Strategic deduction
Mystery Figure
A hidden figure, count-only feedback, and no clock: after each guess you learn how many attributes were right (never which), and only your attempt count scores. The winning strategy is to choose guesses that split the remaining possibilities, not guesses you hope are right, and the results show your gap to information-efficient play. A staple of trading-firm cognitive assessments.
