Continuing from last week:

This is our cheat sheet so far:

One possible game state that can be reached from the start is the following:

Thanks to Bart Wright and S.A. for their input this week. Unfortunately, I’ve been busy with other stuff. To be more specific, I have discovered a truly remarkable idea for solving the problem of cheating in online chess tournaments. Unfortunately, this blog is not large enough to contain it. Besides, the tagline of the whole blog is “Spider Solitaire, the whole Spider Solitaire and nothing but the Spider Solitaire”, so I would also need to find some obscure connection to justify including this idea. On top of that, some of the comments failed the TL;DR test but the main gist seems to be “we can turn over new cards in Columns 1 and 6”.

S.A. gets bonus points for mentioning that we soon get to find out if Microsoft Solitaire allows scores to go into negative numbers, or whether the score remains at zero for the remainder of the game (and undo becomes free). I guess there is also the third option that the game terminates after 500 moves and we never get to find out if this game is winnable. Let’s hope it doesn’t come to that. But at least we have a “cliffhanger” which means Bart, S.A. and Sebastian are morally obliged to read the next few posts. Win-win for everybody 😊

Since we know the next deal is J6254A388K, it is relatively straightforward to determine the next unknown card in columns 1 and 6 starting from the above game state (NB: the next unknown card is determined by the cheat sheet, not the screenshot of the current game state).

Our luck is in: it is relatively straightforward to obtain a void in either Column 1 or Column 6 after dealing a row of ten cards. And yes, we have our first Nine 😊

It is not hard to see we have three guaranteed empty columns – so we should be able to determine the identity of almost every face down card. If you have played many games with undo, you are probably familiar with this pleasant situation.

**QUESTION**: What is the minimum guaranteed turnovers, starting from the above game state (score=109), playing with undo but not dealing any more rows from the stock?

BTW, in other news, Big Shiny Red Question Mark has been fully reinstated with all rights and privileges therein (thanks to Schistocerca Americana for the heads-up). But I’ve been told by a reliable source that BSRQM is still recovering from the mental scars of being Rick-Rolled. I guess there are things that 100,000,000,000 rupees can’t buy.
