The City Escape Amersfoort is not a physical escape room but a self-guided outdoor game: one of twelve city editions of The City Escape franchise, played via an app in the historic city center. The story revolves around The Boulder of Amersfoort—in 1903 residents decided the famous boulder should be above ground again—and you search along real monuments for clues about where it has ended up. You buy a code online, start whenever you want and can request a hint or even the full answer at every puzzle and simply continue playing; there is no game master and no fail state. Virtually nothing can be found online about this edition: on escapetalk the Amersfoort version has not a single review, and videos or forum discussions are absent—typical for a completely automated franchise product that enthusiasts skip over.
