🎮 How to Play Logic Grid Puzzles
Logic grid puzzles give you a set of clues about different categories of items. Using deduction, you must figure out which items belong together.
- Read all clues: Understand what information each clue provides.
- Mark definites: Use X for "no" and ✓ for "yes" in the grid.
- Use elimination: When you confirm a match, eliminate all other possibilities in that row and column.
- Cross-reference: Combine clues to deduce new information.
💡 Logic Grid Strategies
- Start with direct clues: "Alex is not the doctor" → immediately mark an X.
- Look for limiting clues: "The teacher lives in the red house" narrows down two categories at once.
- Process of elimination: When a row or column has all but one X, the remaining cell must be ✓.
- Re-read clues: As you fill in the grid, clues that seemed unhelpful earlier may now provide new information.
