It inspired a weekend project. I always liked that you could swap the card backs in OG FreeCell and play with different "themed" decks, so I vibecoded something a little more modern. I got carried away and added a roguelite mode too (yeah I know how "Roguelite FreeCell" sounds). Anyway, it's free to play on the web, no ads: [https://freecellworlds.com/]
Basically a 1992 rogue-lite where each room is a different solitaire game. eg: front parlor == clock solitaire, first bedroom == regular solitaire, upstairs is blocked by freecell, etc...

It's a fairly rich concept, you have a ton of different gameplay bound together by a very loose plot/quest mechanisms (eg: blue key == blue door ; boss == win 2 games of solitaire).
Definitely worth sharing if you've got some solitaire fans in your life!
