The Mystery Six

The Mystery Six is a rare and enigmatic pinball machine from Rube Gross & Company, manufactured in October 1934. As a pure mechanical game from pinball's formative years, it holds significant importance in the history of the game.

Gameplay on the Mystery Six is characterized by its unique blend of luck, skill, and mystery. The machine features 7 advance holes, with 2 consistent ones and 5 mysterious holes that add an element of unpredictability to gameplay. Players navigate the ball through two "FORWARD MARCH" holes, which can advance the ball into either of the top two mystery holes or even release additional balls in out-ball gates. This combination of strategy and chance makes the Mystery Six a fascinating example of early pinball design. The locking back door can be removed to slide out the playfield, allowing a worn playfield to be replaced with a new one.

The machine's design is noteworthy for its use of all hardwood veneer in a grand-piano finish, reflecting the style of the era. The manufacturer advertised it as 44 inches long by 22 inches wide, though one example listed for sale was measured at 60 inches long, 25 inches wide, and 36 inches high, suggesting some uncertainty or variation in surviving specimens. It was marketed with the tagline "Action... what they want! Skill with a dash of mystery and luck makes them stay and play it!" The Mystery Six's mystique is further enhanced by its scarcity, making it a sought-after find for pinball collectors and enthusiasts.
