Letter Jam Rules
A cooperative deduction word game where players see everyone else's letter cards but not their own and give clues to help identify hidden letters.
Also known as: Letter Jam cooperative game, cooperative letter clue game
Letter Jam-style play is a word puzzle with asymmetric vision. The table can often see the information you need, but they must communicate it through clue words rather than simply telling you your letter.
A clue such as HONEY = 5 letters teaches the structure: each visible card fills one position in a clue word, and each player uses that position to narrow their own hidden letter.
Quick answer
Letter Jam is cooperative hidden-letter deduction. You see other players' letters but not your own, then use shared word clues to infer which letter you are holding.
