Unix Pipes is a "play once" game, just so you can try some ideas, then try them out on the computer.

I used to randomly set HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon Shell to cmd.exe on my daughter's laptop so she can run programs from there, e.g. go the discord directory and start discord from there.

Then I made unix pipes just to help her with https://overthewire.org/wargames/bandit/ and so we can discuss how do you make "programs that do not know how they will be used", e.g. the programmer of "sort" does not know how it will be used, and you can create ridiculous pipe chains with the cards, just for fun.

Of course I made other random tasks, e.g. we take a random book and we start "catting" and "grepping" it

Most of the games i made on https://punkx.org are like that, i am just trying to teach her something and i need a bit of physical help to "get out of the computer"

The only real card game is http://punkx.org/punk0 which is like uno with state and I play it often with friends, and https://punkx.org/overflow/ which is super intense depending who you play with.
