The most obvious tell to me is that they all have more or less the same elated AI zombie expression. One AI tell (ish) is that the images have a lot of unnecessary details that I don't think an actual artist would bother to include. Why draw all those framed pictures? Isn't this a picture of a family playing a board game? And the architecture of that living room is a bit weird even if it's not impossible. But why draw unconventional architecture here? But there are few clear artifacts. I think maybe these are AI images that are touched up later. One surefire way to find out would be to open the boxes to check if the games depicted match the actual games. I found some pictures of the actual game from an older version, and it seems that at least on the "family" box, the game on the table is similar to the game in the box. I doubt an AI would get that right, so at least that part could be drawn by an actual artist. The people are iffy, though. https://www.amazon.com/Party-Co-Family-Packed-Challenge/dp/B0DJRKBTW4
