@Adám the crossword clues are input → output mappings, and the user has to fill out the APL train/dfn that fulfills this

the solutions to the clues will be chosen such that they will have different solutions at similar lengths, so the player will have to think of unconventional ways to fit other primitives into solving a clue

@KritixiLithos The Vector Journal used to run such crosswords.

oh nice, is there somewhere you can link to?

ah found them google.co.uk/search?q=site%3Aarchive.vector.org.uk+crossword and ddg duckduckgo.com/…

I'd love to see them converted to Unicode and rerendered.

DDG links to a different view, which does render but incorrectly so, archive.vector.org.uk/art10007650

Ah, the HTML is so old the browser doesn't render it right!

uses APL2741, which according to apl385.com/fonts/index.htm, "Historic interest only. This was hand digitised as a PostScript Type-3 font from an original 2741 golf-ball salvaged from an IBM selectric typewriter. Looks good on paper, but poor on screen as it is lightweight and italic. The hinting is rudimentary and even with ClearType it is hard to read!"
