How it works

Cards meet sudoku

🃏

Draw a card

Flip from the deck to reveal your next play — a number and a suit. Each card belongs somewhere on the board.

🔷

Find its section

Each 3×3 box belongs to a suit. Hearts go in one box, clubs in another — the suit tells you where to look.

🧠

Apply sudoku logic

Use classic elimination: each number 1–9 appears once per row, column, and box. Find the one cell that works.

🏆

Fill the board

Place every card correctly to win. Wrong moves cost points — but you can still come back from a negative score.
