"When You're Stuck, It Quietly Gets Easier" — Reactive Crossword Construction from FDG 2026
One piece today: "Dynamic Crossword Difficulty via Reactive Puzzle Construction" by Colan Biemer and Seth Cooper (Northeastern University), presented at the Procedural Content Generation Workshop co-located with Foundations of Digital Games 2026 (FDG '26), held August 10–13, 2026 in Copenhagen. Unlike a conventional crossword where every square is fixed before play, this paper proposes and evaluates a "reactive" construction method that quietly lowers difficulty when a solver gets stuck and adds easier intersecting "hint" words. Across simulated Beginner-to-Expert personas, the reactive-with-hints variant produced the largest drops in both solve time and surprisal (a difficulty measure). The authors themselves note the method isn't suited for players who want a genuine challenge.
