CageMath combines a Sudoku-style puzzle game with math symbols. Just like Sudoku, place numbers into the grid, where each number can only appear once in a column or a row. A CageMath grid is also sectioned into heavy-outlined "cages" that each have a smaller "cage-answer" and "cage-operator" in the corner. The numbers within that cage have to equal the cage-answer using the cage-operator. Some examples: √ 49 (What's the square root of 49?) 6- (Which two numbers can you subtract to give you 6?) 896x (Which 4 numbers can you multiply to result in 896?) CageMath is the only math-infused Sudoku game that tests your addition, subtraction, multiplication, division and square root skills! Features include: - UNLIMITED, UNIQUE games at various different grid sizes - Lifeline/hint button to reveal answers when you're stuck - Highlighter/note feature to support noting multiple numbers in one square - Game clock - Highscore tracker Note: Optimized for iPhone 5, 5s, 6s, 6 Plus, 6s Plus, iPad, iPad Retina, iPad Pro, iPad Air, iPad Air 2, iPad Retina, iPad 2 and all newer devices.
