## What is CrossMath?

Ready to put your math skills and deductive logic to the ultimate test?

Welcome to CrossMath: DogDoku Puzzle – the premier math crossword puzzle game designed to sharpen your mental arithmetic, boost problem-solving speed, and deliver satisfying brain workouts every single day!

MASTER THE ART OF CROSSMATH
CrossMath takes classic crossword grids and supercharges them with numbers and math operations. Instead of reading word clues, every row and column forms an interlocking math equation.

• Balance the Equations: Use addition, subtraction, multiplication, and division to complete each line.
• Follow Order of Operations: Keep BODMAS/PEMDAS rules in mind—multiplication and division always calculate first!
• Crossword Intersections: Every number you place impacts both horizontal and vertical equations simultaneously.
• Deduce, Don't Guess: Work through the board step by step with pure logic and strategic planning.

DOGDOKU MODE
Want a fun change of pace between math sessions? Jump right into DogDoku whenever you want—fully unlocked and available from day one!

• Spatial Deduction Fun: A delightful fusion of Sudoku and grid-based logic.
• Place the Puppies: Figure out where each cute dog belongs across distinct colored sectors.
• Keep Personal Space: Ensure dogs never touch each other—not even diagonally!
• Switch Seamlessly: Alternate between numbers and puppies with just one tap on the home screen.

KEY HIGHLIGHTS
• Comprehensive Mental Workout: Strengthen calculation speed, focus, and logical reasoning with every grid.
• Multiple Difficulty Tiers: Start on Easy to warm up, then conquer Medium, Hard, and Expert boards built for calculation masters.
• Daily Challenges: Fresh math puzzles every day to maintain your streak and keep your brain sharp.
• Clean & Minimalist Design: Clutter-free interface built for fast, smooth, and distraction-free tap-and-play input.
