## What is Hyper Sudoku?

A modern Sudoku experience designed for speed, clarity, and steady improvement.

This app delivers clean, distraction-free puzzles that are easy to start and satisfying to master. Whether you have a few minutes or a longer session, you can jump in instantly and focus purely on logic and strategy.

You can play across multiple board sizes, from compact 4×4 to full 9×9 grids, with several difficulty levels that grow with your skill. Built-in time tracking and performance history let you see how your speed and accuracy evolve over time, turning everyday play into meaningful practice.

The interface uses a calm, dark visual style that reduces eye strain and supports longer sessions, making it suitable for daily brain training, focus practice, or casual relaxation.

An optional Pro subscription removes daily limits, enables unlimited play history, provides watermark-free printable PDFs, and fully unlocks 9×9 puzzles along with future Pro features. All purchases are processed through Apple’s In-App Purchase system and can be managed or canceled in your Apple ID settings at any time.

Whether you know it as Sudoku, Number Place, or Nanpre, this is a fast, elegant, and thoughtful way to enjoy the classic puzzle.
