Massive word-grouping puzzles — find which words belong together! Inspired by Thomas Colthurst's incredible 2025 puzzle. If you haven't played that, you should play it first. Unlike that puzzle, these are largely generated by LLM — the model brainstorms categories and items, then a review agent checks for quality, cross-category consistency, and solvability before the LLM-agent approves the puzzle, which is finally lightly reviewed and edited by a human.
