CalcuDokuNotes

  • Objective / Rules
    - You have to complete the grid such that every row and column contains the numbers 1 to 6.
    - Each row and column contains each number only once.
    - A cage clue tells you answer after the cage values have undergone the specified mathematical operation.
    - e.g. 2÷ means that when the digits in the cage are divided the answer is 2.
    - A digit may appear more than once in a cage (which is different to Killer Sudoku).
    - The Hard puzzles can be quite hard and often require the more advanced Sudoku techniques.

  • Help
    Read the help/walkthrough page on CalcuDoku for a more detailed explanation.

  • Online Calculator
    We have provided an online calculator which might help you.

  • Keyboard Usage [only when your cursor is in the grid]
    Note: not all options work on all browsers.
    A = auto-pencil marks. (or click the check box below the puzzle)
    CTRL + arrows = move around the grid.
    SHIFT + number = highlight all squares with that number [SHIFT+0 to clear]

  • 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. There are two types of error checked for:
    1. A single number that isn't the same as the solution.
    2. Multiple numbers that don't contain the solution number.

  • Uniqueness
    Each puzzle has exactly one solution, which can be found using logic alone and no guesses are ever required. If you think you've found another solution, then please double check the rules. If you still think you've found another solution, then please email us and we'll try to help.
