Abstract
Abstract A combined calculator and puzzle game device including a calculator cover-board which is provided with guide pieces confined to intersecting guide grooves. Game pieces which have projecting necks are mounted on the guide pieces by inserting the projecting necks into the guide grooves allowing them to be slid along the guide grooves, but not be removed. The game pieces can be rearranged on the cover board to bear a particular pattern or a combination of characters. When the game pieces are depressed, they push rubber keys placed therebelow so as to operate the calculator.
