Notes

• Use Puzzles
Would you like a (free) Sudoku for a small, local, community newsletter. Or a monthly puzzle for your company's bulletin. Or a range of puzzles for your local newspaper? Or puzzles for a project of any size? KNS Puzzles was set up by my brother (Julian), specifically to provide commercial access to all of my content (current and old). If it involves BrainBashers puzzles, he will try his best to help. Take a look at my contact page for more information.

• Objective / Rules
- Complete the grid using all of the digits 1 to 9.
- When completed all of the sums must be correct.
- The sums are solved strictly left to right, top to bottom.
- The normal order of mathematical operations is ignored.
- For example 2 + 5 x 9 is calculated as (2 + 5) x 9 = 63.
- There are no ÷ 1 in the puzzle.
- There are no x 1 in the puzzle (although there might be 1 x).
- At no point will any calculation go below zero, or fractional.

• Help
Read the help/walkthrough page on MathemaGrids for a more detailed explanation and a walkthrough. Each sum turns green when the three entered digits satisfy that sum - however, that doesn't necessarily mean that the digits match the answer.

• Pencil Marks
What is a pencil mark? Pencil marks can help you keep track of your own thinking, simply enter more than one digit/letter into each square, just like you might do if you were using pen and paper. The size of the digits/letters is smaller when there is more than one digit/letter in a square. A square might contain more pencil mark digits/letters than can be shown.

• Checking
If you click 'Check' the system will check for incorrect squares. If 'Show mistakes when checking' is checked they will be marked in red.

• Uniqueness
Each puzzle has exactly one solution. If you think you've found another solution, then please double check the rules.
