If you take all the numbers around the outside edge of the keno board (there are 32 of them) what is the most likely amount of numbers to come up every game?

Eight is the most likely catch on an "Edge" ticket.

As a matter of fact, since 20 out of 80 numbers are called every game (1 out of 4 numbers), for any keno ticket, one fourth of the numbers marked represents the most likely catch. This is true on way tickets as well as straight tickets. On a 12-spot, for instance, three numbers is the most likely catch. On a 28-way-6, marked with eight groups of three, six numbers (one fourth of 24) is the most likely catch.

When I say most likely catch, I really mean the average amount of numbers caught on each ticket per game. In the case of a 10-spot, if you divide 10 by 4 you get 2.5, which is the average amount of numbers that will come up over a multiple game period. So you could say that either two or three numbers would be a likely catch on a 10-spot.

Here is a chart of Keno tickets, with the most frequent catches on each one, and their attendant odds for one against:

Spots  Catch Odds
     against
1 0/1 1.33
2 0/2 1.79
3 1/3 2.32
4 1/4 2.31
5 1/5 2.46
6 1/6 2.75
7 2/7 3.06
8 2/8 3.05
9 2/9 3.16
10 2/10 3.39
11 3/11 3.59
12 3/12 3.57
13 3/13 3.67
14 3/14 3.86
15 4/15 4.00

Naturally, when there are more possible catches, the payouts are distributed over more possibilities. In general, the more numbers you play the more chance you have of hitting something that will pay something back to you. This generalization is tempered of course by the particular payouts on each ticket. On a scale of one to five spikes, with five being the highest, Keno Lil rates playing more numbers at 4.
