Read Our Unique Sudoku Scoring System Carefully before starting

    Remember, every wrong input or mistake will set the Streak Count to Zero(0).
  • For Every correct number input:
    • 1. Easy: (10 + Streak Count * 5)
    • 2. Medium: (15 + Streak Count * 10)
    • 3. Hard: (20 + Streak Count * 15)

▦ 5 Must-Know Strategies before you start

From a daily player who used to avoid Medium puzzles-and now finishes them fast:

  • The Quick Scan

    "Start with rows/columns/grids with the fewest missing digits, let's say just 2-3 numbers—these often reveal quick placements"
    Why it works: Medium puzzles hide 1-2 obvious moves to help you start solving.

  • Spotting Hidden Pairs (The Silent Clue)

    "Two numbers that can only go in two cells?? Mark them with notes(Pencil Marks)—they’ll unlock other placements"
    Pro tip: Circle hidden pairs lightly to avoid confusion.

  • The Elimination Game

    "For tricky numbers (like 6 or 9), ask: Where can this not go?"
    Example: If 6 can’t be in 7/9 cells of a row, it must be in the remaining two.

  • Use Pencil Marking Smartly

    Here is when you really need to use the 'Notes' feature:

    • Write numbers normally when you are 90% sure
    • Two or three possible candidates
    Avoid: Over-marking—Medium Sudoku Puzzles shouldn’t need endless notes.
