An engaging mathematical puzzle that combines Sudoku logic with arithmetic challenges. Fill the grid with numbers so that they don't repeat in any row or column, and within the highlighted 'cages', the specified arithmetic operation (+, −, ×, ÷) must produce the indicated target number. The game offers grid sizes from 3×3 to 9×9 and three difficulty levels — from beginner to expert — making it enjoyable for both children and experienced number puzzle enthusiasts.
Open on Yandex GamesFill the grid with numbers so that each digit appears only once in every row and column. The grid is divided into "cages" marked by thick lines. In the corner of each cage, an arithmetic target and an operation sign (+, −, ×, ÷) are shown. The numbers inside the cage must produce that result: for example, "6+" means the sum of the numbers equals 6, "12×" means the product equals 12, "3÷" means the quotient of the larger number divided by the smaller equals 3, and "2−" means the difference between the larger and smaller numbers equals 2. A single-cell cage already contains its given number. The "Notes" button lets you place candidate marks in empty cells — handy for tricky combinations. Mistakes are highlighted, and three errors end the game. Use hints (earned by watching ads) to reveal the correct value in a selected cell. A timer tracks your solving time. The game begins with choosing a grid size (from 3×3 to 9×9) and a difficulty level.
