Advantage Keno Play

[mickeycrimm]

Here's a breakdown of the Quick Cash video keno game. You can see a pic of the game below. Anyone is welcome to critique my layman's math:

There are 3 compartments to the game.

1. Main Game
2. Hit 4 Meter
3. Hit 5 Meter

Both meters start at zero.

In the pic I'm playing a 2-spot. There's a reason for that. I have a choice of playing anywhere from 2 numbers to 10 numbers for the same meter. The 2-spot is about .1% better than the other numbers. Plus, it's very easy to capture all of the value with the 2-spot. The cycle in this game is 1551. If you play a 6-spot the odds of 6 out of 6 is 7753. So you won't capture that value on most plays. The 2-spot is the lowest variance.

You can see the bet is 75 cents. And the 2-spot pays $6.25. That's 8.3333 units. The chance of hitting a 2-spot is 16.63158. You can check this on the Wizard Of Odds Keno Calculator. But here's what the math looks like:

C(80,2) = 3160 total 2-spot combinations in an 80 ball tank.

C(20,2) = 190 combinations in which you will hit the 2-spot.

3160/190 = 16.63158

So the main game payack is:
8.3333/16.63158 = 50.1%.

Now for the meters. These are not conventional meters. A percentage of the wager is not going into these meters. For the Hit 4 meter when you catch 3 of the 5 Vault Bonus Picks it puts 1 unit into the Hit 4 meter.

When you catch 4 of the 5 Vault Bonus Picks you are awarded 10 units plus whatever money is in the Hit 4 meter.

The freq. of catching 3 of 5 is 11.93 (you can check these freqs. on Wizard of Odds). The freq. of catching 4 of 5 is 82.7

82.7/11.93 means you will average putting 6.93 units into the Hit 4 meter per 82.7 games. Adding in the extra 10 units means 16.93 units per 82.7 games.

16.93/82.7 = 20.4%

So between the Main Game and the Hit 4 meter the game is up to 70.5%.

Now for the Hit 5 meter. When you catch 3 of 5 it puts 2 units in the Hit 5 Meter.

2/11.93 = 16.7645%.

When you catch 4 of 5 it puts 3 units into the Hit 5 Meter.

3/82.7 = 3.6276%

16.7645% + 3.6276% = 20.39%.

Hit the 5 out of 5, (freq. is 1551 rounded) and you get the money in the Hit 5 meter.

So now we have:

Main Game 50.1%
Hit 4 Meter = 20.4%
Hit 5 Meter = 20.39%

So we have a 90.89% game.

I'll show my strategy next....
