This is stuff related to playing cards. Either writting rules that I have played for posterity, or rules I made up and wanted to write somewhere even if I never tried them out.
Those are games meant to be played with a french-suited (aka "standard") playing cards.
President, a game that I played a lot in college, putting our local/house rules here for posterity. Comes with a variant I made and actually played with people.
3 Piles, original game that I actually played against a human. Most fleshed-out rules of my original games.
The badly-named "fantasy deck" is a custom playing card game I had in mind for world building purposes (which I haven't actually used yet). It's inspired by Mahjong tiles somewhat.
It's a 60 cards deck, with 4 suits of 15 cards each. The ranks are Blank (acting as 0 or jokers), numbers from 1 to 12, Flower, and Dragon. The suits are Star (blue), Leaf (green), Sword (red), and Coin (yellow).
The flowers and dragons are specific to each suit, supposedly referencing actual and/or mythical flowers and dragons in the fantasy world.
Star dragon is benevolent, representing curiosity, wisdom, and similar stuff.
Leaf dragon is benevolent too, representing nature, growth, that kind of stuff.
Sword dragon is malevolent, representing war, violence, conflict, and other similar things.
Coin dragon is also malevolent, representing greed, selfishness, manipulation, that kind of things.
Multiple cultures in that fantasy world would skew and twist some of these interpretations in accordance to their values, but I haven't really given much thought to that part.
Here are some games I made up to play with it. Note those aren't fully fleshed out and also I've never actually played any of them with humans.
Read about it on its own page here, explaining its content isn't very compact.
Here are some games I made up to play with it. These also aren't fully fleshed out and also weren't played with actual humans.
Annarius, a 2-players trick taking game where you try to win differently in each of the 4 seasons. The scoring would need some tuning, and it could also use actual playtesting.
Propheta, a trick taking game where you try to predict specific events related to the tricks to score. The scoring would need some tuning, and it could also use actual playtesting.
