Quick Sudoku

Speed shapes every grid in Quick Sudoku. A standard 9x9 board fills the screen, but the pressure comes from the clock, not from altered rules. Easy mode gives 30 minutes. Medium cuts that to 20. Hard leaves only 10, pushing this Sudoku puzzle toward players who already know the classic format and want faster completion times. Final scoring uses time spent on the board, rewarding quicker finishes.

How to play?

Choose a timer setting, then place digits from 1 through 9 into the empty cells across all 81 spaces. Rows block repeated numbers. Columns follow the same restriction, and each mini-square must also hold every digit only once. Pencil marks fit above a cell when a choice isn't certain yet. Erasing a number removes a bad pick. Replacing a digit updates the grid immediately.
