About CNN Sudoku

CNN Sudoku is the classic number puzzle listed on the CNN Games page, next to CNN's crosswords and other daily puzzles. Denda Games makes it. Its loader names it Sudoku (CNN), and it runs in any modern browser on desktop or phone.

The puzzle is the standard nine by nine grid, split into nine three by three boxes, with some cells filled in to start. You work out the missing digits so that every row, every column and every box holds the numbers one to nine exactly once. Each has one solution. There is one grid per day, the same for everyone, and a calendar icon in the top bar leads to earlier days.

Below the grid sit a number pad, an eraser and buttons for Notes, Undo and Hint. Notes let you pencil small candidate digits into a cell. Icons along the top open the rules, a restart, the calendar, your stats and the settings. It fits a phone.

Play is free. A short video ad can play inside the game frame before the grid appears, and it can usually be skipped after a few seconds.

It suits anyone who likes a calm logic puzzle with no time pressure, and readers who want a daily sudoku from a news site they already visit.

Tips

Scan for rows, columns or boxes that already have many digits, where only one number can fit a cell.
Pencil in the possible digits for tricky cells, then remove options as you place certain numbers.
Work the three by three boxes and the lines together, since a digit placed in one often resolves another.
Use Notes for cells with two or three options, and save Hint for when you are truly stuck.
