Mechanical game device

A game device wherein the movement of games balls by gravity from selectable holes through a changeable passage means to receiver pockets in accordance with a concealed code provides facts to the user from which to deduce the concealed code, comprising:

• a base block having a longitudinal axis, a top face adapted to be located in a plane that is tilted relative to the horizontal and first, second, and third ball receiver pockets;
• a plurality of code blocks adapted for insertion longitudinally in said base block in interchangeable side-by-side assembled relation laterally adjacent to one another and having a predetermined orientation relative to said base block, each code block having a top face with a longitudinal column of uniformly spaced, vertical holes perpendicular to the top face that align laterally with the vertical holes of adjacent code blocks to form lateral rows of holes, one hole of a column being a code hole and the other holes of that column being non-code holes;
• said base block having a plurality of upwardly facing holes in and perpendicular to its top face arranged in longitudinal columns and lateral rows, said base block holes being in vertical axial alignment with the vertical holes of the longitudinal columns of holes and lateral rows of holes of the assembled code blocks;
• first means defined by said code blocks and said base block for conveying a ball inserted in the code hole of one of said code blocks, by gravity, to the first ball receiver pocket;
• second means defined by said code blocks and said base block for conveying a ball inserted in one of said non-code holes in the same lateral row as one of the code holes, by gravity, from its hole in that row to the seconde ball receiver pocket;
• and
• third means defined by said code blocks and said base block for conveying a ball inserted in a non-code hole in a lateral row that has no code holes, by gravity, to the third ball receiver pocket.
