Look at the fandom, entry type, image, and the one visible AO3 work count.
Choose the side you think has more AO3 works. One number stays hidden until the reveal.
A correct answer keeps the streak alive. A miss ends the run and shows the count gap.
Change difficulty, include broader fandom entries, or try the shared daily route.
Easy
Best for learning which fandom lanes write at scale.
Normal
A steady mix of obvious calls and closer archive reads.
Hard
Better for players who already know common high-volume tags.
Extreme
Small differences matter. Use source, type, and fandom habits.
The better call is often about how much a fandom writes, not how famous the character is outside AO3.
