It's very easy to make a magic square if the length of a side is an odd number.

### Step 1:

Draw out your square (I'm doing a 5x5 square):

``` _ _ _ _ _
|_|_|_|_|_|
|_|_|_|_|_|
|_|_|_|_|_|
|_|_|_|_|_|
|_|_|_|_|_|
```

### Step 2:

Find the center space in the first row, and put the number '1' in it.

``` _ _ _ _ _
|_|_|1|_|_|
|_|_|_|_|_|
|_|_|_|_|_|
|_|_|_|_|_|
|_|_|_|_|_|
```

### Step 3:

Finish filling in the square by moving up and to the right from the last number you added. If you go off the edge, then just wrap around.

``` _ _ _ _ _
|_|_|1|_|_|
|_|_|_|_|_|
|_|_|_|_|_|
|_|_|_|_|_|
|_|_|_|2|_|
```

When you get to a point where the next space is already filled, instead of going up and to the right, drop a row, and then continue.

``` _ _ _ _ _
|_|_|1|_|_|
|_|5|_|_|_|
|4|6|_|_|_|
|_|_|_|_|3|
|_|_|_|2|_|
```

When you're finished, the magic square will work. Each row and column on a 5x5 equals 65.
