Sudoku focus tips

If you keep losing your place halfway through a puzzle, give yourself a smaller task and a clear way to return to it. These suggestions organise a solving session; you can use whichever ones suit your routine.

Choose the session before the difficulty

Decide whether you want relaxed play or to study something unfamiliar. Select a comfortable level for a short break. For learning, allow yourself to pause and read an explanation. The difficulty guide describes the available choices.

Make the grid comfortable to read

Choose a view where you can distinguish notes from final digits. If you prefer paper, try one puzzle on a full sheet. Keep the tools you need nearby and put unrelated screens or notifications aside if they interrupt your session.

Give each pass a purpose

Pick one missing digit or one row, column or box to inspect. When you find a placement, check its three groups, update affected notes and then return to your pass. If you keep revisiting an unchanged area, move on and mark it for later.

Leave a restart note

Before a break, write down the puzzle's date and difficulty, where you were looking and what remains uncertain. “Check 7 in the middle-left box” is more useful than “stuck.” Keep that reminder separate from candidate notes inside the grid.

Restart with a check

When you return, reread your reminder and check the relevant entries before adding anything. If you find a duplicate or a cell with no candidates, use the error checklist. If the grid seems consistent, follow the stuck-puzzle guide.

Let a pause be a pause

You can stop without setting a finishing deadline. If timing makes the session less enjoyable, leave it out. The solving-time guide explains why comparisons need context.
