Math Crossword Puzzle

Math Crossword Puzzle is a challenging math puzzle where you have to solve a crossword by making sure that all additions and subtractions are valid.
There are two types of puzzles that can be used; the 5x5 puzzle and the 7x7 puzzle.
These puzzles can be played in different ways; you can choose the numbers that are used in the puzzle (1-10, 1-25 or 1-50) and the complexity (easy or hard).
In the easy level only the numbers after the = sign have to be filled in. This level is well suited for children.
In the hard level numbers are taken out randomly. It's a real challenge to solve these puzzles.
In the free version you can play 10 puzzles (for every number and complexity). After upgrading to the pro version, 250 puzzles will be available and the adds will be removed!
