If you love Sudoku but are looking for a deeper challenge, or if you simply enjoy games that give your brain a real workout, Calcudoku is the ultimate logic puzzle. It combines the grid-filling deduction of Sudoku with simple arithmetic, creating a deeply satisfying balance of mental math, strategy, and problem-solving. Whether you want to sharpen your focus, keep your mind agile during a quick break, or master complex logical deduction, Calcudoku offers endless replayability for beginners and puzzle veterans alike. --- WHAT IS CALCUDOKU? --- Also known as Mathdoku or KenKen®, Calcudoku challenges you to solve a grid using logic and arithmetic: • Grid: Fill an N x N grid so that every row and column contains the numbers 1 through N exactly once without repeating. You choose the grid size to solve, anywhere from a 3x3 to a 9x9. • Cages: Outlined groups of cells (cages) each display a target number and an arithmetic operator. • Math: The numbers in each cage must combine using its operator (+, −, ×, ÷) to hit the target. Numbers can repeat within a cage as long as they stay in different rows and columns. It’s the ultimate combination of mental math, pattern recognition, and pure deduction. --- THE SMART DIFFERENTIATOR --- Many puzzle apps ruin the fun when you get stuck by simply filling in a random cell for you when requesting help. Our app takes a different approach: it teaches you how to solve it. If you hit a wall, our built-in helper analyzes your exact grid state and explains the logical next step. The engine guides you through genuine deduction strategies—showing you how to cross-reference overlapping cages, prune cell candidates, and leverage your notes so you can solve the grid completely on your own. --- KEY GAME FEATURES --- • Intelligent Explanations: Step-by-step guidance focused on note-taking, elimination strategies, and candidate pruning rather than giving away answers. • Optional Auto-Notes: The settings tab provides the option to jump into a puzzle with the initial candidate notes based on cage arithmetic. Skip the mundane and get right to the logic! • Smooth Input: Rapidly input answers and edit candidate notes with an intuitive, fluid UI built for mobile screens. • Complete Arithmetic Variety: Play grids featuring addition, subtraction, multiplication, and division. • All Skill Levels: Progress from quick 3x3 warmups to grueling 9x9 logic grids. • Polished Interface: Full native dark mode support, crisp typography, and seamless offline play - no Wi-Fi required. Master the grid, elevate your deduction skills, and train your brain with a game that actually makes you a better solver.
