Daily Sudoku X

A fresh diagonal grid waits each day in Daily Sudoku X. Weekday-based puzzle sets stretch far ahead, with a new 9x9 number board tied to each day and four modes ranging from easy to pro. The rules stay the same across all of them. Fill the empty cells with digits from 1 to 9. Every row allows each number once. The same rule applies to every column, each 3x3 box, and both main diagonals. Given digits are already placed in part of the grid. Easy boards include many of them. Pro boards leave far fewer clues on the board.

How to play?

Work from the placed numbers first. Complete small 3x3 boxes from the clues already printed in nearby cells, then extend those placements across the board. Examine one cell at a time. Check its row, its column, and the two crossing diagonals before entering a digit. Use the checker when a placement feels doubtful. Switch the weekday to load a different arrangement and continue daily Sudoku puzzle practice with another board.
