Each card's output is another card's input.

Each card has a function on it, each function is written in 4 languages: c, go, python, js. The game starts with the list [0, 0, 0, 0]. You must play either the same function in a different language, or any function in the same language as the previous card. Each card takes a list and return a list, and there are punk0, punk1, punk2, punk3 cards that print what you should do depending on the appropriate index of the list. For example if the list gets to [0, -2, 1, 3] and you play punk1(x), which operates on index 1 of the list, in this case having value -2, you must play 2 more valid cards, or draw from the deck.

There is also an easy mode: play as if increment/decrement, rotate_left/rotate_right punk0/punk1/punk2/punk3 are the same function.

This is how example round looks:

I worked on this game mainly to teach my daughter that knowing many languages is not very important, what you need to know is how things work, also what they represent, and especially, how the computer sees them. Also to start building intuition about rotating and manipulating pieces of memory. If you are a parent teaching your kid, and is exploring more tools to help you, I made few other card games:

This is possibly the 30th version of the game, and its really fun (I think), we printed and tried many versions and I want to thank my friends who helped me test it: ronen, peter, maarten, angel, mattias, tarek, deo, evanji, melore, aymeric and many others who I annoyed with playing the boring versions :D .. here are some of the failed attempts:

PS: No LLM was used for the cards, but I did use some ChatGPT to help me rephrase the rules, since english is not my native language and I do struggle with expressing my ideas especially when the space is so limited.
