One platform is confirmed for Scam With Your Friends: Windows PC, on Steam. The store's own data marks Windows as supported and both Mac and Linux as not supported, and the game is a digital Steam release with no physical edition on any platform.
What the store data says, line by line
| Platform | Status | Where it comes from |
|---|---|---|
| Windows (PC) | Confirmed | Store platform data |
| Mac | Not supported | Store platform data |
| Linux | Not supported | Store platform data |
| Steam Deck | Unknown | Store compatibility field |
| PlayStation, Xbox, Switch | Not announced | No official statement exists |
| Roblox, mobile | Not announced | No official statement exists |
The Mac and Linux rows are worth reading carefully: this is not a case where the developer simply has not said anything. The store data actively marks both as unsupported, which is a stronger statement than silence.
The Roblox and mobile rumours
Short clips of the game circulating on social platforms have been folded into videos claiming Roblox and mobile versions are on the way. Neither has been announced by the developer or the publisher, and the platform data above rules out a mobile build for now. If a Roblox or mobile version ever becomes real, it will appear in the store's news feed and on the official channels listed there, not in a repost.
Steam Deck status
The store lists Steam Deck compatibility as Unknown. That is a status, not a confirmation either way: it means the developer has not submitted the review that would let Valve mark it Verified or Playable. The minimum specs include a GTX 1060 class GPU and a broadband connection, and the game streams AI-generated dialogue, so treat any claim that it "runs fine on Deck" as unverified. The system requirements page has the full spec list.
What about playing with friends on other platforms?
Since there is only one platform, there is currently no crossplay question to answer. The multiplayer page covers lobbies, and the price page explains why a second "cheap copy" from a key site is not a platform question at all but a scam risk.
