You Don't
Know Ball
Guess the mystery NBA, NFL or MLB All-Star from clues. Open as few clues as you can. The fewer you need, the more points you get.
- Daily: choose NFL, NBA or MLB. Same mystery player for everyone, a new one every day.
- Free Play: unlimited players. Tap Filters to pick the league, years, positions and difficulty.
- Talk your trash: challenge a friend, race them 1v1, or start a group with your chat.
Who's in it
2,404 players who made at least one NBA All-Star, NFL Pro Bowl or MLB All-Star team and played in 2000 or later. Special teams Pro Bowlers (kickers, punters, returners and special teamers) are in too. Find them under ST. Teams include moves through October 2026.
Daily YDKB
Every day you choose your sport: NFL, NBA or MLB. Each one has a mystery player that's the same for everyone. Once you get him or give up, it's locked in for the day. Want more? Play the other two. Play a Daily every day to build your streak, then tap Share to send your result and a link with your score to beat. New ones drop at midnight Central. Missed a day? Play it under Past Dailies (it won't count toward your streak).
Challenge a friend
Finish a player, then tap Challenge a friend. They get a link to the same player with your score to beat. Fewer clues wins.
1v1 Race
Tap 1v1 Race, start a race and send the link. When your friend opens it, you both get the same mystery player after a 5-second countdown. First to name him wins.
Groups
On the leaderboard, tap My Groups, start a group and invite your group chat. Every Daily you play scores points for the week (10 for a 1-clue solve, down to 1). The board resets every Monday, and last place gets roasted.
My stats & badges
Tap My stats for your Daily record, how many clues you usually need, your best streak and 12 badges to unlock.
Free Play
Unlimited mystery players. Every player you get right adds points to your total and the leaderboard. Tap Filters to choose who shows up:

- Years: 2020–2026, 2015–2020, 2010–2014, 2005–2009, 2000–2004. Tap one or mix several. 2000–2026 means everyone.
- Positions: tap one or more (QB, WR, PG, SP and so on) to only get those players. NFL ST is special teams: tap it, then pick K, P, KR (kick returners), PR (punt returners) or ST players (gunners, coverage guys and long snappers).
