My project Luna's Father has been put on hold in order to allow myself to put my brain to rest when it comes to that and to focus on something else for awhile. This will eventually work out better for Luna's father. 

House of Cards is just a collection of solitaire based games, released under an open source license (GPL3).

At this moment only King's Corners and Pyramid work properly, but more games are planned. I have made a start with the support of Spider. As soon as Spider works, I may already put up an (alpha) release, while I work on the not yet operational games. 

If you wish to contribute, well, at this moment the game can work with the English, Dutch, Italian, German and French languages, but if you wanna add a language I don't know, then let me know and I'll tell you how to create an extra language file. It's just a plain text file in .ini format, so it should be easy to workout.
One note the language must mainly use the ROMAN alphabet. I am willing to add a few characters unique to a language, like the ß in German for example, but a full character-set will be undoable.

If you wanna design an extra deck for me to use, hey, then you are very very welcome to do so. The more the merrier. 

If you can make your design to fit onto this template, we're cool. Now you are free to put the symbols K♠ or Q♥ or J🔶 or A♣ on that, but if you don't I can script the game to put those in (the big advantage is that this will cause the letters to adapt based on the chosen language).

Oh, and if you have a cool backside for cards, hey they are welcome too, and basically the same template applies.
Yes, I am interested in having more card games added than currently listed. Of course, I need to learn (and be able to understand) the rules.
