Represented by his avatar — a sprightly green figure with an eyeball for a head — Mr. Yaroshevski padded through some of the players’ spaces, teleporting to more distant one. One had floors swathed in grass and walls covered in Yayoi Kusama-like dots, decorated with cartoonish pixel art. Another was a shadowy, marble-tiled space that vaguely resembled the Frick Collection in New York, enlivened with prize Botticellis, Bruegels and a rococo “Allegory of Music” by the 18th-century French painter Francois Boucher (an unofficial loan from the National Gallery of Art in Washington).

But it was only a matter of time before we encountered the kind of identikit space beloved of dealers everywhere: luxe minimalism, polished floors, and, yes, white walls. Only the fact that the space didn’t have a roof to shield its Hilma af Klints was unusual. “People do many things,” Mr. Yaroshevski said.

Mr. Yaroshevski said that while casting around for ideas soon after founding StikiPixels in 2010, he noticed that games focused on the art world — rather than games where players made their own art — were hard to find. “It seemed crazy,” he said. “There are games for everything, even street-cleaning simulators. But not art.”
