Sudoku

Fill in every empty cell so that each row, each column, and each 3×3 box contains all the digits 1 through 9 — with no repeats.

Tap a cell to select it, then tap a number on the pad (or press a key on your keyboard) to fill it in. Wrong entries turn red. Use Check to validate the board at any time.

Everyone in Singapore gets the same daily puzzle. Choose a difficulty that suits you — easy has more clues, expert leaves the fewest.
