1. Setup: A grid of words is created — words along the rows and columns. Each intersection is a coordinate (like A1, B3).
2. Draw Cards: Each player draws coordinate cards from a shared pile. These are secret — don't show them!
3. Give a Clue: When you're ready, give a single word clue that connects the two words at your card's intersection.
4. Guess: The other players get one guess to place your card on the correct grid cell.
5. Score: Correct guesses place the card. Wrong guesses discard it. Try to fill the whole grid!

Clue Rules: One word only. Can't share a root with either code word. Can't reuse any clue.
