in reply to implementing a scrabble-esque game on Termux III

Q2: Did you copy the dictionary file from Win to Linux without removing the \r's ?
That's one of the differences between the two.

Check your cache files, maybe delete and rebuild them.

I run on Linux (ArchLinux) so what I posted works there.

      This is the heart of finding a place to move. For a word to be a legal move, it must match one of the patterns in @pat. The (?<!\w) prevents putting the new word next to a preceding word, and the (?!\w) prevent putting the new word abutting a following word. The(*FAIL) forces the regex engine to try every possible place to find a match.

      Try 

      perl -le ' "abcd" =~ /.{2,}(?{print $&})(*FAIL)/ '

      and notice it prints out every substring with two or more characters.
