SignSteal

SignSteal is the home of daily baseball mind games. Every day, one mystery big-league player steps into the box — your job is to figure out who.

Four ways to play, one mystery to solve each day.

Who's in the Box? Guess today's mystery MLB player in 9 tries. Every guess colors five clues — Team, Division, Position, Arm, Debut — so you can close in on the answer guess by guess.

Connect 4 Sixteen players, four hidden groups of four. Find them all before four mistakes end your run.

Beat the Clock Name the player from an escalating trail of clues before the clock runs out. Choose Present-day rosters or Legends, and climb the ranked leaderboard.

Lineup A real historical game's starting lineup, shuffled. Drag the cards back into their true batting order — one minute on the clock, no do-overs.

Progression Earn Baseballs by playing, unlock titles and achievements across all four modes, and chase Bronze, Silver, and Gold in the Weekly Series.

New puzzles every day. No account required — just pick a name and start playing.
