Sudoku: Classic & Killer Grids

One grid or a whole afternoon: find the Sudoku challenge that fits your day. Play classic Sudoku at your level, work through the extra arithmetic of Killer Sudoku, or switch to a Nonogram picture puzzle. The calendar brings a new classic puzzle each day. Seasonal events add more classic and Killer levels to explore. Hints are there when you need a hand, and light, dark, and sepia themes let you choose a comfortable look. Take your favorite puzzles offline. Choose how to play: • Classic Sudoku: fill the grid using logic and find a challenge that matches your mood. • Killer Sudoku: combine number placement with sums for a different kind of solve. • Nonogram: use the clues to reveal a picture, square by square. Come back for the daily calendar puzzle or follow a seasonal event map when you want a series of levels. A hint can help you move forward without leaving the puzzle behind. Switch between light, dark, and sepia themes to make the screen feel right for you. Whether you're at home or on the move, you can keep solving offline. Pencil in possible numbers for each cell. Your notes update automatically as you fill in the grid.
