Sudoku (Fox News)

Sudoku is one of the free daily games on Fox News's games page, alongside a daily crossword, a mini crossword, 5 Across and a word search. It runs in a player from Playgent, the company behind the page's other puzzle embeds.

The puzzle is the familiar one: fill the 9x9 grid so every row, column and 3x3 box holds the digits 1 to 9 once. You tap an empty cell and choose a number from the pad below the grid. A pencil button switches to notes for candidates, there are undo and erase buttons, and a small supply of hints helps when you are stuck. The grid opens at Hard, and a difficulty menu switches between five levels: Mini, Easy, Medium, Hard and Extreme. A calendar opens earlier puzzles. A timer runs while you solve.

It is free with ads and needs no account. It suits sudoku players who want a dependable daily grid on a news site they already read.
