🧠 Strategies to Win Sudoku Competitions

Want an advantage?

Here are strategies top online competitors use.

1. Start With a Full Grid Scan

Before placing numbers:

Quickly scan all rows, columns, and boxes
Identify easy singles
Mark candidates early

This reduces mistakes during adrenaline-filled races.

2. Use Pencil Marks Aggressively

In competition, clarity = speed.

Good pencil-mark habits:

Auto-fill candidates early
Eliminate candidates instantly
Keep marks clean and updated
Check pairs and triples quickly

Mistakes come from unclear grids—not lack of skill.

3. Solve in Layers

Top solvers rarely get stuck because they:

Sweep the grid
Update candidates
Sweep again
Narrow down possibilities

This systematic approach is faster than jumping around randomly.

4. Don't Guess Early

Guessing leads to:

Mistakes
Backtracking
Lost time

Use logic until the very end.

Sudoku is 50% logic, 50% mental control.

Before the race:

Take a deep breath
Relax your eyes
Focus on structure, not speed

A calm player beats a panicked fast player.
