UnlimitedNothing here counts towards your streak or the day’s board.
Fill every empty cell so no digit repeats in a row, a column or a box.
Clock0:00
25 cells still empty.
Today is the hard kind. No square and no digit is down to one on its own, so a pair of squares has to be worked out together. The small number under each digit in the bar is how many of it are still to place.

Stopping early still scores, on the cells you got right.

Fill every empty cell so no digit repeats in a row, a column or a box.
- Tap an empty cell and choose a digit from 1 to 6.The digits that came printed on the grid are fixed, and you can never write over one.
- Clear a cell and try a different digit whenever you change your mind.Nothing is marked right or wrong while you play, so a wrong digit costs you nothing until you finish.
- Fill all thirty-six cells to finish.There is only ever one answer, and the clock is your score.

What the words mean
- Box:
- one of the six heavy-outlined blocks, three cells across and two down. Each holds 1 to 6 once, the same as a row does
- Given:
- a number that came printed on the grid. You cannot change it, and you never need to
- Naked single:
- a cell where only one digit can possibly fit, because the other five are already in its row, column or box
- Hidden single:
- a digit with only one place left in a row, column or box, even though that cell looks like it could take other digits too
- Past the singles:
- neither of the two above cracks it open on its own, so you will need to hold two possibilities in mind at once
- Par:
- a good time for today's grid, not a great one. Beating it puts you well up the table
