### 5/5 — Brain Training Galore. No annoying ads.

Minimal ads, plenty of killer sudoku games.

### 5/5 — Mrs

*2025-10-22, version 1.3.7*

Love it

### 5/5 — favourite dev, i would eat puzzles for breakfast if i could

*2025-09-25, version 1.3.7*

i'm gonna be so real, the guy who made this as well as their other games is one of my favourite app devs. what they make is honest, helpful, fun, easy to navigate, the ad prevalence is incredible (especially since it doesn't shove anything in your face and the ads rather show up at acceptable and expected times), and everything functions so smoothly. 

i got my dad into their nonogram app and he's been really enjoying it, i just got killer sudoku and told my dad about it as well- i am so excited to get started

### 5/5 — Challenging, ad free!

*2025-04-11*

Stumbled across “killer sudoku” after years of sudoku. The additional logic involved is a great dynamic. The developers offer this package ad free. Kudos.

### 5/5 — Best killer app

*2025-02-06, version 1.3.5*

Ive downloaded so many and they were laggy and nv had a daily leaderboard. This js hands down the best.

### 5/5 — Nice Killer Sudoku

*2025-01-31*

This is the premium of several KS games offered. It’s simple, practical and lets advertisers off easy.

### 5/5 — The best Killer Sudoku app out there!

*2025-01-19, version 1.3.5*

From UX to Evil levels to Trophies, its all you need.

A request: can you add an Auto-Complete feature please!

### 5/5 — Судоку

*2024-08-08, version 1.3.1*

才刚开始玩杀手数独，选中格子能计算总和的功能太好了，随便下了三个，别的app没有这功能，也没有精力慢慢去试更多app。很多题目是对称的耶…感觉有筛选过（？），新手感觉困难等级到专家等级难度骤增

### 1/5 — Why Advertising?

*2025-05-28*

Should be a relaxing game. But with ads while playing it is very inconvenient.

### 1/5 — Adds

*2024-06-13, version 1.3.1*

Adds

### 1/5 — Terrible Translation

*2024-01-27, version 1.3.1*

I’ve uninstalled the game immedaitely after installation. Absolutely disgusting and unfriendly translation to the Czech language without possibility to switch into English. Probably automatic translator? It is unplayable. Tranlations should be done by people who understand the language otherwise is better to not translate the game. Maybe it could be a good game but for me it is unplayable

### 1/5 — Обновление отстой

*2024-01-07*

Невозможно жирные цифры. Раньше было оч гармонично все. Нового дизайнера на мыло и продуктового туда же.

### 1/5 — Does not adhere to soduko rules

*2023-05-22, version 1.3.0*

Should have only one solution. This forces errors for for invalid Sodukos.

### 2/5 — FIX!!! Please

*2022-12-09, version 1.2.9*

Please fix.  The dashed lines that outline the sum you’re attempting to fill ARE TOO LIGHT.  Please make them bolder.  I’ve played about 250 of these puzzles and it’s VERY frustrating.   Update and fix

### 3/5 — Loved this app but now it’s letting me down :(

*2025-08-02, version 1.3.7*

I’ve really loved playing Killer Sudoku at its highest level on this app, but lately several of these games I’ve taken on have had obvious errors - really disappointing

### 3/5 — レビューをみてインストールしてみました

*2023-03-03, version 1.3.0*

他のキラーナンプレアプリをやっています。

入力の際に数字の上をスワイプするだけでは入力されず、一々個々の数字をタップする必要があるのが面倒に感じ１つも解かずにやめてしまいました。

撫でるだけで入力できるようになれば最高です。

### 3/5 — Leider nicht auf dem Kopf spielbar

*2021-08-14*

Leide kann man die App nicht benutzen, wenn man das iPad lädt. In dem Fall dreht man es normalerweise auf den Kopf, so dass das Ladekabel oben ist. Die App dreht sich aber leider nicht.

### 4/5 — 連続数字が入れづらい

*2024-09-12, version 1.3.3*

12345、、と言うように連続して1マスにメモを入力するとき指をスライドさせて一気に入力できないのが難点。他の機能は特に問題ない

### 5/5 — Non-intrusive ads, big range of difficulty levels

*2026-07-22*

Uninstalled other killer sudoku apps because the ads made it a horrible experience.  I hope they keep the ads as they are - a small banner at the bottom and short pop-ups after you finish.  The range of difficulty is also good, though it is a big jump between medium and hard settings.

### 5/5 — Solid

*2026-07-18*

Better than the other options out there.  Less annoying ads and solid gameplay

### 5/5 — Great game

*2026-06-18*

I enjoy playing killer sudoku it is challenging and help me pay attention to all directions of the board at the same time.

### 5/5 — Very good game

*2026-06-13, version 1.3.7*

Easy to use, good game

### 5/5 — Нравится

*2026-04-30*

Очень нравится, что есть реально сложные уровни

### 5/5 — Great functionality, no ads!!!!

*2026-04-08, version 1.3.7*

No ads!! Exactly what I was looking for after the Sudoku.com version wouldn’t let me go more than 2 mins without blaring technicolor ads. This one has all the same functionality (number first selection option, static grid guesses instead of the numbers moving). Only wish is some slight color/design adjustments for better legibility, but it is so beyond preferable to the ad slop or horrible interface from every other version.

### 5/5 — Судоку

*2026-03-02*

Мне нравится эта игра, она реально на поддержание интеллекта в тонусе, а не тупое нажимание на кнопки. И спасибо, что без рекламы. Вечно она сбивала с толку.

### 5/5 — Good game

*2026-02-24, version 1.3.7*

Played this for a few days and all is working well. The levels are a good mix and the daily challenges are great too.

It all just works and the ads are not intrusive being between games. The only improvement I would like is for the advertising close button to be on the edge not in the middle.

### 5/5 — Best Killer Sudoku app

*2026-01-16*

It’s functional, takes up low space, and four of its nine difficulties are cages-only.  Id be hard pressed to find a better killer sudoku app.  It also has hints if you prefer to play that way

### 5/5 — Best one going

*2025-12-01, version 1.3.7*

I’ve tried them all. Either horrid adverts or no auto-fill of notes. Whoever wrote this program is a genius!
