Hi all, along the theme of educational games I have found an online game which uses a simple numbering scheme to make for a seriously challenging game. The principle of the game are simple. You have a 9x9 matrix which comprises 3 3x3 cubes. The object is to fill in numbers between 1-9 inclusive in all the spaces. However the catch is no 9 long row must contain the same number twice and no 3x3 cube must contain the same number. The best way to see this is to head over to
http://www.websudoku.com/ and try it out. Its not for the swiftess exactly but u do get ranked according to time against all others that play it. I will include some screen shots for those that don't wish to venture to the site along with my scores in the easiest and hardest (evil) levels of difficulty.
