Regulation 4 Bingo cards
Save as the Commissioners may allow, every card of a kind that may be used once only, which is issued or to be issued by the promoter to any person for the purpose of playing bingo, shall be marked with an identifying number in a series not less than 99999, and, if the Commissioners in any particular case so direct, with the amount of money to be paid for it by or on behalf of the person to whom it is so issued.
Cards of the kind described in paragraph (1) above shall be issued to players by the promoter in numerical order, and where they are issued to players at more than one point on the premises, the series issued at each such point shall be different from that issued at any other such point.
Every bingo-promoter who intends to provide cards of a kind that may be used more than once shall display, in such a position that it can be easily seen and read by every player, a notice stating the amount of money paid or to be paid by or on behalf of a player for each such card entitling him to use it once.
Save as the Commissioners may allow, every bingo-promoter shall keep a record showing for each day, in respect of every type of card of the kind described in paragraph (3) above, the amount of money paid for the use of it by or on behalf of each player on each occasion, and the number of occasions on which it was used, and shall make the entries in the record not later than 48 hours after the end of each week.
