Play Sudoku on your PC without using pen and paper. Just Sudoku 1.0 is a free game with lots of different puzzles to solve. The sudoku puzzles are divided into five different levels of difficulty. The aim of sudoku is to enter the digits from 1 to 9 in a grid with 81 cells without repeating them in rows, columns and regions. Just Sudoku 1.0 has an easy to use point-and-click interface and can easily be installed and uninstalled. It is a simple game, but unbelievable addictive.
The number picking system is unique. Ease to pick a number without losing track of which cell you wanted it for, like some others I've tried!
Cons
I cannot figure out how to correct a mistake by deleting just that number; delete erases ALL that you've put in! ALSO - the contrasting background between the blank cells & the pre-entered numbers is TOO EXTREME. They overshadow the 4 grid lines marking the 9 cubes, making it hard to scan in the right areas.
