btw, you might also like https://punkx.org/overflow/ which is a buffer overflow riscv assembly board game, or depending on your kid's level you can also play snakes and ladders with gotos https://punkx.org/overflow/build/snakes-and-ladders.pdf
Also if you have kids, I would recommend you print https://punkx.org/panic/ which has amazing pranks that fit in one poker card (e.g. randomly hitting backspace or space every 30 seconds, or pressing W randomly if minecraft is open)
I am donating a lot of the decks to teachers and schools, so if you are interested send me an email.
PS: I am in London for 1 more week, so if you order decks now the shipping will be delayed, but I will make sure I add 1-2 extra decks in the package because of it.
PPS: the unix pipes expansion deck is all about process substitution, but I don't think its useful for kids, though I think it contains nice puzzles
