Amazing Sudoku

A 9x9 grid fills the board with 81 cells waiting for the missing digits. Rows cross columns, and each empty space has to take the right number from the set already shown around it. Amazing Sudoku includes four puzzle settings: easy, medium, hard, and expert. The difference lies in how many digits appear at the beginning. A timer runs during every round, and the board must be completed before the time runs out.

How to play?

Select a cell and enter the needed number to replace an empty spot on the grid. Draft mode adds tentative notes to individual squares when a final answer isn't ready yet. Use a hint if the board stalls. Check entered values to catch mistakes before they spread across the puzzle. Undo removes a recent move, and the full solution is available from the menu. Keyboard support includes arrow keys or W, A, S, and D for movement, number keys for input, F for draft mode, H for a hint, C for validation, U for undo, and Ctrl to view the shortcut list.
