About this app

Developer Description

Sudoku without notes, train working memory while you play.

No notes, no hints, no shortcuts—just you, the grid, and your mind.
Mental Sudoku N-back removes common aids like candidate marking, highlights, and instant error checks, leaving only the raw challenge of solving in your head.

This approach is slower than standard Sudoku, but that’s the point. It encourages you to:

Hold numbers in memory instead of writing them down

Spot logical patterns without visual clues

Think several moves ahead before committing

You’ll likely get stuck often. That’s normal—step away, return later, and you may see the next move instantly. Over time, this builds stronger working memory, sharper focus, and a more intuitive solving style.

Key Features:

100% manual solving—no automatic notes or validations

Clean, distraction-free interface

Puzzles carefully designed to be solvable without notes

Ideal for players who want a slower, more thoughtful challenge

Mental Sudoku isn’t about racing the clock. It’s about training your mind while enjoying the puzzle.
