A Q-Less game solver.

Julia (v1.8.0+ recommended) and the JLD2 package.

Run julia qsolve.jl LETTERS [WORDLIST], where LETTERS are the letters rolled and WORDLIST is a file containing a (newline-separated) list of acceptable words; for instance, julia qsolve.jl adhjmorrtuvx Routledge-5K.txt.

If WORDLIST is omitted, the default file used is NWL2020.txt (the 2020 NASPA Word List). For easier rolls, the file Routledge-5K.txt (the 2010 Routledge list of the 5000 most frequent words in contemporary American English) typically yields several solutions and is much quicker to search with.

• Are there any unsolvable rolls?
  • Yes; for instance, fgjlmmnnnoot is unsolvable (using the NASPA list).
• What percentage of rolls are unsolvable?
  • In a trial consisting of 5000 random rolls, only 31 (0.62%) were unsolvable using the NASPA list; in a trial consisting of 1000 random rolls, 472 (47.2%) were unsolvable using the Routledge list. This suggests that the vast majority of rolls are solvable and that around half are easily solvable.
