ABOUT FANSLEUTH
Ask smart. Find the player.
An independent guessing game for curious baseball fans.
FanSleuth turns baseball knowledge into a mystery. Instead of answering a list of trivia questions, you ask the questions: find out what fits, rule out what doesn't, and work toward one player.
Daily Sleuth
One shared mystery for each calendar date.
Unlimited
Practice whenever you want with optional filters.
Challenge Friends
Pick the player and compare results with friends.
Built on facts, with room to learn
Roster, statistics, and player information are refreshed on a schedule. Baseball records use MLB data, while supported biography facts use referenced public sources. Coverage varies by player and topic.
Missing information should not become a “no.” When a fact cannot support a reliable answer, the game gives a free retry. Existing rounds retain their original player snapshot.
A game that keeps improving
FanSleuth is currently in private beta. Player feedback helps improve question recognition, clarity, and the way rounds feel. Found something wrong? Tell us what happened.
