Learn a lot about the logical ways to remove candidates. However, I am greatly disappointed when I get a “brute force” ( = guess ) hint with 20 squares yet to go. Either a guess is truly required or the logical hint is too difficult to explain in the app. Either way, I really don’t care to pay for these games that end like this. The claim is that properly structured games should not require guessing. Is there a way to save the game state so one can return to the point of the first brute force guess….after wandering in the forest of guesses? ### 4/5 — Brain Gain *2026-05-24, version 3.5* Keeps me working that brain and thinking. ### 4/5 — Two issues, but still best Cross Sums app I found *2026-01-21, version 3.4* The game lets you rule out options, like saying I know “134” doesn’t work, but “125” does. Undo doesn’t track such changes, I wish it did. Also, its error reporting would be better if it tracked when the rules are broken, such as repeating a number, instead of highlighting a sum that disagrees with the solution, because my most common mistakes are due to typing errors, which are easily missed, not logic errors. [Response to dev response] I reported the bug with undo about 3 years ago and was told it is too costly to fix. As to highlighting simple errors, I have “Show errors” on, and it absolutely would not be a spoiler to circle the two “1”s I mistakenly entered, and I hate that the option shows me any spoilers. I have responded with more details to the email provided. ### 4/5 — Two issues, but still best Cross Sums app I found *2025-12-23, version 3.4* The game lets you rule out options, like saying I know “134” doesn’t work, but “125” does. Undo doesn’t track such changes, I wish it did. Also, its error reporting would be better if it tracked when the rules are broken, such as repeating a number, instead of highlighting a sum that disagrees with the solution, because my most common mistakes are due to typing errors, which are easily missed, not logic errors. ### 5/5 — Studman *2025-05-18, version 3.2* Difficult but doable, lots of fun ### 3/5 — Good but flawed *2025-03-25, version 3.2* I am enjoying this new-to-me type of puzzle but I can’t tell you how many times I’ve “solved” a puzzle and satisfied all the sums just for the app to tell me I’m wrong, and then I have to guess which of the multiple valid solutions the app actually wants me to enter. Please fix it so that all valid solutions are accepted ### 5/5 — Cross Sums forever! *2025-03-19, version 3.2* I truly enjoy this app. The only improvement I would like to see would be a help feature where I could learn some more advanced solving techniques. This would be a huge undertaking. The skills included in the app are the standard ones, but where there are many options for learning advanced sudoko techniques, I find very limited options for advanced Kakuro techniques. I can solve the hard level with time but sometimes get stuck on the hard plus level. I need new techniques before I try the truly challenging puzzles. Update! I love being able to use hints when I am truly stuck! Thank you. I would like a few tweaks. Once I’ve filled in lol the pencil marks on my own, if I turn on auto fill it adds possibilities I have already eliminated. Since I can’t use the hints unless it is on, I then have to remove lots of options I have a lady eliminated. ### 5/5 — Best game *2025-02-14, version 3.1* I love Kakuro puzzles and this app is wonderful. Each puzzle offers a challenge but is solvable. Never too hard or too easy ### 5/5 — Challenging but fun *2025-01-26, version 3.1* If you like Sudoku and want to stretch your logic skills, this game is for you. Don’t be intimidated, there are hints and help until you get the hang of it. The controls are well done and easy to use. ### 5/5 — Lovely puzzle game *2024-12-29, version 3.1* Great puzzle game, lots of replay, available offline ### 5/5 — Feels like an app you’re happy to support *2024-12-25, version 3.1* Truly no ads, help when and where you want it, good ui, and challenging levels for every range of the skill spectrum. 10/10, there is no way to do better. ### 5/5 — Fun and free *2024-10-24* All the apps I’ve tried from this company have had well made puzzles that are fun and ad-free, with a large amount of free puzzles! I’m reviewing to make some feature requests, since the request button didn’t work in the app: some of these apps have hints, while others don’t - I wish they all did. It also would be nice to have customization options for the colors on the puzzle (e.g. blue instead of orange, or reverse black and white cells in Kakuro). The other thing I would find helpful is the option to have a cursor mode in more games, like the one in Fill-a-Pix. ### 5/5 — ヒントについて *2024-10-09* なぜ、間違いがあるときはヒントが使えないのですか？ **Developer response:** 只今アシスタント機能を準備しております。まもなくリリースしますので、楽しみにしていてください。 ### 5/5 — 使いやすい *2024-09-25* 鉛筆でやっているのと同じ感覚で、それをもっと便利に使えるのがいい。 無料だと嬉しいけれど、そうしたら広告が出てくるんでしょうね。 ### 4/5 — Fun and easy to use *2024-09-14, version 3.0* Fun and easy to use. However some pictures are a bit weird or can only be worked out when you squint! ### 4/5 — It’s ok *2024-08-24, version 3.0* It’s ok Too expensive to buy extra Only do weekly bonus and original free ones. ## Most critical reviews (10 lowest-rated) ### 1/5 — 仮定って… *2025-08-20* 超上級でヒント使ったら仮定で数字消し始めたんだけど…それはなんか違うじゃん **Developer response:** レビューありがとうございます。カーソルについて、よろしければ詳細を問い合わせメールにいただけましたらご検討させていただきます。 度々ご不便をおかけし申し訳ございません。ヒント使用につき、疑問のある個所について画像等いただけましたらお調べさせていただきたいと思います。 ### 1/5 — Stop asking me to rate this game *2023-07-15, version 2.7* Thanks. Edit: please stop. Edit: Please? Edit: Please?? ### 1/5 — 残念です *2023-01-30* 本家のカックロに慣れているせいか、シマができる問題が多く違和感があります。時間潰しにはなります。 ### 1/5 — 問題の作りが雑 *2022-05-14* 最終的に計算じゃなくトライアンドエラーを繰り返さないといけないゴミ問題のせいでモヤモヤさせられる **Developer response:** よろしければ、詰まった箇所など問い合わせメールに画像等いただけましたら、できる範囲で回答させていただきます。 ### 1/5 — Worst app I’ve tried on AppStore *2021-03-19* I love this game and the features are really cool. But why in the world it freezes my phone? I closed all the other apps because I thought my phone ran out of RAM because of too many active apps. But it didn’t help. It took like 5 minutes for the phone to unfreeze the first 2 times. And I barely managed to force restart it the third time as it didn’t unfreeze. I don’t want to risk my phone anymore so I deleted the app after it. And it’s a new phone so its performance is good and I haven’t had it happen with any other app. Such a disappointment( **Developer response:** Sorry to hear about this problem. In case you are able to do this, please send us an email to support@conceptispuzzles.com so we can understand more and fix this issue. ### 2/5 — Meine Lösungen werden nicht akzeptiert… *2023-08-08* …obwohl sie stimmen. Programmiert es bitte so um, dass mehrere Lösungen stimmen, dann gibt es auch mehr Sterne. Eigentlich hab ich diese Art von Rätsel immer sehr gern gemacht, aber es verdirbt die Freude am Spiel, wenn die eigene richtige Lösung nicht akzeptiert wird. **Developer response:** Thank you for your feedback. The reason some of your solutions are not accepted is because you are missing one of the rules. For example, the rule which is most frequently missed is that the same number cannot be used more than once in a sum combination. In case you still have problems, please send us one of your solutions and we will explain where you made the mistake. ### 2/5 — ゲーム自体は面白いけど *2022-03-23* 自分の環境だけかもしれませんがプレイ中に何度もフリーズしてしまい、再起動にもとても時間がかかります。のでアプリ消しました。ゲーム自体は楽しく遊んでいたのですごく残念です。 ### 3/5 — 繰り返し楽しんでます *2026-07-24* とても楽しんでますが、久々にやったらBIGのげーむについて、1番下の列が途中までしか表示されず、スクロールもできず、残念な状態です。 **Developer response:** ご不便をおかけし申し訳ございません。手元のデバイスで確認してみましたが表示の不具合が見つかりませんでした。もしできましたら、問い合わせメールに画像をいただけましたらお調べさせていただきたいと思います。 度々すみません。アプリのバージョンが最新(ver.3.7)になっているかも併せご確認いただけましたら助かります。 ### 3/5 — Does not save anymore *2026-04-11, version 3.5* Since the last upgrade, the app no longer saves my weekly puzzle in progress. This is the same on all Conceptis apps. These are my favorite puzzle apps, but I can no longer play the more challenging ones due to having to start over every time I open it. ### 3/5 — Have to get it their way *2025-09-18, version 3.3* Sometimes you can have a combination that works, but won’t solve the puzzle because they have it coded for a different assortment ## Most praised reviews (10 highest-rated) ### 5/5 — Fun and challenging *2026-05-01, version 3.5* The games are a great way to stimulate your mind. If you enjoy a challenge, this a great game for you! ### 5/5 — Good fun! *2026-04-29, version 3.5* App keeps the game interesting, challenging, and there’s some nice helping tools. ### 5/5 — Challenging & Gun *2026-04-04, version 3.5* Great game to stay sharp with math skills ### 5/5 — Great Kakuro *2026-02-27, version 3.5* I thoroughly enjoy this version. I play the hardest and can usually finish in 60 minutes. ### 5/5 — Favorite “game” app *2026-01-29, version 3.4* 👍🏻👍🏻👍🏻👍🏻👍🏻 ### 5/5 — No ads!!!! Really free!!! *2026-01-16, version 3.4* Not a con. No ads. Really free. ### 5/5 — Excelente *2025-11-16* Melhor jogo desse tipo ### 5/5 — Amazing App! *2025-10-18, version 3.4* I love playing this game, and this app makes it so good! The UI is very easy, and not cluttered. You just focus on the game, not on ads and crazy distractions. ### 5/5 — Almost perfect *2025-07-26, version 3.3* Only feature I like to add is being able to highlight and add pencil marks to multiple cells in one operation ### 5/5 — Play these daily and love them *2025-07-15, version 3.3* I love playing these puzzles and there are no pesky adverts interfering with the focus. Different difficulty levels to choose from, whether you just want to spend a quick-fix few minutes or are in the mood for something more challenging. I like that there is the option to check progress to see if you’ve made any mistakes. The Show Hint option can be handy, though I’d prefer it, if it also worked without having to use the option to auto-fill all pencil marks. Great app, thank you. 😊 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
