Grid Basics
📋 What it is
A logic grid lets you match items across categories by marking ✓ and ✗ where clues force them.
🗣️ Coach says
A logic-grid puzzle looks scary but it’s just bookkeeping. Each clue is a ✓ or a bunch of ✗s. Fill them in carefully and the answer appears — you never have to guess.
🧠 Memory hook
One ✓ in a row/column means ✗ for all the rest. A yes here forces a no everywhere else.
😂 Giggle
Why did the feedback peg feel so honest?
Because it always tells you exactly how close you got!
😲 Whoa!
A single ✓ can trigger a cascade of ✗s across the whole grid — one clue solving five squares at once.
✅ Quick check: You mark "Sam ✓ owns the dog." What can you mark in Sam’s row and the dog’s column?
Say your answer out loud first — then reveal.
✗ everywhere else in Sam’s row and the dog’s column — Sam owns nothing else, and nobody else owns the dog.
Each person↔pet is one-to-one, so a yes forces a no across the rest of that row and column.
