What Makes SudoKoi: Smart & Clean Sudoku Stand Out
〉SudoKoi – Beautifully Minimal Sudoku
Simple. Elegant. Focused.
SudoKoi is everything you love about Sudoku – refined to perfection. With five difficulty levels, support for up to nine simultaneous games, and thoughtfully designed tools like note-taking, candidate tracking, and smart highlights, SudoKoi lets you focus on what matters: solving.
No ads. No clutter. No distractions. Just Sudoku.
〉Smart, But Never In Your Way
SudoKoi enhances your experience without taking over. Subtle features like error checks, highlight helpers, and number button indicators keep the game flowing smoothly – without solving it for you. It feels natural, intuitive, and satisfying.
〉Designed for Calm
SudoKoi is carefully crafted to look and feel great on all your devices. The clean, paper-like interface is both beautiful and functional, with every detail made to disappear into the background – so the puzzle takes center stage.

Player Experience Highlights
Community Insight:
This app is designed really well, just missing settings that other apps have, such as "disable highlighting rows/columns/boxes" or "show errors" which we prefer to play on. We'll probably stick with another app unless this one adds settings so you can pick your preferences.
This is by far the best app Ive tried. It supports Split View which was how we originally found it. Not to mention there are no ads and it merges sudoku and killer sudoku into one app.
This is a wonderful app, and the only sudoku app that Ive been able to find that supports writing in the numbers with the Apple Pencil. To push it over the top, Id love to see some options in typography and contrast so that its a little easier to distinguish rows, columns, and boxes.
