Sudoku 247

A fresh layout changes the look of classic number grids in Sudoku 247. Four puzzle settings shape the pace, from Easy boards for new players to a hard mode aimed at experienced Sudoku fans. A running clock stays on screen through each round. Support options are built in for stalled attempts, and score records tie directly to finishing time. The point total begins at a different value in each mode. Wrong entries add 15 seconds to the clock.

How to play?

Fill the grid with numbers under standard Sudoku rules. Place a digit only when it doesn't already appear in the same row, column, or square. Invalid placements are blocked before they land on the board. Use notes for harder deductions. The settings menu also includes animations, error checking, and instructions. Move through all four difficulty options at your own pace, then chase a faster record on completed boards.
