### 3/5 — Has good potential

*2025-04-16*

The game has some good potential but it feels like it's still in beta. There are some quirks and there are basic features missing. One such quirk is that the timer doesn't stop when you are not working on the puzzle. Then a feature that I believe is basic to this style of puzzle, especially when you get into the larger grids, is a pencil. That is: to add in the potential numbers a square can be.

**Developer response:** *** Fixed: requested feature has been added ***
Based on your feedback we have added a feature to add (or exclude) potential numbers: if you press long (1-2 seconds) on a cell, you will get the possibility to select/exclude potential numbers. Thank you for your suggestion. If you like this new feature, please consider updating your review with more stars ;-)
(this new feature is in version 3.7 or upwards of the app, you can force update the app via the App Store).
Regarding the timer that does not stop: this is done on purpose. :-)  A lot of people compete each week in our Game Center weekly rankings. We want to ensure that players don't cheat the timer; they could do that by making a sceenshot of the puzzle, going out of the app (the timer would pause), solve the puzzle (e.g. on paper) and then go into the app again and fill in the correct numbers with the timer showing only a few seconds.

### 3/5 — Manque la fonction notes

*2024-11-01*

Je mets la note moyenne. Il manque la fonction note. A ajouter . J’arrête d’y jouer à cause de ça

**Developer response:** *** La fonctionnalité demandée a été ajoutée. ***
Suite à vos commentaires, nous avons ajouté une fonctionnalité permettant d'ajouter (ou d'exclure) des numéros potentiels : un appui long (1 à 2 secondes) sur une cellule permet de sélectionner/exclure des numéros potentiels. Merci pour votre suggestion. Si vous appréciez cette nouvelle fonctionnalité, n'hésitez pas à ajouter plus d'étoiles à votre avis ;-)
(Cette nouvelle fonctionnalité est disponible dans la version 3.7 ou supérieure de l'application. Vous pouvez forcer la mise à jour via l'App Store.)

### 5/5 — Great game, amazing developers!

*2024-10-07*

Great game, exactly as advertised. I had a complaint about a game feature, and the developers took my feedback and made changes based on that. I couldn’t believe it! I highly recommend this game, worth every penny.

**Developer response:** Thank you for your kind words. And thank you for your feature suggestion. Hope you continue to enjoy the game :-)

### 3/5 — No settings menu?

*2024-10-05*

Great game, exactly as advertised. Only gave 3 stars bc I can’t find a way to turn off the auto-check feature, that tells me whether I’m right or wrong as I go. It ruins the fun! Maybe the new update will fix that.

### 5/5 — Fun and ad free

*2024-02-17*

Challenging and as the title says, NO ADS. Also, no internet needed and NO DATA TRACKING. Inexpensive full version supports the developers.

**Developer response:** Thank you for your wonderful review. Please continue to enjoy and spread the word :-)
