Step back through your actions: Click , then select Autofill Notes. Notes representing possible numbers appear in empty squares, based on all filled squares at that moment — givens and your answers (even if incorrect). You can still add and delete notes manually. Using Autofill doesn’t affect stats or streaks.
Play with or without notes: Click , select Settings, then select Show Conflicts. When you enter a number that already appears more than once in a block, row or column, the squares’ bottom-right corners are marked with red triangles.
Mark incorrect answers as you enter them: Click , then select Check Square or Check Puzzle. A red slash indicates incorrect answers. Checking a square or puzzle doesn’t affect stats or streaks.
Identify a solvable square: Click , then select How to Play.
If you’d like a fresh start, you can clear a puzzle’s answers and reset the timer.
