At first I thought I hit the replay button instead of the play button! B-2-B

Why were you slower the second time around?

I guess I started to recognize the game. Then I said, nah. Then it really looked the same. I solved it differently the second time also!

If you replay a game you played it streak mode, it still shows up in the logs as 'streak', so not saying it wasn't legitimately the same game twice in a row, but it would show up the same way if it was a replay. Anyway, the odds would be about 1 in 32000, assuming Denny's algorithm is sufficiently random :P. Given how many games are played everyday it probably happens reasonably frequently...though the odds of it being noticed are a little slimmer :P.

It wasn't a replay. BackToBack's winnable 13x0 streak is 20 and the RHP shows 20 wins since the last loss and that includes the repeated deal which wouldn't add to the streak if it was a replay.

good detective work roo...oh and since it's winnable, I guess it's a little higher than 1 in 32000, closer to 1 in 30,000...still low though. :P

Forget theoretical probability and statistics.In reality,seems to happen more often.Game 13x0 3397 10 dealt at 8.06 PM and 8.09 PM.

It happens more often with winnablesolitaire.com ...dunno why, but I noted it a couple years ago, and it keeps happening. Not B-2-B every time, but in a little rotation with several other deals, sort of as if the random-generator gets caught in a loop.

This seems to be happening more than it used to. I just got the same game twice in the current WWC, winnable 10x1, level 6, with a different game between the two. I know El Guapo posted a screen shot of his duplication on Nov. 11, and I know there was a more recent discussion than this thread, but I couldn't find it. Here's mine. See the top (last) game, and third from last. (And sorry, I'm not proficient at "Paint". I'm rather bad at it, obviously.)

This nicely exemplifies the (at times noticeable) mechanical nature of randomness that is *supposedly* achieved, vice (again even here, supposedly) *true* randomness--a la nuclear beta particle emission. Possibilities here, I admit. I'm not familiar enough with code writing to go deeply into the greater or lesser likelihoods, though I probably completed identical deals in WS around 1/2 of 1% of the time. I think I remember reading that 70% of random WS deals are winnable. A surprisingly high number, at least to myself. J.J.C. Smart wrote some interesting stuff on this type of thought, nicely melding some physics with his expertise in logic.

To me now, a few 10x1s apart. I'll provide the utile Cs-137 if someone has the mechanical bent, available time, necessary capital/resources, and rather varied and advanced skill set needed for one to create such a (supposedly) more-random number generator. Of course, then again, who could possibly care about such superfluous stuff, except to banter on about its legitimate philosophical underpinnings, i.e. fatalism vs. hard-determinism vs soft-determinism vs. libertarianism? Colloquially speaking then, who controls the Fates?

Interesting post, and aside from the obvious that Denny controls the universe, including statistics. (It's a little-known fact that "standard deviation" was almost named "the Denny deviation", but he quashed that idea because of the unsavory connotations some would construe.) So....what I've always wanted to know....is who/how/why is beta decay (and other nuclear decays) so 'random', yet so statistically predictable? I mean, what causes a particular atom/nucleus to decide one day/second/nanosecond, "Hey, I think I've had enough of being this isotope; I'm gonna split myself up." If the answer to that is in quantum mechanics, I've never encountered it - or at least don't remember it...

To me the beauty is in the musings that are spurred on by it. I believe it really can get one to question what truly *is* completely random--if there be such a thing. I find it then giving strengthening credence to a quote of Disraeli's I deeply respect: "To be conscious that you are ignorant is a great step to knowledge." As an aside, I apologize for the goofy facetiousness of some of my previous post. Just games...on a gaming site...
