Hints

The basic premise of this SuDoku assistant is to help you solve the puzzle.
There are many levels of help.
The simplest is letting you note what values a cell can have, in a way that doesn't involve lots of erasing!
You can also tell SuDoku to do some simple tasks to help identify possible values (such as find permissible values, fill in singles, and finding unique values).
Although these tasks are straightforward (they are notational rather than logical), they can be repetitive... hence subject to mistake when done by hand

However, iteratively choosing these simple tasks and updating will automatically solve most puzzles!

Your challenge: solve the puzzle using the minimum amount of help from the SuDoku assistant!

Instructions:

  1. Reset to original puzzle
  2. Start a new puzzle
