The invention relates to a game board comprising, on the visible side thereof, a set of boxes comprising recesses (2) within which various conventional devices (4) are located which each integrate a retractable button (3) corresponding to sub-boxes representative of the distinct identifiable positions of the players or the identification of at least the possible numbers of games of sudoku. The retractable buttons (3) assume two stable positions selected from a folded-down position in bas-relief and an unfolded lifted-up position, one of them defining the selected active position of the respective player differentiated from the other inactive position of the retractable buttons (3). |
