Is 'anker games . com' the real website address?

No. The working destination for this catalog is ankergamess.net. The '.com' phrasing is a common way people type the brand into a search engine, which is why this support page exists to direct that intent to the correct site.

The catalog is presented as a free download destination, with no paid tier described in the source data. Check individual game pages to confirm details for a specific title.

What Windows versions are supported?

Windows 10 and Windows 11 are the stated target for the catalog. Individual games may have their own requirements, so review the game page before downloading.
