(1) Approved variations of keno are:
(a) A straight ticket in which a player picks from one to ten numbers and wagers that the numbers will be duplicated entirely or in part from the group of numbers drawn.
(b) A split ticket consisting of two or more straight tickets written on a single keno card. Each group on a split ticket is treated as if it were a single straight ticket.
(c) A way ticket in which a player selects three or more equal groups of numbers which when taken at least two groups at a time comprise several straight ticket combinations.
(d) A combination way ticket in which a player simultaneously combines any or all of the variations described in (a) , (b) and (c) .
(e) A king ticket in which a single number, commonly known as a king number, is matched with each group of numbers selected. The king number is treated as any circled number group as used in way and combination way tickets.
(2) A group of numbers resulting from combining smaller groups for way, combination way, or king tickets may not exceed a total of ten numbers.
