Spin Poker and Super Times Play

#1

Anyone know the difference in variance for spin poker versus super times play?

My wife and I always stay at South Point now because of their great variety of games. Our favorite two games are the 9/6jacks 25 cent spin poker and the 25cent 8/5BP STP five play which are both a lot of fun to play. I had worried mostly about spin poker hitting the bankroll hard, but lately STP seems worse.

I figured that the STP at $7.50 per hand wouldn't suck the money up as fast as $11.25 hand on spin poker, but I'm beginning to think we're better off playing mostly spin poker. Any insight on this is appreciated. Thanks.

STP increases the return by 0.278%, and increases the standard
deviation by 51 percent. You square the standard deviation to get the
variance, so:

For 9/6 JoB,
Regular: 99.54% return, 19.51 variance
STP: 99.82% return, 44.50 variance
Spin Poker: 99.54% return, 53.00 variance

Incidentally, a game of blackjack has a variance of about 1.30.

Correct me if I'm mistaken, but the increase of 51% (which I see cited on the wizardofodds.com website) is in reference to variance increase over the base game before taking into account the multiline game format.

As such, your value of 44.5 isn't the full measure of STP play variance and not comparable as you suggest. Further, with the added component of multiline covariance, there would be unique values for 3-play, 5-play and 10-play.

(Finally, I won't presume to suggest that the variance math you present in your posts isn't your own, independent work. However, to the extent that you may be relying upon similar information presented by Michael Shackleford (wizardofodds.com) he is due credit. Such credit, or other relevant background, also assists others in better appreciating the info you graciously take the time to convey.

It is from the Wizard, yes. I mentioned him earlier and then forgot to
continue doing so.

Thanks to both of you for the info. It seems STP would have at least as high a variance as spin poker and probably higher on the five play machines that we play.
