SuDoku by Mastersoft is finally available after an extensive public beta! Features of Mastersoft SuDoku include over a million built-in puzzles, a puzzle solver to help you figure out other puzzles (like the newspaper one), a scoring system where additional features and puzzles will become available as you become a SuDoku Master and more.
What is SuDoku? It is a puzzle game where a 9×9 grid must be filled in with numbers. On each row, column and regions (smaller 3×3 subgrids), the numbers 1 through 9 can only show up once. Logic rather than math will help you solve the puzzles.
Mastersoft SuDoku is now available for $14.95 USD.
