Super Sudoku: 3 Levels of Difficulty

A full 9x9 grid waits to be completed in Super Sudoku: 3 Levels of Difficulty. Empty squares sit between preset numbers, and the number of filled cells changes with easy, medium, and hard modes. Classic Sudoku rules stay in place across all three settings. Each puzzle uses 81 spaces, with rows, columns, and every 3x3 box requiring different digits from 1 to 9.

How to play?

Place numbers into the blank cells until the board is complete. Check each row against the matching column, then verify the 3x3 box before adding another digit. Repeated numbers break the solution and carry the mistake across the rest of the puzzle. More preset digits give easier placement options. Fewer givens leave larger gaps to work through. Move from easy to medium after finishing a full board, then try hard once the rules and number positions feel natural.
