The initial levels are free, with no ads, and they give you many hours of fun. Then you can purchase extra levels. ### 5/5 — Fajn hra *2023-07-16, version 4.1* Prima hra a skvělé provedení i jako několik dalších her od těchto vývojářů 😉 ### 5/5 — great *2023-06-29* very funny, thanks a lot! ### 5/5 — Fun quick game *2023-05-06* I saw this game in an ad I’m a big fan of sudoku this is a lot like it but also very different worth a try if you like puzzles ### 5/5 — Fun *2023-05-04, version 4.1* So far. It’s a fun game. It makes you think. ### 5/5 — Awesome puzzle *2023-05-03* Quite logical can be very addictive! Well done! ### 5/5 — Like all *2023-04-07* I enjoy all conceptis puzzles. Packs are priced similar to puzzle books at stores and give weeks of solving enjoyment. Get a free puzzle weekly but always easy introductory type...good puzzle game ### 5/5 — Good *2023-03-27* Nice logic puzzle game, no ads, plenty of free levels ### 5/5 — Fun game *2023-03-16* Once I figured out how to play this game is lots of fun. The instructions will help a little but playing several times in a row will help you figure out how to play this game. Don’t give up once you have mastered it this game is a great way to spend your time. ### 5/5 — Brilliant *2023-02-07* High quality puzzles, plenty of free content and very reasonably priced extra packs. No adverts. Recommended. ### 5/5 — Great puzzle for logic fans! *2023-01-21* Really great logic puzzle for fans of Sudoku, Hashi, etc. And as always a well-designed app. ### 5/5 — パズルアプリで一番好き *2023-01-14* 無料の問題も週一で更新されてこのシリーズずっと楽しくあそんでいます。 ### 5/5 — ハマる〜 *2023-01-02* めちゃ面白い！ フリーでたくさんできるのも嬉しい‼ ### 5/5 — A fun challenge *2023-01-01, version 4.1* Good puzzles ### 5/5 — Love it! *2022-12-09, version 4.1* Love it! ### 5/5 — Check *2022-11-29* One thing I love about Conceptis puzzles is the "check" button. I do these puzzles to relax at the end of the day, and being able to click the "check" button and have it say that there are no errors is very reassuring, especially after difficult days. ## Most critical reviews (10 lowest-rated) ### 1/5 — Broken *2022-10-28, version 4.1* Game is fine, but no matter what you do or what option you select, it NEVER STOPS asking you to rate it. Even if you rate it! Even if you click no! It. Never. Stops. ### 1/5 — Don’t spam me for reviews *2022-05-19, version 4.1* Don’t spam me for reviews ### 1/5 — Terribly confusing *2017-06-19* It doesn't make any sense, doesn't explain the rules at all. ### 1/5 — Good app; very expensive, though *2016-04-04, version 3.0* Buyer beware: you could end up spending thousands of dollars on Conceptis applications. Read on for details. This review includes the eight applications published on the iOS app store by Conceptis (Nurikabe, Tic-Tac-Logic, Link-a-Pix, Pic-a-Pix, Hashi, Sudoku, Slitherlink, and Fill-a-Pix). First off, their applications are well built and include many fun puzzles. I especially enjoy the weekly free puzzles, though it is a little irritating that they go away after four weeks and are not saved. However, the biggest problem—and I've noticed this mentioned in some reviews for these applications—is the high cost of puzzles. They are well done and fun, but when the costs are summed, they are rather high. There are 31,380 puzzles total (as of today) across the eight applications, ranging from very simple to rather complex, which would cost you a total of $3511 (not including tax). This is on par with the cost of licenses for professional-level applications. I think it's quite disingenuous of Conceptis to charge so much for the puzzles. When averaged (across all 8 applications for the entire range of puzzles), they total just over 15 cents/puzzle. That may not sound like much, but it can add up quickly. To contrast this, LogicPicColor, an iOS app like Pic-a-pix, has 16,778 total puzzles which cost a total of $30 (plus tax), averaging at a third of a cent per puzzle, about 50 times less than those from Conceptis. Now, LogicPicColor has some shortcomings and is not nearly as well done as the apps from Conceptis. Nonetheless, I don't believe Conceptis's apps and puzzles are worth that much of a premium, and will therefore be satisfied to look elsewhere. Perhaps someday they'll offer sales or discounts for puzzle bundles—ever since the apps were released, I've hoped for this, to no avail. ### 2/5 — 途中までは楽しいが *2025-04-27* 超上級が仮置きするしかなく、理詰めで解けないのがつまらないです。美しくない。 **Developer response:** 理詰めで解けないとのこと、でご意見いただきありがとうございます。よろしければ、問題の箇所の画像など問い合わせメールにいただけましたら、見させていただきたいと思います。 ### 3/5 — Conceptis games rock! *2018-03-04* Another addictive game from conceptis. Shame I have to pay so much to carry on playing though, so two stars dropped. ### 3/5 — Love the game, but.... *2017-02-13, version 3.2* I love nurikabe, and this is a really awesome app BUT I'm giving it 3 stars because they don't have that many puzzles for free. They have about 90 and then you have to pay for more. So this only lasted a week for me :( ### 4/5 — Great games, but very expensive *2025-03-10* Great game, but if you are fast in doing the puzzles, the free ones are very limited, and to buy more it’s insanely overpriced 🥹 **Developer response:** Thank you for your feedback. Our policy is to provide a top quality puzzling experience in a relaxed atmosphere without the disturbance of ads and other annoying messages. Therefore, to continue maintaining the app and provide more new puzzles every week we have to charge for the extra content. We thank you for your understanding. ### 4/5 — 仮置き機能が欲しい *2022-10-20* とても好きなパズルですが、壁もドットも色が変えられる仮置き機能があれば上級にも挑戦しやすいなあと思います。 ### 4/5 — 引き継ぎ *2022-07-03* 新しい機種へのデータの引き継ぎ方法を教えてください。 **Developer response:** iOS機種への引継ぎでしたら、古い機種で設定⇒バックアップ。新しい機種で、設定⇒リストア で履歴が戻ります＾＾ ## Most praised reviews (10 highest-rated) ### 5/5 — 難易度が絶妙 *2026-03-26* 簡単なのは何も考えず遊べて、難しいのはしっかりと考える必要がある 気分転換にぴったり⭐︎ ### 5/5 — かべパズル定期的にやりたくなります *2025-04-24* 昔から紙でやってました。 無心で集中できるのと達成感が好きです。 このアプリは手軽に出来て良いです。 ### 5/5 — Great logic game *2025-04-07* Well executed with practical features to make it logistically simpler to play ### 5/5 — perfect app *2024-03-13, version 4.1* no ads and the ui is perfect conceptis ltd we love uuuuuu ### 5/5 — Love all your puzzles *2023-11-29* Would really love to see an app for your Skyscrapers puzzle too ### 5/5 — good *2023-11-03* 上級は面白い ### 5/5 — Addictive!! *2023-10-21, version 4.2* Found this app and can’t stop playing 🤓 ### 5/5 — 更新に期待 *2023-10-18* 更新ありがとうございます。 好きなパズルなのでUIが見やすくなり嬉しいです。 難しい問題になると仮置きが発生するタイミングあるので、仮置き機能が欲しいです。 （確定マスが見えてない場合があるかもしれないですが） 特に空白が広く数字が大きいと必ず一旦仮置きをしています。 仮置き数は複数あれば嬉しいですが、 だいたい1つあれば賄えますので仮置きボタンと、それを確定するか削除するかのボタンがほしいです。 今は一旦仮置きして、後々詰まったら仮置き開始した段階まで戻るを連打しています…。 上級まではだいたい無しでもこなせますが、それ以上になると仮置きがないとやるのがしんどいです。 パックも気軽に上級が買えないので、検討して下さると助かります。 ### 5/5 — 。 *2023-09-27* 仮置きした数字の色が変えられるようにして欲しい ### 5/5 — No ads, great puzzles *2023-09-25* It started off a little bit confusing for me, but once I got more familiar with the rules, this game has become so addicting. Plus, no annoying pop-in ads, I’m seriously considering purchasing the extra puzzle bundles. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
