Nikoli has the BEST sudoku puzzles

If you’re looking for a sudoku app, this is the one to get. No ads, no nonsense you get with other gaming apps. Super high quality puzzles. Free version has several puzzles of varying difficulty to try. Premium version is also worth it—100%.

The app has a clean interface, and quality of sudoku puzzles is still unmatched at all skill levels. They are always thoughtfully designed, and you can sense a “flow” in the logic when solving (randomly generated puzzles often lack this experience).

I am a long-time fan and supporter of Nikoli puzzles from when they used to appear in GAMES magazine back in the early 2000’s and their online puzzle platform (please bring this back!!).

I miss the multi-player environment of their online platform where you could see how others solved the same puzzle, and compare times. It helped me improve my skills immensely. I hope they can develop their apps further to bring some of that magic back. 🤞.
