### 4/5 — После обновления не влезает в экран

*2022-07-01*

Отличное приложение! Но после обновления интерфейс не помещается в экран ни на iPad Pro 11, ни на iPhone 11 Pro Max. Пожалуйста, поправьте!

### 5/5 — Brilliant!

*2017-01-02*

I have been a sudoku fan ever since I remember, and this incarnation of it is just hard to beat! Love the auto-suggestion to get the trivial numbers out of the way and let you focus on more challenging tasks. Night mode is so awesome for these long evenings when I keep playing it :) Highly recommended!

### 4/5 — Судоку

*2016-04-24*

Вроде неплохо, но как переиграть игру, в которой есть ошибки? Как сделать сброс?

### 2/5 — Чистка

*2016-04-14*

Если ошибся, приходится тыкать в каждую клетку и стирать по одной цифре до исходного состояния. Нельзя как-то упростить процесс?

### 3/5 — 3

*2016-04-11*

Нельзя очистить поле за один раз полностью от заполненных клеток. Очень не удобно
