  • My Mom complains there are too many ads in the Windows Solitaire, so I'm trying to make my own :) Still a little buggy here and there, but fully playable. Card design by CaglarAlperen (CC0).
    Looks good. You might also want to send PySolFC to your mom so she has something to play while waiting for your version to be finished. Source: almost 4 years ago

    Have you looked at PySolFC? It has all the card game and while it's not a clone of Windows Solitaire, it looks good, has the auto drop and card animations when you win a game. I find it to be really good. Source: over 4 years ago
