Cashing on the drop in keno

I’ve had an interesting phenomenon happen while playing multi-card video keno over the past week and I hope the scenario works for you as well.

Most of my efforts have involved 20-card keno, which offers a myriad of betting options. I typically mark eight 7-spot cards in two mirror image patterns (for a total of 16 7-spot cards), plus four other cards that overlap the 7-spots.

Here’s how it works: Pick two rows of 10 numbers from the keno board (I usually pick the bottom two rows, but it doesn’t matter) and mark eight 7-spots under the middle eight numbers of each row.

Then with my remaining four cards, I mark matching six and eight-spots using the outside numbers.

Another pattern that I like to use is the two 2x8 boxes above and below the center line. Thus I would mark eight 7-spots in the boxes above and below the line, then overlap those with four 8-spot cards – all eight numbers in the adjoining columns, plus the two "cross-over" patterns utilizing the top left four numbers coupled with the bottom right four numbers, and the bottom left four numbers coupled with the top right four numbers.

Another pattern that I like to use is the two 2X8 boxes above and below the center line. Thus I would mark eight 7-spots in the boxes above and below the line, then overlap those with four 8-spot cards – all eight numbers in the adjoining columns, plus the two "cross-over" patterns utilizing the top left four numbers coupled with the bottom right four numbers, and the bottom left four numbers coupled with the top right four numbers.

Obviously, it’s always the goal (wish?) to have all the numbers hit, but realistically you’re hoping at least seven numbers fall into your pattern of eight 7-spots. When this happens, you’ve hit a solid 7-spot (at a payoff of 7000-1) plus six 6-of-7 jackpots (at about 400-1 each).

If you’re super lucky and catch all eight in your pattern, you will have hit eight solid 7-spots!

Mathematically, what you’re trying to do is cut down the 41,000-1 odds of hitting a solid 7-spot. Because the odds of catching seven numbers out of eight numbers marked is only 6200-1, you should catch a solid 7-spot six times more often than you would marking a solo 7-spot.

Now, let’s get back to what’s been happening lately. On occasions when my patterns could only produce a few 6-of-7 payouts over a fair amount of time, I’ve added two numbers (outside the pattern) to my eight 7-spots to create eight 9-spots.

It doesn’t matter where you add the extra two numbers: if you’re on the horizontal rows, you can pick the two unused outside numbers. If you’re using the top and bottom boxes, just grab two adjoining numbers outside the box.

Under this scenario, three times in the past week the new pattern hit 8-of-9 jackpots at a cool 4700-1. Moreover, when you catch six of your original eight numbers plus the two outside orphans, you cash TWO 8-9 cards for two jackpots.

If you catch seven of your original eight plus one of the orphans you collect just one 8-of-0 jackpot. If all eight fall into your original eight numbers (don’t cut your wrists lamenting missing out on eight solid 7-spots!), you collect only eight 7-of-9 awards (this has never happened to me).

Maybe the odds are once again mathematically at work. Ordinarily the odds of catching 8-of-9 are about 30,600-1. But since you’ve marked your 9-spot cards under 10 numbers, the odds of catching eight of those 10 numbers are only 7300-1.

Who knows, but why overanalyze something that seems to be working. Try it and let me know how you make out.
