How to Solve a Magic Square
Start with the line that is already complete: add its numbers to find the magic sum. Then look for a row, column, or diagonal with only one empty cell, and subtract the numbers you know from the magic sum to find the missing one. Repeat until the square is full, and check that every line adds up to the same total.
How do the levels work?
The first level uses the numbers 1 to 9, each exactly once, with a magic sum of 15. The next levels use larger numbers, up to 30 and then up to 100, which makes the additions and subtractions more challenging. Every square can be solved step by step, without guessing.
Tips for magic squares
- Find the magic sum first, using the complete line.
- Always look for a line with just one missing number.
- In a 3x3 magic square, the center number is one third of the magic sum.
- Check your work by adding every row, column, and diagonal.
