| Processor | 64-bit required; model TBA |

| Memory (RAM) | TBA |

| Storage | TBA |
| Steam Deck rating | Not listed |
What is confirmed
Steam's system requirements section has a minimum block and a recommended block. Both require a 64-bit processor and operating system. The remaining fields were marked TBA when we checked.
The Bandai Namco Store page for the PC digital edition repeats the same 64-bit requirement and TBA notes. Two official listings agree, which confirms that the full specification had not been published. They are publisher information, not independent hardware tests.
In practice, a 32-bit system will not run the game. Beyond that, the official pages do not tell you whether a particular PC is enough. Any specific number you see elsewhere did not come from these listings.
Kairosoft develops the game and Bandai Namco Entertainment publishes it on Steam as app 3905010. The requirements on that page are the ones that apply to your purchase. Requirement tables on unofficial sites should be compared against it before you trust them.
Minimum and recommended specs
A full requirements table usually lists processor, memory, graphics, DirectX version and storage. For this game, those fields were still TBA in both blocks. We show them as TBA rather than estimating values.
We will update the table as soon as Steam or Bandai Namco publishes the details. The checked date will change so you can see when the information was last confirmed. Until then, the 64-bit requirement is the only hard line.
- Processor: 64-bit required, model TBA
- Operating system: 64-bit required, version TBA
- Memory: TBA
- Graphics: TBA
- Storage: TBA
Why we do not estimate requirements
It is tempting to guess that a pixel art game will run on almost anything. However, the art style alone does not establish that an old laptop or integrated graphics will be supported. Only the official listing or real tests can confirm that.
We also do not copy requirements from older Kairosoft games. Each game has its own engine settings and content. Mobile app sizes are not a guide to the PC install size either.
Steam Deck, Mac and Linux
The Steam page had no Steam Deck compatibility rating when we checked. Native Mac and Linux versions were not confirmed in any source. The official platform list names Windows PC through Steam.
If you plan to play on Steam Deck, wait for Valve's compatibility rating on the store page. Mac and Linux players should check the Steam page for any change in supported systems. We will note updates here.
How to check your PC
On Windows, you can see whether your system is 64-bit in the system information settings. That confirms the one requirement that has been published. It is the first thing to check before pre-purchasing.
When the full requirements appear, compare your processor, memory and graphics card with the minimum block. Steam's store page is the primary source to use. The Bandai Namco Store page is a useful second official reference.
Recheck list before you buy
Pre-purchasing now means buying before the full requirements are known. If you are unsure about your PC, you can wait for the details to appear. A short recheck list helps when they do.
- Confirm your Windows installation is 64-bit.
- Check the Steam page for updated minimum and recommended specs.
- Look for a Steam Deck rating if you play on Steam Deck.
- Compare the storage requirement with your free space.
- Check the date the requirements were last updated.
Other PC details on Steam
The Steam page lists single-player, Steam Achievements, Steam Cloud and Family Sharing. It showed a release date of October 22, 2026 and a pre-purchase option when we checked. The publisher's announced date is October 23, 2026.
Kairosoft developed the game and Bandai Namco Entertainment publishes it. The PC version is the same restaurant management simulation as on other platforms. Our Steam page summarises everything the listing shows.
Performance and benchmarks
No frame rate target, resolution option or benchmark had been published. We found no independent PC performance test either. We therefore make no claim about how the game runs on specific hardware.
After launch, we will add tested notes with the hardware, settings and game version used. Results will be labelled as our tests, not official requirements. If they differ from the official table, the official table remains the reference.
Not on PC? Other options
If your PC is not suitable, the game is also announced for Nintendo Switch, Nintendo Switch 2, iOS and Android. The App Store listing we checked required iOS 13.0 or later. A minimum Android version had not been confirmed.
Saves are not confirmed to move between platforms. Choose the device you want to keep playing on. Our platforms page compares every version.
Requirements on other platforms
If you are comparing devices, the other versions publish a little more. Nintendo's US Switch 2 listing showed an estimated size of 292 MB. The App Store listing we checked required iOS 13.0 or iPadOS 13.0 or later.
These figures do not transfer to PC. A console download size or a mobile OS version says nothing about the PC install size or hardware needs. Only the PC listings can answer PC questions.
Where to find updates
The Steam store page is the first place updated requirements will appear. Scroll to the System Requirements section near the bottom of the page. The Bandai Namco Store PC page is a second official reference.
We recheck both pages and update the table on this page when they change. The checked date at the top shows when we last confirmed the information. If you spot a change first, our contact page explains how to tell us.
System requirements FAQ
Will it run on 32-bit Windows? No, both official PC listings require a 64-bit processor and operating system. That is the one requirement that has been published.
Will it run on my laptop or integrated graphics? That cannot be confirmed until the full requirements are published or the game is tested. Pixel art alone is not proof of low requirements.
How much storage do I need? Storage was still marked TBA on both PC listings. Check the Steam page before launch for the final figure.
