Sharpen your logic and math skills by solving Cross Math and Cross Compare puzzles! 

To solve Cross Math puzzles, fill in the blanks for each row and column to satisfy the equation. Each puzzle has a mix of addition, subtraction, multiplication, and division. They’re harder than they look!

For Cross Compare puzzles, fill in the blanks so that no number is used more than once in a row or column, and all inequalities are respected.

To help you out, pencil marks and undo/redo are available.
