Controls

  • Click a cell to select it, then type or tap a number to place it.
  • Use note mode (pencil marks) to list candidates for a cell without committing.
  • On touch devices, tap a cell then tap the number pad.

Tips & strategy

  • Start with the rows, columns or boxes that already have the most given numbers.
  • Use pencil marks for candidates, then scan for "singles" where only one number fits.
  • Look for naked pairs: if two cells in a unit share the same two candidates, neither can go elsewhere in that unit.
  • When stuck, re-scan each unit for a number that can only sit in one cell.

Daily Killer Sudoku FAQ

Do I need to guess?

No. A well-formed puzzle is solvable by pure logic. If you resort to guessing, re-check your pencil marks — a deduction was missed.

What are pencil marks for?

They track which numbers could still fit a cell, so you can spot when a candidate is eliminated elsewhere and becomes a forced placement.
