Keno 15-spot tickets can make ways

Jul 5, 2011 3:00 AM

Yes I know most of you who play 15-spot tickets (and there are not so many of you these days) play mostly straight tickets.

In a way this is understandable because of the number of spots creating a confusing array of possibilities. Also, 15 is an odd number so that offers a hardship in way ticket creation.

Even number way tickets are more popular than odd simply because they can be split in two, sometimes several times. So in that sense the difference is more psychological than mathematical.

That being said, most players are unaware the 15-spot was the basis for several of the most popular way tickets ever played. Back in the day they were played without covering the solid 15 so it was not immediately evident you were playing it.

Since the number 15 has two prime factors, 3 and 5, it is obviously convenient to group the way ticket in groups of three or five (3-3-3-3-3 or 5-5-5).

In the first case the ticket results in a 10-way-9 and a 10-way-6. Both of these tickets were very popular back in the day, with the 10-way-9 perhaps the most played of the two.

This quite playable ticket also has a 5-way-12. If I were to play it I would go 1/15, 5/12 and 10/9 for a 16 unit ticket. The 5-5-5 split is the famous 3-way-10 that was played millions of times in the ‘50s and through the ‘70s. It was finally replaced in popularity by the 8-spot in the mid ‘70s.

I would play the 15, the 3/10 and the 3/5 for a seven unit combination/way ticket.

Of course we can’t forget another of the most popular way tickets of all time, also a 15-spot. This is the "field ticket" version of the old 4-way-9. Back in the day the 4-way-9 was typically written two different ways – the pure way ticket of 12-spots grouped 3-3-3-3 and the 15-spot "field ticket" 6-3-3-3.

The group of six is the "field" that combines with a group of three to produce three of the four 9s. It turns out the field ticket is slightly better in odds for the player.

This was unknown back in the day so the players back then must have had some intuitive notion that the field ticket was better or it would not have been so popular. Curiously, this ticket also was usually written without covering the full 15-spots.

That leads me to another of my all time favorite tickets. Take 15-spots and group them 3-3-3-2-2-2. Now the total ways on this ticket (63) include 1/15, 3/13, 3/12, 3/11, 9/10, 4/9, 9/8, 9/7, 4/6, 9/5, 3/4, 3/3 and 3/2.

I would certainly cover the 15, and the 4/9. If I could afford it I would play for sure the 9-way-8 and the 9-way-5. The eights and the fives work well together on this ticket.

Well that’s it for this week. Good luck! See you on line at [email protected]
