Sudoku Practice Plan: 4-Week Skill Builder

One puzzle a day is great. A clear plan for which puzzles and which skills? That’s how you actually get better.

This practice plan is for anyone who wants to move from “I can finish some puzzles” to “I understand what I’m doing.” It assumes you know the basic rules and can finish Easy puzzles, but feel shaky on Medium and above.

The structure is simple: four weeks, each with a focus. You’ll use a mix of the daily puzzle, printable PDFs, and a small set of strategies from the strategy library.

Week 1 – Build a Solid Easy Foundation

Goal: Finish Easy puzzles calmly, with almost no mistakes.

If Easy puzzles still feel slow at the end of the week, stay here for another week – speed comes from comfort.

Week 2 – Graduate to Medium with Pairs

Goal: Become comfortable finishing Medium puzzles without guessing.

  • Daily: 1 Medium puzzle from Daily Sudoku or Medium printables, plus an Easy puzzle as a warm‑up if you like.
  • Focus techniques: add naked pairs and hidden pairs to your singles toolkit.
  • Drill: once or twice this week, scan a finished puzzle and mark where pairs could have helped you move faster.

Expect Medium puzzles to feel slow at first. That’s fine – the point is to recognise where singles run out and pairs take over.

Week 3 – Learn Box-Line and Pointing Moves

Goal: Unlock eliminations that open up stuck grids.

  • Daily: alternate between Medium and Hard puzzles using Hard printables or your preferred difficulty in the app.
  • Focus techniques: pointing pairs / box‑line reduction and the general idea of “locked candidates”.
  • Rescue routine: when you’re stuck, run this sequence: singles → pairs → pointing/box‑line → stop and re‑scan instead of guessing.

By the end of this week you should be able to look at a crowded box or row and quickly tell if there’s a locked candidate hiding there.

Week 4 – Add a First “Hard” Pattern

Goal: Touch advanced logic without drowning in it.

  • Daily: 1 puzzle at the hardest level you can almost finish (Hard or Expert), plus one easier puzzle for confidence.
  • Focus techniques: pick just one from X‑Wing or XY‑Wing and look for it deliberately.
  • Review: after each hard puzzle, spend 2–3 minutes reviewing where you stalled and whether a pattern or pair would have moved you forward.

You do not have to master X‑Wing or XY‑Wing in a week. The win here is simply recognising that these patterns exist and spotting one or two in the wild.

Keeping the Habit Going

After four weeks, you can loop the plan with higher difficulties, or focus on a single week’s structure that fits your current level. What matters most is consistency:
