## Notes

Objective / Rules
Complete the grid such that every row, every column, and every 3 x 3 block contains the digits from 1 to 9.
Every cage has a little clue in the corner, and digits in each cage must add to the clue.
A digit cannot appear more than once in a cage.

Help
Read the help page on Killer Sudoku for a more detailed explanation and a walkthrough.

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.

Usage
Note: only when supported by your computer / device / browser / etc (and only when your cursor is in the grid).
a = auto-pencil marks (or click the 'pencil' button).
p = show a pinned square.
CTRL + arrows = move around the grid.
SHIFT + digit = highlight all squares with that digit [SHIFT + 0 to clear].

Checking
If you click 'check' the system will check for single-digit squares that don't match the answer. You have to select 'Show mistakes' to see the mistakes.

Uniqueness
Every BrainBashers puzzle has exactly one correct answer, which can be found using logic and deduction alone, and no guesses are ever required. If you think that you have found another answer, then please check the rules carefully for a reason the other answer isn't allowed.

Combinations
