S.D. Codified Laws § 22-25-23
As used in this chapter, the term, bingo, is that game in which each player is supplied a card, board, or electronic bingo device containing five adjoining horizontal and vertical rows with five spaces in each row each containing a number or figure therein, except for the central row with four spaces, each containing a number or figure therein and the word, free, marked in the center space thereof. Upon announcement by the person conducting the game of any number or figure appearing on the player's card, board, or electronic bingo device, the space containing the figure or number is covered by the player. If the player covers all five spaces in any horizontal or vertical row, covers four spaces and the free space in a five space diagonal row, or covers the required combination of spaces in some other preannounced pattern or arrangement, the combination of spaces covered constitutes bingo. The player to first announce bingo is awarded money, merchandise, or some other consideration by the person conducting the game. For purposes of this section, an electronic bingo device does not include any device which may be activated for play by a player inserting coins, tokens, tickets, vouchers, or similar objects of value or which is capable of dispensing coins, tokens, vouchers, tickets, or any similar object of value.
