Lock Solitaire has me hesitant to autostack, the first time I did while ever card was stacked in what I could've sworn was a clean order it trapped me with a one 13 of a locked suit. Which I imagine is something to do with the ordering of the stack, but it was admittedly a kind of sour way to lose that attempt and essentially makes me consider the button a death sentence. I don't know that there's necessarily a fix, rather just wanted to note that the button is kind of a bad time in that mode.
Still a fun mode though, also done 10 wins on Tap and Eldritch, Eldritch got a little weird because I found it easier to yolo the matches and occasionally I just get stuck with like a 12 and no appropriate matching cards. But that's to be expected of such a playstyle tbh.
