### 4/5 — Good puzzles!

*2024-10-03*

Started playing this after seeing the developer n Jeopardy.  The puzzles is great, and reminiscent of other circuit completion puzzles like Nikoli Slitherlink, and Kaser’s Willa’s Walk.

So why four stars?

The app itself feels like a minimum-viable product and could use a little more work. In particular, the lack of an undo/redo button is not great. I find myself having to hit reset if I paint myself into a corner and would prefer to tap undo a few times.  

Also when you start the app up, you have to do some menu diving to get to your last puzzle. This shouldn’t require more than a single tap.

**Developer response:** Great suggestions! We used to have undo/redo, but replaced it with pencil mode. I will seriously consider putting it back in. The comment about menu diving is right on the money, and I will definitely implement it. Glad you saw me on Jeopardy! Especially glad you shared your suggestions.

### 4/5 — Fun Game

*2024-09-27*

Would be 5 stars, but I can't seem to go back and re-play completed puzzles? I love the minimal interface.

**Developer response:** Good suggestion. I didn't think people would want to replay completed puzzles, but of course it makes sense.

### 4/5 — Gute Rätsel, wirkt aber noch unfertig

*2024-08-11*

Rätsel sind gut. 

Aber obwohl ich „Musik aus“ eingestellt habe, beginnt die Musik nach einem fertigen Rätsel wieder zu spielen und unterbricht das Hörbuch, dass ich hören will.

**Developer response:** Danke für den Bericht. Entschuldigung für meine langsame Antwort. Ich habe das Problem behoben.

### 4/5 — Nearly Impossible levels require guessing?

*2021-11-11*

Love the game, I’m playing thru a second time. But I feel like some of the Nearly Impossible levels can’t be solved without guessing. Is that true?  I feel like I’ve learned all of the tricks to solve.

**Developer response:** Thanks for the feedback! It is possible to solve every puzzle without guessing, but it isn't easy. Pencil mode will make it easier to explore possible paths, and there's a new Puzzle of the Day subscription option. It's available now on iOS 15!

### 3/5 — Dump the timer

*2021-09-10*

The puzzles are enjoyable , but the timer and the insulting scores it generates ruin the fun. So I took a couple minutes, can't I just enjoy it? Finished the free puzzles then deleted it.

**Developer response:** Thanks for your comments. We've made the timer optional. Please try the updated version.
Best, David

### 4/5 — Great, but a bit broken

*2021-05-30*

Amazing game, but when I try to buy an individual pack, I’m unable. I click on “Buy” but nothing happens. Will amend review when fixed!

**Developer response:** We found and fixed the problem. Version 1.1.8 is now available with the fix. Thanks very much for reporting this!

### 5/5 — Fun game - quite challenging

*2021-01-23*

A lot of puzzle games on IOS are too easy and cluttered with ads. This game is neither of those. Complex enough to keep you intrigued, and no constant ads. Will continue to play. 5 stars.
Will

**Developer response:** Thanks, Will! It's great to hear that you enjoy the game!

### 1/5 — Fun game, 95% of it is behind a paywall

*2023-06-01, version 2.0.15*

Figured out how it works only to be confronted with a paywall to access the rest of the game and I can’t seem to replay any of the old levels

### 1/5 — Ce n'est pas gratuit

*2021-12-21*

Il y en a assez de cette fausse gratuité, c'est lourd.

**Developer response:** Tous les puzzles sont désormais gratuits.

### 1/5 — Broken

*2021-10-06*

Says 94% after completely finishing the first level

**Developer response:** Thanks very much for reporting that. We've overhauled how we track puzzle completion and will thoroughly test it before the upcoming V2 release. Sorry you had that experience. We have tens of thousands of users and this is the first report we've had of this issue, but that doesn't make it OK.

### 2/5 — Good game, but…

*2023-12-05*

A good, challenging puzzle game. But there’s no reason for it to run as hot or burn through my battery like it does. So what’s it doing in the background?

**Developer response:** Thanks for the feedback. We use profiling tools to measure energy consumption, as well as using the app on a variety of devices, and we haven't ever seen this behavior. If you get a chance, please send some additional information to info@goodthinkinggames.com. Let us know what device and model you're using, what version of iOS, and whether you notice the problem particularly when a particular screen is visible. Best, David

### 2/5 — fun concept, ludicrous price

*2021-12-13*

was excited to play, i’m happy to spend a few dollars, but 17 dollars PER PACK? no thanks

**Developer response:** Now all of the puzzle packs are free. We introduced occasional (infrequent) ads, but you can skip them or turn them off (for a nominal fee). We hope you like the new version.

### 3/5 — Très bien, mais peu de contenu gratuit

*2022-08-11*

C’est un très bon jeu je trouve, stimulant c’est vraiment sympa, mais le jeu ne limite qu’à une catégorie sur 17, donc ça ne revient qu’à 50 puzzles, ce qui est trop peu. De plus impossible de refaire de précédents niveaux sans désinstaller l’appli

### 3/5 — Nice game, price too high

*2022-01-17*

It took me very little time to go through a set of problems I was charged for. Doesn’t make sense, and not in line with the cost of other games.

**Developer response:** Thanks for your feedback. We're committed to being a free app, but we do need some revenue! Stay tuned and we'll see what we can do.
Update: We've made all puzzles free, and introduced infrequent ads to make it feasible to continue to support the app.

### 3/5 — Okay puzzle, few free levels

*2021-12-23*

See the title.

**Developer response:** Now all levels are free. I hope you give it another try - some of the levels are extremely challenging!

### 3/5 — Amazing Game (with bugs)

*2021-12-22*

The game is a great idea (how could you go wrong with an NP-complete problem), and the puzzles are designed well too :).

However, it seems in the newest update, many of the levels that I'd already finished are now marked incomplete. So, the packs I was in the middle of are now especially difficult to navigate.

Moreover, while the pencil mode is super helpful, in hex puzzles it does not connect with the normal drawing mode, leaving a pretty significant discontinuity.

Thanks for the help!

**Developer response:** Our new version is a complete rewrite, and we've worked really hard on quality. All of the puzzles are free. We introduced occasional ads, but they're infrequent, skippable, and can be eliminated. I hope you give it another try.

### 3/5 — $18 for the full game?

*2021-11-28*

In my opinion, the price is steep for such a minimal game.

Additionally, you cannot play the “giant” levels on iphone devices, you HAVE to have an ipad? Why can’t the dev just let us zoom in?

**Developer response:** We listened to your feedback, and we made all the puzzle packs free. To do that, we introduced occasional (infrequent) ads, but they're skippable and removable. Also, now you can play even the giant levels on any device.

### 5/5 — Addicting game

*2024-06-05*

Just downloaded this today and am already addicted!

**Developer response:** Thanks for the feedback! Let us know if you have any suggestions for improvements.

### 5/5 — Great game to keep you sharp

*2023-11-14, version 3.2.7*

I forgot about this game for a bit, after I got a new phone - but I do hope it is doing well l - as I am not getting back to it and getting addicted again! :)

### 5/5 — Great game but the scoring is confusing

*2021-12-26*

I love this game! Unfortunately I don’t understand how it’s scored. At the end of each level a percentage is given based on the number of grid spaces in the puzzle, however it’s unclear what the scoring criteria are.

Still worth every penny since it’s satisfying enough to solve the puzzles.

A very challenging game and nicely designed!

**Developer response:** The maximum score for a puzzle is based on the number of grid cells, as you noted. Depending on how hard the puzzle is, there's a time delay before the score starts going down. It's purely based on solving time.

### 5/5 — Brilliant game

*2021-07-13, version 1.1.8*

There’s very few bells and whistles, but this is pure puzzling at its best. Simple to learn, but increasingly challenging. You get a decent amount of free puzzles, and the paid ones are reasonably priced. Although all the puzzles take the same form, progression is excellent. So far I’ve completed just over 570 of them, with each one taking between 1 and 5 minutes. It’s a great way to while away the time. There are plenty of far flashier games in the App Store, but very few that are as satisfying as this.

### 5/5 — Great game.

*2021-06-22*

Great game. Adding 2 features would make it perfect. 1) An undo button, with the ability to undo an unlimited number of moves. 2) “Guess” mode. Sometimes you get to a point where you can’t figure out the next move to make. In those cases it would be super useful to be able to switch to guess mode where the lines you draw are a different color or something. If you proceed with drawing additional lines after the guess and encounter a contradiction you know your original guess was wrong and you can then undo all your guess moves and try something else.

**Developer response:** Thanks for the great ideas! We recently released guess mode (also known as pencil mode). We think it eliminates the need for undo - the concepts kind of overlap.

### 5/5 — Hitting “Buy” Causes Crash (Edit: Fixed!!)

*2021-04-24*

First off, I love this game, it’s an excellent puzzler and gives the same puzzle high as the likes of sudoku.

However, when I went to buy all packs on my iPhone XS Max, I hit “Buy” and the app crashes. This continues to happen after restart the app. I want to buy all the content for $4.99, but it won’t let me!

I will definitely amend my rating to 5 stars if this issue is fixed.

Edit: Updated rating to 5 stars. Within a couple days of this review going live, the developers patched the game to fix this bug. Amazing turnaround. As a software developer myself, I love seeing this attention to customers. Wish I could rate higher than 5 stars but hopefully the $4.99 I spent to buy the packs is token enough.

**Developer response:** Thanks for the updated review! We are constantly trying to make the app fun, challenging, and flawless, and your feedback helped us along toward our goals.

### 5/5 — Absolute best puzzle game!

*2021-04-12*

I absolutely love this game. You will be challenged. Math nerds, this is for you!!

**Developer response:** Thanks so much! We're delighted that you like it.

### 5/5 — The best puzzle game!

*2021-03-19*

Absolutely loved this game. Just the right amount of challenge to keep your brain engaged, but also not hard enough to make you bang your head against the wall. Also, I love the animation of the puzzles— so satisfying!

**Developer response:** Thanks! It's really great to hear comments like yours. Lots of great new features coming!

### 5/5 — Супер

*2021-02-09*

Класс ультра вери найс

**Developer response:** Большое спасибо!

### 5/5 — Молодцы!

*2021-01-28*

Игра прекрасная, иногда заставляет серьезно подумать. Понимаю что уже мыслю быстрее и решительнее, меньше медлю. :) Есть русификация, поэтому 5 звёзд.

**Developer response:** Большое спасибо! Дайте мне знать, если у вас есть предложения, на info@goodthinkinggames.com.
