Corylea, it worked on Windows 11 for me. If you post your system specs the community can try and figure out why

sailorbear510 aka Jason, not sure I agree with you on replayability, Jason. I have a half a dozen of these, and if this has a similar amount of levels, then I don't see a replayability issue. With this amount of levels, you'd probably have to play 24 hours to have a chance of completing the Newby level, and then you have the Professional level to complete. There are probably more than a 100 layouts here. Yes, it's the same layout on any 1 "deal", but that's so those who don't complete that deal successfully the 1st time can take another crack at it. More importantly, the cards change on every deal, so, like playing conventional solitaire, it's a different game every time. There are 10 deals to all the levels, which are likely more than 10. The ones I have have probably 20. So, that's maybe 200 deals. And, in each level, you have to collect a certain amount of the special cards available in the 10 deals. Say 55 out of a possible 60, to just pick some random but representable numbers. If you don't, you have to replay 1 or more deals to get more cards, until you reach the required number, or you can't move to the next level. Hence a replay on any 1 deal will always have the same layout, but, again, not the same cards. And, mostly, the deals in the later levels are significantly more difficult. But, even if you want a fresh layout every time, with this many deals, unless you play the whole game every day for the rest of your life - if you even could successfully - I can't imagine how you could remember each and every layout so completely that - even with different cards - it could get stale for you. The gameplay may get stale, but the layouts shouldn't - unless you have a photographic memory. And, if the game mechanics got stale for you, then you probably wouldn't care if the layouts were different or not. Also, the professional level doesn't allow you to stop the game with a less than satisfactory result on say, deal #5 in a level, and then replay that. If you got a zero on #5 when you quit, you'd have to go on to #6 when you resumed. If you completed the other 9 deals perfectly, and the 0 on #5 prevented you from completing the level, you'd have to go back to # 1 and start over again in professional, so the challenge and tension increases.

In fact, I recommend when you're playing in professional that you never quit with at least 1 more than half of the required cards in a deal. It can also be helpful to note the requirement on a level, and then keep track of your score as you go through each deal to have an idea when you can afford to do without a few cards on a particularly rough deal. To illustrate, if this is from the same developer as many of the others I have, there's a deal that resembles 3 Christmas candy canes that even the best card counters won't complete and is very difficult to get even half the cards on. And, since that deal has far and away the most required cards to collect - 18 - that I've seen, you'll probably have to replay and replay and replay even to get slightly over half. I think 12 or 14 is the best I've done - after many, many replays and a lot of luck, which leaves quite a few short of completing that level.
