Interlocking words, no clues: just four categories to guide you. Guess real words to reveal the letters.
Crux is a free daily word puzzle from Mind Loft — a clueless crossword. Eight hidden words (twelve in the Sunday Edition) interlock in a compact grid, and the only hints are four visible categories; working out which words belong to them is the puzzle.
Guess real words to reveal letters: dark tiles lock a letter into its square and every crossing, yellow tiles mean the letter belongs elsewhere in the word. The whole board shares one guess budget, and a single submit files each solved word under its category — a point per solve, a point per correct placement.
