(A) Any rules of play issued by the department must be obeyed.
(B) In no case shall any concessionaire or agent buy back for cash any prize from a player at a fair, nor shall any combination of prizes, articles, tickets, numbers or money be exchanged for other prizes; except, that a game may be played in such a manner that the player may accumulate up to three wins in order to win a large prize (i.e., one win/wins prizes on first shelf, two wins/wins prizes on second shelf, three wins/wins prizes on third shelf). If a game is played in this manner, only one price of play shall be allowed. Each level of prize must be plainly marked as to the number of wins.
(C) In any game, the concessionaire or agent may designate a physical line or barrier a certain distance from the target behind which the players must stand to play the game, thus preventing the agent from judging the validity of the play. If the game is trailer-mounted, the inspectors shall determine the height of the base on which the game is set.
