Abstract: Transparent marker pieces for use on a game board such as the game of Bingo and the like contain magnetically permeable material so that they can be quickly and easily gathered up from the game board with a magnet attached, for example, to a pencil or pen used by the player and then simply wiped off the pencil and deposited in a container for the marker pieces. In the preferred construction, the magnetically permeable material in the marker does not substantially block the view through the marker of the game board beneath and so, the transparent quality of the marker is maintained.
