Solved

Explanation

Reveal the reasoning
  1. Begin with the cross-category links that lock two items together. Here, Clue 1 connect Mat Color, Session Time.
  2. Clue 1 links Coral (Mat Color) with 10 AM (Session Time), so those two items must belong to the same participant.
  3. Next, apply the elimination clues to shrink rows and columns before committing to any checks.
  4. Clue 5 rules out 8 AM and 10 AM (Session Time) for Uma, which forces the remaining options.
  5. Clue 6 rules out Teal and Coral (Mat Color) for Vic, which forces the remaining options.
  6. Clue 7 rules out 8 AM and 11 AM (Session Time) for Wren, which forces the remaining options.
  7. Whenever a participant has only one remaining option in a category, mark it as a check and cross out the rest (one-to-one). Keep propagating until every participant has exactly one match in each category.
