That was fun and definitely a bit challenging to figure out—I scored 3677, landing in the top 46%, with an average of 9.2 years.<p>As for some (hopefully constructive) feedback: I think the year selection slider could benefit from a few adjustments. If an image is from the distant past—say, pre-1950s—it might make more sense to use decade-based precision rather than individual years. For example, a black-and-white photo had me way off that caused me to lose 20 years of my life :). It would be helpful if such images were categorized more broadly, something like “191x”.<p>For mid-century images (roughly 1960–1990), a 5-year interval could strike a better balance. I came across one from that era and was six years off. And for more recent images, say post-2010, a one-year precision feels reasonable.<p>Of course, this suggestion mainly applies if we're deducing the year based on visual cues like clothing, hairstyles, and the environment. If the game is intended more as a quiz based on the text descriptions under the images, then it shifts more into trivia territory—and that’s a different type of challenge altogether.
