Cross Sum is a simple math puzzle, where the numbers 1 to 9 are placed in a 3 by 3 grid, with operators in between. You have to solve the 6equations – 3 horizontally, 3 vertically – matching the results at the right and at the bottom of the grid. There are some additional rules:

Calculate from left to right: 1 + 3 x 4 = 16, not 13
The first operator can be plus or minus, the second can be all four
The intermediate result and the end result have to be zero or greater
Only integer numbers (whole numbers) are allowed, no fractions

Cross Sum Standard lets you:

Create standard Cross Sum puzzles with numbers 1-9
Using the ‘standard’ operators for these puzzles – the first one can be plus or minus, the second one can be anything
Only whole numbers (integer numbers) are allowed
Customize the font, colors, line width and canvas color

For rebels amongst us, there’s also a version that breaks the rules: Use different numbers, negatives, fractions, or even use the regular math operator precedence, in Cross Sum Variations (see “Product Comparison” below).
