Best no-nonsense sodoku app

A lot of sudoku apps don’t allow you to select a number and enter that number in multiple cells without a bunch of superfluous annoying clicks. The settings in this app really allow you to customize it to how you like to play. It’s pretty no frills, which I prefer, and it’s not constantly being updated with useless changes like other apps. This is the only sudoku app I will use, and I have tried literally dozens. The ads aren’t bad but I did pay for it because I liked it enough I wanted to support the developers. Please never change this app, it’s perfect!!

Absolutely the best classic sudoku app❤️

The app has every control a sudoku player needs, including double notation. The puzzles are handcrafted and look beautiful. The hints are actually teaching you how to become a better player. Six levels of difficulty, for every player level. Themed weekly challenges makes this app very special. I recommend it wholeheartedly.

Great Interface and Teaching Section

The free version is very good but the paid version is cheap and worth the extra few dollars. You can also learn techniques/patterns and see examples of those in the tutorial section. If you use a hint, it’ll give you the name of the technique used and how it’s applied in that specific situation. It’s the best Sudoku app I’ve tried!
