Beyond complicated, into the realm of hairy, is the 190-way 8-spot ticket. Nearly every keno brochure features this to entice players into what looks like it must be a sure thing. The player draws a horizontal line to divide the card into upper and lower halves. Then draw a vertical line between each column as well. This has the effect of dividing the card into 20 columns of 4 numbers each, with the intent of playing all possible ways of forming 8-spot tickets from pairs of columns of 4 numbers each. Since it takes two columns to form an 8-spot, and we have 20 columns, there are a total of C(20,2) = 190 ways to combine 2 columns, i.e., create 8-spots.

If you were to play this ticket at the $1 rate it would cost you $190 per game. You are welcome to make that wager, but the casinos usually allow you to bet less than the nominal minimum when you are playing way tickets. For example, many casinos will let you bet 25 cents per way on this type of ticket. At the 25-cent level you would write this up as:

(ticket with $47.50
lines drawn 190/8
all over it) 25c

Since you are playing 25 cents per way, any payoffs would be at one-fourth of the $1 payoff scale. When the numbers are drawn for this ticket you hope an entire column of 4 lights up, then it's just a matter of waiting to see how much you'll collect.
As you can see, way tickets can be both expensive and exciting. But like combination tickets they are really nothing more than keno shorthand for a large number of individual tickets. Consequently they offer no financial advantage or disadvantage over regular tickets.
