I was going to investigate different implementations of basic solitaire and maybe turn it into a post but then I opened PysolFC¹ and it played the hardest background music track I have ever heard, so I've decided to stop the journey here because nothing could possibly top this.

1. Opened it on my Windows machine anyway, as opening it on my Mac causes the entire device to crash (so, be warned).

my Windows PC just crashed and I have no idea if it was because I had PysolFC open or if it was the 800+ Firefox tabs I also happened to have open at the time (as I do at most times). be careful out there, gamers
