The Sudoku Challenge goes far beyond the traditional offerings, with thousands of puzzles to solve. Beginners can use the feature that checks whether each number is correct as they enter in into the grid, to help them get a feel for the puzzles. Each member of the household can create their own profile and save their high scores to see who is the sharpest of them all!

In the midst of such innovations, one feature will be instantly recognisable to all experienced Sudoku solvers - the ability to jot down tiny numbers in the game squares, narrowing down the possible solutions for each cell. With difficulty levels ranging from 'simple' to the innocently-named 'hard', gamers will be pleased to know that there's always an electronic eraser on hand as well! And for those who don't have laptops, the program will print out puzzles for the gamer to solve whilst on the move.
