Sudoku: Classic & Killer Grids

Make Sudoku part of your day. Pick a classic grid, try the added challenge of Killer Sudoku, or reveal a picture one square at a time with Nonograms. There is a new classic challenge on the daily calendar, plus seasonal events with more levels to work through. Use a hint if you get stuck, switch between light, dark and sepia themes, and keep playing puzzles offline wherever you are. There is more than one way to take a puzzle break. Classic Sudoku is the familiar number grid; Killer Sudoku adds sum clues to think through; Nonograms reveal a picture as you work out which squares to fill. Pick whichever suits the time you have. The calendar gives you a reason to return each day, while the seasonal map offers a run of classic and Killer levels. If a grid proves tricky, hints help you find your next step. Settle in with a light, dark or sepia theme, and take your usual puzzles offline when you travel. Jot possible numbers into a cell as pencil notes. They update automatically as you fill in the grid.
