Great APP

This is a great app.

The best feature for me is the custom puzzle feature. It allows you to put in your own game or from newspapers etc.

There is a slight flaw in the notation feature. When you solve a cell the app doesn’t necessarily eliminate that number from the row column and square. Should be an easy fix.

Love it! Get it!

simple game app

I’ve tried a bunch of sudoku apps and found this one to be OK.

Pros: dark mode. No full screen or overly interruptive ads (in the free version). Nice set of options to control effects, input method, etc. I’m glad to see the “digit first” method is an option.

Cons: it doesn't remember the dark mode setting. When you reopen the app it defaults back to light mode.

No option to immediately flag wrong numbers.

...not a “con” per se but a suggested improvement: “dark mode” could have less contrast. = even less strain for the eyes.

Also, PLEASE consider putting a “dark mode” filter / tinted overlay on the ad area. Stark white or brightly colored flashing ads kind of defeat the purpose....

THE Best

I've played at least a dozen. This one is by far the best one. Great features, non-obtrusive, very stable, no gimmicks.
