Sudoku with Hints

Across one collection, Sudoku with Hints gathers several puzzle grids and rule variations. The classic layout uses a 9x9 board with 81 cells. Number puzzles appear alongside letter grids, diagonal versions, and layouts with extra zones. Five difficulty settings change how many symbols are already placed before the round begins. Fewer filled cells leave more work on the board.

How to play?

Place a number or letter into an empty cell. A symbol may appear only once in its row, once in its column, and once in each 3x3 block. The same rule applies across the included variants. Hint mode adds candidate symbols inside the cells when a position feels uncertain. If a cell shows 3 and 7, only those two values fit there. Progress through more of the grid on your own. The hint marks grow more precise around the middle of the puzzle.
