### 2/5 — Gameplay disadvantages. Better to use webpage.

*2026-08-04*

I currently live in a very remote area and very much appreciate being able to save variant sudoku puzzles to my device; this app is wonderful for that. However, often with the variant sudokus I enjoy (ones with Fog or that require you to draw out lines) there is no feature to do that. All but one Fog sudoku I’ve played on this app shows the cleared game board which defeats the purpose. There’s also only one set of colors which doesn’t help when using them to differentiate digits and solve the sudokus. Overall, a decent app but lackluster. Would love to see improvements. Not worth the price in my opinion.

### 3/5 — Close but not quite

*2026-05-20*

I love that you guys have made this app. And it’s great! But I wish the line tool worked like on the web app. Color options, diagonal line drawing etc. 

It would be nice if it worked the same way. 

Great work on this though! Very helpful.

### 3/5 — Improving the app?

*2026-04-20*

This app is good. Sven’s can you please update it so it is as good as the one on your web page. I don’t mind paying more for an update version.  I only bought this a couple of days ago and I find I am just using you website one as it is so much better.  I still a beginner at these puzzles so to have a check option to see if I am on the right track, like you website has is a must.  Thanks for your devotion to the sudoku community. Blessings

### 2/5 — Out of date

*2026-03-21, version 1.3.1.1*

This was a great app, but is so out of date now it does not support lots of tools available on the web.

### 4/5 — Almost perfect app!

*2026-02-28, version 1.3.1.1*

Would love to see the line drawing tool added and the ability to play fog sudoku puzzles from the website. Other than that great app that I love!

### 5/5 — Can’t wait to try this out!

*2026-02-27, version 1.3.1.1*

I really like the CTC web interface, my problem is that those puzzles are a bit too hard for me. This interface is by far the best for working sudokus that I’ve found on the App Store, and it works really well on a phone.

### 1/5 — Disappointed

*2026-02-19, version 1.3.1.1*

I’m very disappointed in this app compared to the free website. When entering pencil marks they are not flagged as conflicting. a vital part in learning sudoku. I hope this is resolved soon

### 3/5 — Expected a little more

*2026-02-08*

Have been using your website for months now. And theres a lot of stuff not present in the app which I just downloaded and paid for. 1) no alphabet tool? 
2) cant change the colour set (for somebody who’s colourblind, to be able to choose his own colour set which he/she is comfortable with would work wonders)
3) on importing a sudoku from logicmasters, the rules dont get imported, so if you’re playing after a break you wont be able to read the rules again. 
4) cant change pen tool colour?

### 4/5 — Almost perfect

*2026-01-13*

Would give 5 stars but lately whenever I import a puzzle from the cracking the cryptic team the puzzle instructions, or notes, defaults to a standard set of instructions, rather than the bespoke rule set. Hopeful for a quick fix on this.

### 1/5 — Desperately needs update

*2025-12-25, version 1.3.1.1*

Rules never transfer over to app; And fog sudoku is not supported in the app. I just wouldn’t use this over the webpage.
