Enjoyable challenges. ### 5/5 — 재밌어요 *2022-08-17* 단순하고 심심할때 하나씩 풀어가는 맛이 좋아요! 추천 ### 5/5 — Antibus *2022-07-09* Amazing!!! 👍👍👍😊😊😊 ### 5/5 — Гуманитарий в шоке *2022-06-03* Решила учить математику во взрослом возрасте, в школе вообще ничего не поняла. Это приложение просто невиданная находка, за час разобралась чего конкретно от меня хотят эти числа🤣степени такие прикольные, сейчас разберусь куда факториал применить и всё решу) спасибо Вам! ### 5/5 — 好玩 *2022-05-28, version 1.22* 真的好玩 ### 5/5 — Absolutely phenomenal, and without ads! *2022-03-05, version 1.22* Horus International : Mathematics :: Zach Gauge : Words. This serves up some delectable mathematical exercise without the surreally strange functions of Devil’s Calculator. ### 5/5 — Good game *2021-10-30, version 1.22* Worth downloading for people who like math. Fun to use in downtime. ### 5/5 — 현존하는 최고의 게임 *2021-09-24* 화려한 그래픽도, 손에 감기는 조작감도 없지만 한 번 빠지면 헤어나올 수 없는 엄청난 중독성. 풀릴 듯 안 풀리는 문제는 버스에서 내릴 정류장을 놓치고 침대에 누워서 한참 동안 잠에 들지 못하게 하는 부작용이 있긴 함. 갤럭시로 갈아타고 나서 아이폰을 그리워하게 되는 유일한 이유. 널리 퍼져서 유클리디아처럼 데이터 저장 기능도 생기고 안드로이드 앱으로도 출시되었으면 하는 간절한 바람. ### 5/5 — Отзыв на приложение Tchisla *2021-08-04* Приложение великолепно ### 5/5 — Addictive *2021-06-12, version 1.22* Addictive. Simple, effective user interface. Free. No ads. I think I’m happy that it doesn’t tell you the optimal count unless/until you achieve it. I suppose I could dream up some bells and whistles to ask for, but it seems nearly perfect as is. ### 5/5 — Incroyable *2020-09-26* Simple à prendre en main et addictif, on a envie de trouver l’astuce suivante à chaque instant. ### 5/5 — Bon jeu *2020-08-02* Addictif... il faut se creuser la tête ## Most critical reviews (10 lowest-rated) ### 1/5 — Позор *2025-08-16* Ну выключите уже остатки своих серверов, которые не справляются с оставшимися клиентами. Как говорила бабушка, не можешь cрать - не мучай жoпy. И попрощайтесь достойно с оставшимися юзерами, а не как сейчас. ### 2/5 — Great game but keeps crashing *2025-08-28, version 1.22* I love this game and spent a lot of time playing it several years ago (pre 2022, probably)! I just opened it back up again, and it has crashed at least 4 times in the last ~10 minutes. This is a pretty big issue for me as, after it crashes, I will have to remember and find the number I was working on again (and all the sub numbers I was working on in the progress of working on that number) ### 2/5 — Update revoked yellow marks on solutions *2025-05-22* When swapping the phone and redownloading Tchisla from the App Store some of my 1#x Solutions (namely 2,3,4 and 9) are now considered non optimal (using the dullest two digit solution X/X) which is very irritating to say the least. Unless you hit the rounding error by stacking several dozen square roots I don‘t think there is a more optimal solution. ### 2/5 — Потеряны результаты *2024-11-25* После вынужденной переустановки приложения мои результаты не подрузились из аккаунта Game Center. Было решено невероятное число задач с золотом. Хотя бы взять тот факт, что до 200 для всех цифр были золотые решения. Вся база решений утеряна. Поддержка даже не ответила. Интерес к игре потерян. ### 3/5 — Great but No Support? *2025-05-29, version 1.22* Fantastic game for those that like the puzzle. But recently it seems the server isn't working for the daily "contest" puzzle. Either your number will be recorded wrong (I'll routinely have it say "your result 60, at time of contest close 62" it's always +2 for some reason) or it won't be recorded at all. Just stays at "-" I play this game every day for years. Just takes a few minutes for the daily puzzle and then on to other things. Please update this issue. ### 3/5 — Вылетает *2024-05-18* Отличная игра, но на IPhone 13 вылетает каждый раз, когда вводится «золотое» решение с наименьшим числом цифр, что немного портит геймплей( ### 3/5 — Doesn't make any sense *2022-02-18, version 1.22* I wanted to like this game but I literally got stonewalled on the third tutorial level. At first it gave me purple diamonds with exclamation points, which I guess means I did it wrong. But then I put in equivalent length equations which I guess means I did it "right". But even then, it would force me to come up with more and more answers on the same single level. I had a stack of like 6 equations on that single level and just gave up. I have no idea what it was looking for and there is no tutorial to explain this behavior, either the purple diamonds or the stacking and stacking of more expected answers on a single level. ### 3/5 — Дайте возможность убрать подсказки, справьте выражения. *2021-05-06* Голова и так не варит, да ещё эти подсказки.. Я так совсем думать разучусь. 1=1 и этим сказано, а здесь ошибка выпадает, так вы сделайте приставку #выражения на конкретнее число 2#7|1 ? Я не понимаю что это значит просто 1 ? так же из-за этих подсказок думать вообще нет желания и тем более считать, 1=1 так это является ошибкой... •как это может быть в природе? тогда надо написать выражение 2#7= как здесь можно 2 выразить через 7 ? Здесь же вы предоставили возможность выбрать /14, это будет являться ошибкой поскольку 14 не является 2. Мне думается именно в визуальном соотношении это надо рассматривать, ошибок нет, но состав на мой взгляд плохо реализован, я не понимаю примера "1=" Это что значит? Тогда как надо выразить это через 7? Тогда надо писать что 1#7. 🦆 ### 4/5 — Не хватает *2017-06-08* Мне не хватает синхронизации решений: телефон периодически сгорает, после чего восстанавливать все результаты умственной деятельности кажется чем-то немыслимым. Можете за счёт моего iCloud, за счёт Game Center — чего угодно, пусть это будет. И ещё мне не хватает множественности решений: 2+2=2*2=2^2. В остальном всё отлично. ### 4/5 — Nice game *2017-03-07, version 1.22* I have played number puzzles before, and really like this one because I can do one or two and put it down. Or stay a while and play at one or another for a shorter solution. It would be better if I could see some of my previous ideas. ## Most praised reviews (10 highest-rated) ### 5/5 — Great puzzle, could use more gamifying *2025-10-04, version 1.22* I love all the apps from this developer. I love math puzzles because they’re a great brain workout. And Tchisla, like Euclidea and Pythagorea, have a beautiful design! I do wish they had some sound effects though. It sounds silly, but it makes a world of difference to complete a puzzle to a little magical chime as opposed stony silence. Make it a bit more “game like”. An example would be the app “Eat Pi”. Just some optional sounds would make a world of difference, also when it gives me some text to read, I sometimes don’t notice it because there is no “text pop-up” sound. Highly recommended app. ### 5/5 — Amazing *2025-06-21, version 1.22* Amazing game but how do you do 3 # 1 better that 3/3? Is it a mistake? Please tell me if it is 😭 ### 5/5 — 🔥 *2025-02-15* 2 через 9: факториал квадратного корня из 9 разделить на квадратный корень из 9 👌🏻 ### 5/5 — great *2024-12-05* I downloaded every of their app like pythagorea and pythagorea60 or even euclidea and they are all very cool and the problems are interesting. This app stands out from their other apps because it uses numbers instead of geometrical figures and the puzzles ar entertaining. ### 5/5 — Excelent *2024-07-12, version 1.22* Excellent game by an amazing company, please leave your products on the app store forever. I'd like a harder mode for gallery where the hidden base 10 centric concatenation operation is turned off, and perhaps an extra hard gallery as well with factorial and square root single operation disabled. I'm kind of amazed at how few of the puzzles need you to outside the 1 to 100 range as part of the optimal solution. It certainly makes you appreciate how 2 (1 + 1) and 3 (1 + 1 + 1) are nearly all you need. ### 5/5 — fun *2024-07-09, version 1.22* even the lowest rate is a 3 star！ ### 5/5 — Классная игра *2024-05-31* Много лет играю. Золото везде кроме задачи 8984#7. Нужно решить из восьми 7. Решение имеется, но приложение его не принимает. ### 5/5 — Fun! *2024-01-01, version 1.22* Good for people who like math ### 5/5 — Great *2023-11-24, version 1.22* Very fun arithmetic game. It kind of bothers me how you can do square roots and factorials for free, but not say cube roots or logarithms, seems arbitrary. Still 10/10 though ### 5/5 — Mysterious and awesome *2022-12-06, version 1.22* HIU makes the most elegant teaching / brain training apps I've ever seen. Really unique company, and I pray they continue to make more in the future. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
