A board game structure of the type consisting of a plurality of playing pieces and a game board on which the playing pieces are moved having a given axis with a plurality of elongated rectilinear sliders mounted thereon for movement in side-to-side relationship to each other at a given common angle to the axis of the board. The board game has an improved detent structure for restraining each of the sliders in predetermined positions in their movement. Such improvement is based on the use of detent cam surfaces and detent cam followers held in engagement solely by the force of gravity acting on the sliders. An improvement in the structure for retaining the sliders on the game board against the force of gravity is disclosed.
