Description
If you love Sudoku, Binary puzzles, or Takuzu, get ready for a fresh mental workout. DUO takes the classic logic grid concept and refines it into a sleek, modern experience designed to test your deductive reasoning and spatial intelligence.

HOW IT WORKS
Every move is a balance. Your goal is to fill the grid with symbols (Hearts, Spades, Diamonds, Clubs) while obeying three strict rules. No math is required: just pure logic.

GAME FEATURES
🧠 Infinite Logic Challenges
From quick 4x4 warm-ups to massive 12x12 Expert grids, there is a level for every mood. Whether you have 2 minutes or 2 hours, DUO keeps your brain sharp.

⚔️ Classic & Quad Modes
Classic: Play with 2 symbols for a Zen binary experience.
Quad Mode: Step up the difficulty with 4 symbols for an expert-level challenge.

📈 Deep Statistics & Streaks
Track your brain training journey with detailed stats. Monitor your Win Rate, visualize your Daily Streak on the calendar, and race against your own "Best Time" across all difficulty levels.

✏️ Smart Solving Tools
Don't just guess, deduce! Use Notes to visualize possibilities before you commit. Stuck on a hard pattern? Use smart Hints to break through or Error Highlighting to catch mistakes instantly.

🎨 Customize Your Experience
Make the game yours with unlockable themes and board styles.
Themes: Switch between Sunset, Forest, and our beautiful Dark Mode.
Styles: Choose from Minimal, Neon, or Dot-style grids.
Controls: Toggle "Select & Place" for speed or classic tapping for precision.

Why play DUO?
It’s more than just a game; it’s a gym for your brain. Perfect for fans of grid puzzles, crosswords, and Sudoku who want a clean, minimalist experience without the clutter.
