I just wish they would create games more challenging than Hardcore. ### 4/5 — 難易度が物足りない *2025-01-16, version 2.7.0* 歯応えのあるパズルゲームを求めてインストールしましたが、ハードコアモードでもいささか難易度が物足りないです。線が交差する回数に制限を設けるなど、さらに難しい問題の開発を期待しています。 ### 3/5 — Would love to pay for no ads *2023-09-21* But I click on the button and nothing happens. In fact, none of the buttyfor purchases work. Argh! ### 4/5 — Can’t listen to music while app is open *2022-03-29, version 2.3.0* As of the latest update, I can no longer listen to music via Spotify while Number Chain is open. Great game - hope this is fixed soon ### 5/5 — My Review *2021-04-29, version 2.2.0* Awesome puzzle ### 5/5 — 정말 재밌어요 *2021-04-25* 스도쿠랑 넘버체인 둘 다 시간 때우기 좋고 뇌기능도 향상 되는거 같아서 좋네요~ ### 5/5 — よく出来たアプリ *2020-12-08, version 2.2.0* 難しい難問はやり甲斐があった ### 4/5 — How are the keys used? *2020-11-20* Most of the game is intuitive but I cannot figure out what I can do with all these keys I’ve accumulated. It is not in the instructions. Would be nice to convert them into value to get the free version.. ### 5/5 — 今までに無い感じ *2020-09-12, version 2.2.0* ありそうで無い今までに無い感じのゲームです。毎回完成すると嬉しいです たまにはヒントがないと進めなくなりますが、100前後のものはヒント見ないで解ける様になりました。 ### 5/5 — Good challenge but *2020-06-08* Freezes occasionally. Even some ads get hung up. That’s my only complaint. ### 5/5 — Suggestion *2020-04-23* The game is really nice would be cool if you can do a 3d version of it ### 4/5 — 시간제한을 없애고 그냥 몇초 걸렸는지 하는게 더 좋을 것 같아요 *2020-02-07* 시간제한이 있으니까 깨고 있다가도 게임 오버 뜨고 광고를 볼 상황이 아니라면 다시 새 게임을 해야되니 김이 빠지는 거 같아요 시간 제한 을 없애거나 시간 제한이 없는 모드를 만들면 더 좋을 것 같아요 **Developer response:** 이번 업데이트에서 시간제한을 없앴습니다. 푸는데 얼마나 걸렸는지는 경쟁전에서 표시됩니다. 의견 감사합니다. ### 5/5 — 재밋네요 *2020-02-05* 클리어한 맵은 다시안나타낫으면 좋겟습니다 하드코어 이상난이도 원해요 **Developer response:** 리뷰 감사드립니다^^ 중복된 문제가 나올 확률은 로또1등 확률보다 적게 되어있습니다. 만일 나오셨다면 ㄷㄷㄷ... 하드코어 이상 난이도는 아이폰X 이상의 경우는 괜찮은데, 16:9화면의 경우 화면크기 한계때문에 어려울 것 같습니다. 한번 고민해보겠습니다. 하드코어까지 마스터 하셨다면 경쟁전을 즐겨보시는 것을 추천드립니다. ### 3/5 — 아니 근데 광고가 너무 많아요 스테이지 하나 깰깨마다 *2020-02-04, version 1.3.6* 한 번씩 광고를 틀면 좀 너무 많은데요 ### 5/5 — 재밌어요! *2020-01-26* 적당히 머리쓰면서 풀기 좋고 중독성이 있네요 ㅎㅎ 아직은 쉬운 단계라 잘 풀리지만 난이도가 올라가면 꽤 어려울거는 같아요~ ## Most critical reviews (10 lowest-rated) ### 1/5 — 재밌는데 한판끝나고 광고 는 좀.. *2020-12-15, version 2.2.0* 세판하고 광고 이런것도 아니고 쉬운거 하나 깻는데 바로 광고나오고.. 제가 문제 푼 시간보다 광고 보는시간이 더 긴거같아요;;; 문제 푸는건 재밌는데 광고가 너무 많네요 ### 1/5 — 英語 *2020-04-19, version 2.2.0* 規約が日本語ではないため起動する気にならず。個人情報ガバガバの人と規約が読める人は試せばいい。 ### 1/5 — 튜토리얼이 안넘어가요 *2018-04-09, version 1.1.5* 투토리얼 15만들기에서 14이후로 넘어가지를 않네요;;; 15가 눌러지지가 않아요.. 아무리 긁고 누르고 다 지웠다가 해봐도 안됨.. 튜토리얼 한다고 시간만 버리고 그냥 지움;; ### 1/5 — Update error *2018-04-03, version 1.1.3* Since the update I can’t play it pls fix the game ### 1/5 — My Opinion *2018-03-26, version 1.1.0* Horrible, tutorial way too long and not to mention, confusing. The idea of it is good but the way it was set up was crap. Have a nice day. ### 2/5 — 発熱が酷い *2021-05-27, version 2.2.0* 微妙 ### 2/5 — Time limit ruins it (updated) *2020-02-03* At the end of the day I can’t play it idly while focusing on something else which was why I enjoyed it. This game does do a lot of things right, but in the words of Reggie, if it’s not fun, what’s the point? **Developer response:** Time limits have been removed in this update. Thank you. ### 2/5 — 광고가 종료가 안됩니다 *2020-02-03, version 1.3.6* 광고가 종료가 안돼서 한판하고 끄고 한판하고 끕니다 너무 불편합니다 버그 없애주세요 이시언 피씨 안꺼져요 ### 2/5 — NOT Hidato *2019-11-12* If you’re looking for a Hidato game, keep looking. There are too few filled-in numbers, therefore not just a single solution. It’s not bad, but not for me. ### 2/5 — Solutions are not unique; not “solvable” *2018-10-24* One simple change would make this so much better, but the ending number of the chain isn’t always provided. This leads to multiple solutions being possible. The “1” is always provided, so I don’t know why the last number isn’t necessarily. I wish the “erase” also worked by dragging. Other than that, the interface feels slick and I enjoy playing. ## Most praised reviews (10 highest-rated) ### 5/5 — 다 좋은데 발열이 심하네요 *2025-03-27, version 2.7.0* 아이패드로 플레이하는데 게임은 재밌는데 발열이 심해요 ### 5/5 — ご褒美にヴァリエーションが欲しい *2024-06-17, version 2.7.0* 楽しいゲーム！脳の体操に最適。じっくり取り組めます。 でも完成時の盛り上がり効果が平坦なので、そこだけちょっと不満でしょうか。 まあゴール出来たらとっても満足しちゃいますけど… ### 5/5 — Better than good *2023-12-23* Very good ### 5/5 — Challenging game *2023-09-29* I really enjoy playing this game. There are a lot of boards at multiple levels and a daily challenge. I would like the developers to add an undo button as well as an option to get back to the menu instead of having to press the Give Up link. While it doesn’t count against the number of boards completed, it displays a new game. An option to save game would also be nice. ### 5/5 — Challenging game *2023-09-23* I really enjoy playing this game. There are a lot of boards at multiple levels and a daily challenge.
