About this game

Tired of puzzle games that just give you the answer when you get stuck?

Welcome to a smarter way to play Calcudoku. Whether you are a seasoned veteran or a logic puzzle beginner, our math puzzle app doesn’t just show you where numbers go—it teaches you how to find them.

If you love classic Sudoku, Killer Sudoku, KenKen, or math crosswords, Calcudoku offers an intellectual step up that challenges your arithmetic and deduction skills.

--- THE SMART LOGIC HELPER ---

If you get stuck, our built-in Calcudoku helper analyzes your exact grid state and explains the logical next step. Instead of ruining the logic puzzle by solving the cell for you, the engine guides you through advanced grid strategies. You’ll learn how to cross-reference cages, update your number notes, and look for cell candidate reductions so you can solve the math matrix completely on your own.

--- KEY GAME FEATURES ---

• INTELLIGENT EXPLANATIONS: Step-by-step guidance focused on note-taking, elimination strategies, and candidate pruning. It’s the ultimate brain training tool.

• OPTIONAL AUTO NOTES: Start new games with notes in cells based on cage arithmetic.

• SMOOTH CELL NOTES: Rapidly input and edit candidate notes with an intuitive, fluid UI built for mobile screens.

• COMPLETE ARITHMETIC VARIETY: Choose logic grids featuring addition, subtraction, multiplication, and division loops.

• GRIDS FOR EVERY SKILL LEVEL: Play everything from quick 4x4 warmups to grueling, massive 9x9 math matrices.

• POLISHED INTERFACE: Full native dark mode support with crisp typography.

• OFFLINE MODE: Play anywhere without Wi-Fi.

Master the grid, elevate your deduction skills, and train your brain with a math game that actually makes you a better solver. Download Calcudoku today and start crunching cages!
