Probe is a parlor game introduced in the 1960s by Parker Brothers. It is reminiscent of the simple two-person game Hangman, whose object is to guess a word chosen by another player by revealing specific letters. Probe extends the number of players to a maximum of four and introduces additional game elements that increase the levels of both skill and chance. Like Hangman, each player has a secret chosen word. But unlike Hangman, the game ends when the last word, not the first word, is revealed. All players remain in the game until the end.
