it may bundle in an adjacent tower, suites, or rooms that are managed separately. None of these distinctions is visible in a bare number.
Where the current MGM Grand Detroit figure lives
The authoritative current slot-machine count for MGM Grand Detroit is held by the property itself and by the regulator that oversees Michigan commercial casinos. Neither figure is something this article can quote, because neither appears in the reference set this article is built from.
What you can do is check the property's own published materials. Casino operators routinely publish machine counts in press releases, annual reports, and on their corporate websites, and those figures are updated when the floor changes. The Michigan gaming regulator also publishes information about commercial casino operations in the state, and that is the channel to consult for a regulator-side figure.
When you look at either source, note the date attached to the number. A slot count published in a 2023 annual report describes the floor as it stood at that time, not necessarily as it stands when you read this.
What to confirm before you go
If you are travelling to Detroit and the slot count matters to you — for instance, because you are comparing properties for a stay — there are a few changeable items worth confirming through the property's own channels.
- The current slot-machine figure, as published by the property or the state regulator, with the date it was last updated.
- Whether the count includes electronic table games or only traditional slot and video poker machines.
- Whether the gaming floor has been reconfigured since the last published count, which would make the older number stale.
- Parking, hours, and any entry requirements, none of which are documented in this article and all of which change.
The property's own website and guest services line are the channels that hold the current answers. This article can tell you what is documented for Detroit's other two casino venues and why slot counts resist easy comparison, but it cannot stand in for the property's own current published figure.
FAQ
Why doesn't this article state how many slots MGM Grand Detroit has?
Because the slot-machine total for MGM Grand Detroit is not present in the publicly published reference sources this article draws on. Two other Detroit venues — MotorCity Casino Hotel and Hollywood Casino at Greektown — are documented, but MGM Grand Detroit is not. Stating a number without a source would be fabrication, so the article instead explains where the current figure is published and what to confirm.
Is MotorCity's documented 2,500-slot figure still accurate today?
The figure of approximately 2,500 slot machines is what the publicly published reference source records for a specific point in time. Casino floors change as machines are retired, added, or moved, so the number should be treated as a documented historical figure rather than a live count. The property's own current published materials or the Michigan gaming regulator hold the up-to-date figure.
Why do different sources give different slot counts for the same casino?
Because sources count different categories of machine. Some include electronic table games and video poker terminals; others count only traditional slot machines. Floor reconfigurations also change the number over time, so two sources published in different years can both be accurate for their respective dates. The only way to compare like with like is to check what each count includes and when it was published.
