Sudoku

16 guides
  1. How to solve sudoku faster: speed without guessing

    7 min

    Speed comes from scanning order and pattern recognition, not from rushing. Scan by digit, pencil-mark only when you stall, learn the handful of techniques you actually hit, never guess, and race the clock until it is automatic.

  2. The hardest sudoku puzzles, and how to actually solve them

    7 min

    What makes a sudoku hard is not more blanks, it is the techniques it forces. X-wings, swordfish, XY-wings, and chains. What separates expert and extreme puzzles, and the method for cracking the ones that look impossible.

  3. Sudoku XYZ-wing: the trivalue pivot variant of Y-wing

    5 min

    Y-wing's slightly bigger cousin. A trivalue pivot {x,y,z} plus two bivalue wings {x,z} and {y,z}, all sharing the digit z. Any cell that sees all three loses z as a candidate. Worked example, when it appears.

  4. Sudoku unique rectangle: the uniqueness-based elimination

    7 min

    Four cells in a rectangle across two rows, two columns, and two boxes, all sharing the same two candidates. If left alone, the puzzle would have two solutions, but a well-formed sudoku has exactly one. Use that to force an elimination.

  5. Sudoku naked pairs and triples: the cell-set elimination

    6 min

    When two cells in a unit share the same two candidates, those two digits are locked into that pair. Everywhere else in the unit can drop both digits. The most-used intermediate technique after pointing pairs.

  6. Sudoku skyscraper: the cousin of X-wing for short-strong patterns

    5 min

    The skyscraper sits between X-wing and the harder fish patterns. Two strong links on a single digit, ending in cells of different heights, and the elimination that falls out. Worked example included.

  7. How Melio Sudoku scoring works

    4 min

    Score = base × time factor × mistake factor × hint factor. Here's exactly what each one does, why the formula is shaped this way, and how to push a 1,000-point Expert solve toward 2,000.

  8. Sudoku Y-wing (XY-wing): the bivalue trick that breaks expert puzzles

    6 min

    The Y-wing is shaped like a chain, not a rectangle. Three bivalue cells, three candidate values, one elimination. Here's the pattern, why it works, and how it plays with the X-wing.

  9. What is an X-wing in sudoku? The trick that breaks expert puzzles

    6 min

    The X-wing is the gateway from 'I solve hard sudokus by scanning' to 'I solve expert sudokus by reasoning.' Here's how to spot it, why it works, and what to do once you find one.

  10. Sudoku pointing pairs and triples: the easiest intermediate technique

    5 min

    The first technique you learn after scanning. Pointing pairs unlock half the puzzles labeled 'medium' and a third of those labeled 'hard.' Worked examples, the precise rule, and the box-line cousin.

  11. How to host a sudoku tournament with friends

    7 min

    Bracket structure, difficulty calibration, the rematch flow, and how to use spectator URLs as a casting feed. A practical walkthrough for running a 4-16 player sudoku event in one evening.

  12. How to build a daily puzzle habit (and why it works)

    7 min

    The psychology of streaks, why 5 minutes of puzzling beats an hour of scrolling, the research on puzzles and cognitive aging, and a 30-day starter plan.

  13. Sudoku swordfish and jellyfish: the advanced fish patterns

    8 min

    The X-wing extended. Swordfish (3 rows) and jellyfish (4 rows) catch eliminations that X-wing can't. Step-by-step with examples, when to look, what to look for.

  14. How to play sudoku with friends: race, co-op, and spectator modes

    8 min

    Sudoku used to be a solo activity. Melio makes it multiplayer: race the same puzzle, solve one together, or stream a match for an audience. Here's how each mode works.

  15. Sudoku tips for beginners: your first 10 puzzles

    7 min

    How to actually start solving sudoku if you've never finished one. Where to scan first, what pencil marks are for, when you're stuck, and when to move up a difficulty.
