Talk:Klondike (solitaire)

Different ways of playing

How many ways are there to make Klondike as easy or difficult as you like?? Here they are. You are free to add more if you can:

Redeals:

You can set not to allow redealing, or to allow 1, 2, 3, or 4 redeals, or to redeal as often as you like. Setting this option to a low number means a harder game.

Draw:

You can set this to 1, 2, or 3 cards at a time. Setting this option to a high number means a harder game.

Filling Empty Columns:

You can select this to any card, only a king, only a card from the stock as long as the stock isn't empty, and no card at all. The last of these would mean a really difficult game.

Suit discrimination:

Equal suit, equal color, unequal color, and no suit discrimination. This gives 16 variants because there are 2 suit discriminations that are not necessarily the same, how the foundations are built up and how the columns are built down. The easiest of these is obviously no suit discrimination at all.

Pulling from foundations:

Microsoft Solitaire allows pulling cards (even aces) back down from the foundations to the piles. This increases the odds of winning considerably, and might make the game more enjoyable (personal opinion), as some interesting strategies are made possible. I haven't seen this mentioned in any rule set yet, not even in Microsoft's help text.

Klondike (solitaire)

Moved from Klondike solitaire to be in line with other solitaire game article names. -- Netoholic 04:47, 15 Jul 2004 (UTC)

The "(5.0)" on the picture is unnecessary - the version number in the about box refers to the version of windows [5.0 is windows 2000] - solitaire itself doesn't have a version number [and, as far as i know, the only changes that have ever been made to it are to make it 32-bit and to load card images from an external library]

Yep. Just look at the status bar--still Windows 3.x style! --Jason McHuff 02:19, 1 October 2005 (UTC)

Canfield, Demon and Klondike

The Penguin Book of Patience has this division differently. According to them, "Klondike" is the name for either Demon (see Canfield (solitaire)), or Canfield (see Klondike (solitaire)). Should something be done about that? Mysha (nl)

Odds of Winning

Any deck that can be solved in Thoughtful Solitare can be solved in regular solitaire as well: simply make all the right choices.

• Perhaps the question should be rephrased as, "given perfect use of limited knowledge, what percentage of decks will be solved"
• Then it seems that the percentage of decks that can be solved in thoughtful solitaire would be an upper bound on the percentage of decks that would be solved using perfect strategy in standard solitaire.
• Lower limit would be set by the best computer player devised so far, or the long run average for the best human player.

I don't understand why it's so difficult to compute the possible number of winning games of solitate. It would take time, yes, but I'm just shocked no one has done it. RobertM525 05:09, 6 June 2006 (UTC)

There's about 2 billion possible deals; if it ever is found out, I'm sure it won't just be one person doing all the work. 130.184.237.233 17:47, 22 June 2006 (UTC)

Not one person, of course. But a computer should be able to run through all of them given enough time... RobertM525 11:20, 23 June 2006 (UTC)

I remember reading about someone who kept records of his own games of Klondike and came up with an average of one game in 30. (This is for the one-card-at-a-time-with-no-redeal version.) This seems about right to me. Kostaki mou 01:18, 9 February 2007 (UTC)

At the moment the article states that: "A modified version of the game called "Thoughtful Solitaire" has a known solution strategy that works 70% of the time but requires significant computing power. This solution strategy does not solve every deck that is solvable, but is about twice as good as the best human players." Does it refer to games where redeals are allowed or not? Because with redeals it's easy to reach 70% of wins anyway. Here is a screenshots of solitaire statistics after 1000 games with 88% wins (redeal and undo allowed) File:Http://upload.wikimedia.org/wikipedia/en/f/f3/Solitairestatistics.jpg

Actually, the basic premise here is false - not all solvable Thoughtful games are solvable in Klondike. In Thoughtful it is possible that the initial deal will include stacks topped by a downward sequence of cards in alternating colors. That sequence could then be moved off as a unit in Thoughtful, but not in Klondike, because in Klondike all but the top card would be face down. What people are trying to get at is the solvability when you know what the face down cards are, which is not the same as the solvability when you deal the cards face up. JanDWolter (talk) 21:52, 4 January 2014 (UTC)

I realise your comment is almost a decade old, but you've misunderstood what Thoughtful Klondike is. Thoughtful Klondike is not simply dealing all the cards face-up. It's exactly the same as normal Klondike, except that you know what each face-down card is before you turn it over. In your example, the alternating sequence from the initial deal cannot be moved as a unit in Thoughtful Klondike, because all but one of the cards are face down. Knowing the value of the face-down cards lets you strategize, but it doesn't let you move them, since only face-up cards can be moved. I think the article now makes that quite clear; probably it didn't, back in 2014. Dricherby (talk) 10:47, 12 September 2023 (UTC)

Merge from Wes Cherry

I claim that the Wes Cherry article should redirect to Klondike (solitaire)#Computerized versions, with any content unique to his article moved over, for what I think are fairly obvious reasons. There's no evidence that he's notable for anything other than developing Windows Solitaire, and his article says little or nothing about him except that he did so. Stellmach 21:56, 2 September 2006 (UTC)

Okay, this merge seems to be entirely uncontroversial. Going ahead. -Stellmach 13:23, 8 September 2006 (UTC)

Demerge from Wes Cherry

The information on Wes Cherry has been removed except for a link. Either this information should be restored, or the Wes Cherry article should be demerged. I would favour demerger because it is the more accident-resistent way. 86.140.97.102 10:14, 31 May 2007 (UTC)

"Most Played" assertion

Since computer games in general do not keep any kind of tracking information about how much time has been spent playing them, it seems as though the assertion that Klonidke has been the most commonly played one, while an appealing notion, will always be impossible to verify. -Stellmach 14:01, 6 September 2006 (UTC)

We can't do much about the data, but it seems like it should be easy to find one or more sources that make that claim. Seems more like a citation issue than an accuracy one, though it would be a good idea to add a comment similar to yours afterwards. -FunnyMan 05:03, 13 September 2006 (UTC)

I removed the assertion since it just can't be proved. — Hex (❝?!❞) 23:55, 5 October 2006 (UTC)

I've added three sources that assert it is "most popular". While it is debatable whether or not those assertions can be proved as correct, it's not our job to decide what is proven and what isn't. It's a common assertion that the Solitaire shipped with windows is the most popular game on a personal computer/handheld - one that is reflected in popular culture and the media. Hence, finding sources is not an issue. Icemotoboy (talk) 22:28, 25 February 2009 (UTC)

Maxcards?

What's "Maxcards", as referred to in the rules section? If it's the game referred to at maxcards.co.uk, I think we can do without this reference. Rojomoke 11:22, 8 February 2007 (UTC)

Windows version

Shouldn't we mention the Windows version a bit more? It's surely the most widely played PC as well as Windows game of all time and some would say is a significant drain on human labour in offices Nil Einne 23:31, 23 August 2007 (UTC)

scoring

I would like to see a scoring section that explains how the score is computed. in the windows version there are two different types of scoring and I think it would be interesting to know the difference.--Movesandpepper (talk) 17:41, 27 March 2008 (UTC)

On Windows Solitaire, the scoring is as follows:

• Moving a new card to a table pile 5 points
• Turning over a card 5 points
• Moving a card to a base pile 10 points
• Removing a card from a base pile -15 points
• Turning the deck over -100 points for one card draw
• Turning the deck over -20 points for three card draw after the third rotation
• Undo command undoes the score on Vista, -3 points previous versions
• In timed games, for each 5 seconds -2 points
• In timed games there is also a time-dependent bonus of around 4000 to 6000 points on completion.

My Vista Home Premium version has an error that gives 10 points for moving the aces between bases. I noted it in the article and had it removed when someone else found their version did not have the error. My version also does not grant 5 points for turning a card over when moving an ace to the base on the same move. Could anyone verify the differences on their versions -- 129.101.34.186

The second mode is Vegas Scoring (which I believe is actually used in some casinos). You pay $52 for each game and receive $5 for each card on the base piles when you have exhausted the deck once – so 11 cards home is a win. --217.134.77.95 (talk) 19:54, 30 March 2008 (UTC)

Klondike/Thoughtful difference

I admit that this constitutes original research, but as far as I can tell, there is a difference between Klondike and Thoughtful which causes the odds of winning to be different. The difference is when the reversed card at the top of a pile of reversed cards is the number higher than and the opposite colour to the card at the bottom of the pile on top of it, those playing thoughtful will be able to see that the two cards can be used as a run of 2 (or more) cards, whereas those playing Klondike will have to flip over the reversed card before they can be treated as a run. Is this a genuine difference? If so, will this actually cause a different in the odds? If these questions can't be adequately answered, I don't think that we can actually say that Thoughtful and Klondike have the same chances of being able to be won.Labrat256 02:14, 13 January 2010 (UTC) —Preceding unsigned comment added by Labrat256 (talk • contribs)

You've misunderstood how Thoughtful works. Thoughtful just means that you know the values of the face-down cards. They're still face-down, and they can't be moved until you turn them face-up as in normal Klondike. Knowing their values means that you can strategize, because you know the effect of a move before you make it. But it doesn't allow you to make any moves that you couldn't make in ordinary Klondike. The article now makes this quite clear IMO, but probably it was less clear when you wrote your comment. Dricherby (talk) 10:51, 12 September 2023 (UTC)

History?

When was Klondike created, how long has people played this particular solitaire? It predates the computer solitaire, doesn't it? Swimsuit Zipper (talk) 11:48, 29 November 2013 (UTC)

Where does the name come from?

Where does the name Klondike come from for this form of solitaire? — Preceding unsigned comment added by 80.193.189.151 (talk) 16:47, 27 April 2015 (UTC)

I also came here to this article to try and find the answer to this question, as I just installed Solitaire on Windows 10 and it was the first time I've come across the name Klondike for the game. Irrelevant background information: I was first introduced to the game as being called Patience, long before I first played a computerised version of the game (which incidentally was also called Patience) on an Acorn Archimedes in the early 1990s. I first came across the name Solitaire years later on a Windows 95 machine. Obviously, I'm not disputing the name; I'm just curious. --Beeurd (talk) 18:39, 5 September 2015 (UTC)

Odds of winning definitions

In the Odds of winning section of the article, four outcomes are claimed, but only three are defined: Theoretically winnable, playable and unplayable. Is the fourth outcome "Games won?"

Number of possible hands

206.248.63.215 recently wrote that there are 8 x 10^67 or 52! possible number of hands instead of "7,000 trillion". I got rid of his rambling about the Big Bang but kept the number for now, because it seems to make sense (although there is no source and it is technically original research). Highly Ridiculous (talk) 16:46, 1 July 2016 (UTC)

In actuality, the number of meaningfully unique names would be less, as there would be functionally no difference if you swapped all spades for clubs or all hearts for diamonds, or all reds for blacks. I haven't done the math to see what that would drop it down to though. Tristan (talk) 17:59, 10 July 2018 (UTC)

Error in image caption?

A lost game of Klondike. The stock is shown at the upper-left. The upper section of the Tableau shows downturned cards, and the lower section shows the upturned cards. Except the 2♥, no cards can be moved.

This image and caption is in the "Probability of winning" section. Can't the seven of spades also be moved, onto the eight of hearts (carrying the six of diamonds with it)? Herostratus (talk) 02:21, 19 December 2018 (UTC)

Yes it certainly can be moved. IMHO it even seems playable, for one can move the 5♣ in the stock (it's the 13th card from right) onto the 6♦ and then move the 4♥ with 3♠ to it, in this way a downturned card will be freed. But I don't know if one can win this game afterwards. --WhitePhosphorus (talk) 14:41, 7 February 2019 (UTC)

Thoughtful Solitaire is defined to be draw three, in which case none of the available stock cards (Qd, 9c, Kc, Kd, 9h, 6s) are movable. I've added a note to that effect. Arcorann (talk) 01:09, 29 February 2020 (UTC)

History and name

I've tweaked the history and name information in the light of better, albeit no doubt still imperfect, information. Arnold is incorrect to say that Canfield is a misnomer for Klondike; it is the traditional English name for the game, although that tradition is waning in the face of computer game competition. It is true though that in America, Canfield might be perceived as a misnomer, since it is the name of another game. Parlett is likely to be right about this as he is a card game historian rather than a card game compiler like Arnold.

There is more work to be done though. I am suspicious about the game appearing at the time of the gold rush because I can find no record of "Klondike" before 1849. However, games called Demon, Triangle, Fascination and Canfield, names sometimes given as synonyms for Klondike, are recorded in the early 20th century and may be its antecedents. However, I have yet to establish whether they were played to the same rules. The trouble is that card game compilers often don't check their facts and frequently describe the origin of games with apparent certainty when in fact they are talking utter drivel. Among the more laughable myths is the century-old one that Bierspiel is a German card game of the Rams family. There is absolutely no evidence for that in German sources whatsoever, unsurprising really because Bierspiel just means "drinking game". Bermicourt (talk) 19:24, 12 October 2020 (UTC)

Editorializing about the inexplicability of the popularity of the game in the lead?

Is it really necessary to provide Parlett's musing on this fact here? Jyamine (talk) 17:34, 24 April 2023 (UTC)

Recent edits

Two recent edits by an anonymous editor removed David Parlett's assessment of Klondike, one with the comment "Parlett's remark is highly opinionated and should not be presented as fact. Maybe people like a challenge?" Leaving aside that the second sentence implies Parlett is right anyway, he is one of the world's leading gaming experts and a consultant on the subject to film producers wanting authenticity. He has also penned one of the most comprehensive books on patience and solitaire ever written. So his views carry weight. And they are hardly extreme: Klondike "offers one of the lowest success rates of any patience". This is not only evident to anyone who plays solitaire card games, but is corroborated by American card game experts Morehead and Mott-Smith who assess its success rate at 1 in 30. So I have reverted the edits concerned. Bermicourt (talk) 08:37, 8 October 2023 (UTC)

My primary objection is to quoting Parlett's sensational language which presumes that there is some obvious contradiction between a game's difficulty and popularity. As you will see above, I'm not the only one to raise the concern. 2601:642:4600:3F80:D905:A44F:AB76:D886 (talk) 14:39, 8 October 2023 (UTC)

The way Wikipedia works is that you are welcome to make a 'bold' edit, but if it is reverted, you should discuss it on the talk page (here) until a consensus is reached. Repeatedly reinstating your bold edit could be seen as WP:EDITWARRING which is likely to lead to a ban, the original text being restored and then you will be unable to participate in the debate. So please restore the original for now and then we can move forward. Bermicourt (talk) 14:45, 8 October 2023 (UTC)

Okay, I see the issue here. Parlett, Morehead, Mott-Smith, Arnold, various American Hoyles and other card game authors who describe the game as difficult and the odds as 1 in 30, are talking about the classic version in which cards are properly shuffled (randomised), there is only one pass through the stock and no worrying back (albeit some authors acknowledge easier options and give different odds for them).

Meanwhile the article describes 5 versions of Klondike based on how the stock is dealt without pointing out, crucially, that this results in different levels of challenge ranging from easy (deal 1 card at a time, unlimited passes) to difficult (deal 3 at a time, 1 pass only). Computer versions such as MS Klondike make life even easier by also allowing worrying back from foundations to columns and offering varying levels of difficulty in which, at the lower levels, the cards are not randomised and so the game will succeed more often than not. No wonder Parlett's remarks seem at odds with our experience of the game!

This can be resolved. The article should be amended, using appropriate sources, to point out the range of difficulty/level of challenge resulting from different ways of dealing the stock and the comments of the experts should suitably qualified by making it clear which version of the game they are actually referring to. Bermicourt (talk) 17:11, 9 October 2023 (UTC)

The impact of varying rules on the probabilities is confirmed by vegassolitaire.com thus: "The odds of winning with Klondike depend on what version of Solitaire (Klondike) you play. There are many variations in rules which all have their influence on the outcome and odds. The following rules/factors have a significant impact on the odds of winning Solitaire:

• How many times you are allowed to go through the deck
• How many cards you are allowed to turn over at a time from the pile (draw one or draw 3)
• The game strategy (to finish all cards or to play a minimum of 11 cards to the Foundation)
• If rules allow, “Worry Back,” where you can play cards back from the Foundation to the Tableau..." See Vegas Solitaire Odds.

Vegas Solitaire is of course simply Klondike with Richard Canfield's alleged system of paying $52 for the pack and winning $5 for every card on the foundations, albeit often attributed to the different game of Demon/Canfield. Bermicourt (talk) 08:27, 10 October 2023 (UTC)

Future of section on "Probability of winning"

The section entitled "Probability of winning" is highly problematic. For a start it is not comparing like with like. It opens by quoting the "1 in 30" probability that we now know refers to the classic form of Klondike where the stock is dealt singly and there is one pass with no other privileges. It then describes "Thoughtful Klondike" which does not equate to any real version of the game because the computer knows the location of all the cards from the start. It wrongly claims this is the only difference, but it also allows limitless and repeated undo moves to solve the game, something that is not normally part of the game, but which ave been introduced into computer simulations geared to making it easier to win (and hence presumably more marketable). No wonder the computer can win "Thoughtful Klondike" 82% of the time, but that is of no relevance to real Klondike where peeking at all the cards would be tantamount to cheating. Thus the section is highly misleading and either needs to be rewritten to clarify this and cut down or deleted: it takes up far too much space for a theoretical analysis of a variant with different rules that is tangential to the article topic and not playable in practice.
