Sudoku

Number logic in its purest form.

Fill the 9×9 grid so every row, column and box contains the numbers 1 to 9.

How to play

• Every row, column and 3×3 box must contain the numbers 1 to 9 with no repeats.
• Select a cell and type a number with your keyboard or the number pad.
• Turn on notes mode (N key) to jot down candidates in a cell.
• If you get stuck, buy a hint with Pupicoins (5 to 20 depending on difficulty, H key): it fills in a cell, but with hints your time doesn’t count toward your best.
• If you lose on mistakes after correctly filling at least 25% of the empty cells, you still get some of the Pupicoins.

Sudoku Duel

Both players solve the same sudoku at the same time. In time mode, the first to finish wins; in points mode, whoever gets each cell right first.
