DKM Sudoku Desktop comes with the same Classic style you have come to know, a Leonardo skin for that 15th century retro look, or the Bright skin if you would rather play with balls than digits.
Generate and solve unlimited, well-crafted Sudoku puzzles. DKM Sudoku Desktop builds on the popular DKM Sudoku Online puzzle generator and adds outstanding new features and a whole new look. Choose from four difficulty levels, different modes of input and the visual skin to suit your style. Utilize the many options to guide your learning and help you solve the trickiest puzzles all by logic alone. If you are tired of usual puzzle solving on your own, try challenging any of the six computer opponents to an exciting game of Sudoku Sniper. You and your opponent both solve the same puzzle simultaneously, with points awarded for correct entries and deducted for incorrect ones. Bonus points are also on offer.
DKM Sudoku Desktop takes the online version you have been playing on this website to a different level.
