Logic Grid Puzzles

How this challenge works

Deduction Practice turns written clues into two interactive matching grids. Mark impossible pairs with × and confirmed pairs with ✓ until every person has exactly one item from each category.

• Read all clues before making a firm match.
• Use × to eliminate and ✓ to confirm.
• Every current fixture was independently verified to have exactly one solution; the library now contains 40 verified source structures at each of four difficulty levels, with deterministic story variants in ordinary Practice.
