How to Get Better at Sudoku: A Simple Practice Plan

Learn one technique at a time

Trying to absorb every strategy at once leads to nothing sticking. Pick a single technique, such as hidden singles, and use only that for a few days. Force yourself to find every hidden single before making any other move. Once it feels natural, add the next technique on top.

Play at the right level

Growth happens just above your comfort zone. If a level feels effortless, you are practicing skills you already have. If it feels crushing, you will get frustrated and quit. Play the level that makes you think hard but still lets you finish, and step up when it starts to feel routine.

Use notes deliberately

Strong solvers lean on notes to see the whole board. Practice filling candidates accurately and reading the patterns they reveal. With smart cleanup keeping your notes honest, you can focus on the logic instead of the bookkeeping.

Review your stuck moments

When you get stuck and finally find the move, pause and notice what you missed. Was it a hidden single you skipped, or a pair you did not spot? Naming the gap teaches your eye to catch it faster next time. Every hard moment is a lesson if you look at it.

Build a daily habit

A short puzzle every day beats a long session once a week, because skills come from repetition spread over time. The Daily Challenge is a perfect anchor. One puzzle, same for everyone, fresh each day. Keep a streak going and your progress becomes visible.

A four week plan

1. Week one: master scanning and crosshatching on Easy boards.
2. Week two: drill naked and hidden singles on Medium boards.
3. Week three: learn naked pairs and pointing pairs on Hard boards.
4. Week four: try the X-Wing and take on an Extreme puzzle.

Stick with it and you will feel the difference within a month. Start today with one puzzle in Shapedoku, choose a single technique to focus on, and let the habit do the rest.
