Just One Scoring: Correct Answers, Wrong Guesses & 13-Card Score
Just One is fully cooperative. The group tries to finish as close as possible to the maximum score of 13.
Correct answer: +1 point
Keep the current mystery card as a scored card. It contributes one point to the final team total.
Wrong answer: lose two cards
Discard the current mystery card and the top card of the deck. This removes two potential points from the 13-card game.
No answer: lose one card
If the active player chooses not to guess, discard only the current mystery card. The team loses one potential point but avoids the extra penalty for a wrong answer.
Maximum score: 13
If every mystery card is guessed correctly, the group scores 13 out of 13. Lower totals are evaluated against the current rulebook’s cooperative score table.
