An electronic gameboard (1) includes a foldable sheet, each side of which is divided into first and second sections. On one side, a conductive ink printed circuit, including a plurality of switch contact pads (10, 11) is laid down such that upper contacts (10) register with lower contacts (11) to effect a switch pair when the sheet is folded. A spacer expedient of dielectric ink (19), thicker than the conductive ink, is employed to juxtapose the upper and lower contacts (10, 11) of each switch pair in a normally open condition such that finger pressure selectively effects a momentary closure. The printed circuit also includes traces coupling all the contacts to a decoder (55) which senses if a switch pair is closed. A gameboard layout is provided on the second side of the sheet and includes indicia identifying the position of each gameboard layout. Signal producing apparatus, such as a sound unit, responds to the closure of a given switch pair by issuing an appropriate, predetermined signal passage. In order to permit folded storage of the gameboard, one section is bifurcated by a slot which facilitates a temporary fold.
