HardMath: Cross Math Puzzle

🧮 HardMath is a cross math number puzzle: a crossword-style grid where every row and column must form a correct equation.Place number tiles into the empty cells and make every line add up — literally. Add, subtract, multiply and divide your way across the board. The rules take seconds to learn, but the harder grids will really make you think. Every puzzle has exactly one logical solution, so it's pure deduction from start to finish. No guessing required, ever.✦ How ads work in HardMath
