Sudoku Companion 1.4.6

Sudoku Companion is an elegant Sudoku assistant for Mac.
What is Sudoku? It is a brainteaser coming from Japan, very popular in many countries around the world. There are scientific researches describing the mathematics behind Sudoku, and many teachers recommend it as improving logical thinking, but in the first place it is a very enjoyable and intelligent game.
There is only one very simple rule: Fill in the grid so that every column, every row and each of the nine 3 x 3 boxes contains all digits from 1 through 9. Sounds easy? Try it out!
The aim of Sudoku Companion is to make solving Sudoku puzzles more convenient. It is very Mac-like and it has all necessary and expected features: multiple undos, notes in each cell, every move is validated, you can save and load a puzzle or print it out and much, much more. Sudoku Companion has also an option that allows you to trace the remaining valid numbers for each cell, but be careful - it is a very powerful weapon so use it wisely. It can change simple puzzles into boring ones but at the same time it can help you to concentrate on the strategy when you are solving really difficult Sudokus.
Sudoku Companion wont solve anything for you, it would be a fun killer, but it will allow you to enjoy solving Sudokus on your Mac without paper, pencil and bottles of Tipp-Ex.
