### 5/5 — Fun and challenging

*2023-11-05*

I enjoy the many ways this game can be played. I am not sure what other reviewers had reason to be so negative, tho I do notice most are more than a year old.

### 3/5 — Good, but no keyboard input

*2022-10-28, version 3.3.1*

A good sudoku app, but disappointing that with an external keyboard, the numbers don’t map to the numbers. It is probably really easy to implement this, and would be a great addition.

### 1/5 — Problem!

*2022-05-25*

It freezes when I try to choose a version to play

### 5/5 — Different levels

*2022-05-07*

Different levels are available starting easy to tough. 4 different types.

### 5/5 — Wonderful app

*2022-04-24*

Wonderful app. I like the following. One, I can choose which sudoku game to play. Two, it gives me the option to choose between a dark or light design.

### 5/5 — Great app

*2022-04-23*

Great app. I like the options to select the level of difficulty and color the wrong numbers red.

### 1/5 — Restore old newspaper mode

*2022-03-19*

Can you please go back to the old method. This new technique is super inefficient. Dont fix what is not broken!

### 1/5 — Latest release newspaper mode is super clumsy to use

*2021-12-29*

I am a freeloader so I do not have a real right to complain. But I have been using the app for many years and the new interface when in newspaper mode cannot seem to be turned off. Being forced to pick a number in the pad, then tapping it in the grid, forcing me to turn off the number selected in the pad to change to the next number is a terribly inefficient and non-intuitive design. I am not pleased. I hope I can restore to an earlier version.  The prior version I would rate a solid 4 plus.

### 4/5 — 3.1 broke after PadOS 14.2 update, but reinstall fixed it

*2020-11-13, version 3.1*

This was a decent little app (after glitches a few years ago) until I updated my IPad Pro to OS 14.2

Following the upgrade the app shut down almost immediately. However, deleting the app and then reloading it (and then restoring the payment recorded by Apple) seems to have fixed it. So, one more tiny glitch, but back to being handy for those times when you’re stuck in the middle of nowhere with nothing to occupy your mind.

### 3/5 — Crashes with 14.2 update

*2020-11-12*

This is my favorite app on my iPad, the only problem is that with the 14.2 u[date the app crashes every time that I try to start it.
