## Most critical reviews (10 lowest-rated)

### 1/5 — Waste of money, possibly a scam

*2021-07-18, version 2.0.2*

There are NO instructions on how to play. Nothing at all. I can’t believe it. Even searched the web, and nothing. Too bad I have already paid for it. I think this is a scam

### 2/5 — Rules?

*2021-09-20, version 2.0.2*

How is it played? It looks interesting, but I can't play it without rules!

### 4/5 — Challenging and fun

*2024-09-30*

Way better than I had expected! This game keeps me brain elastic fer sure!

### 4/5 — Great app but no mode description

*2017-11-03*

This is a very calming app which makes you think but would be nice to add descriptions of each game mode because you cannot tell what the rules are just by looking at the icons.

### 4/5 — Found the instructions!!!

*2017-10-28*

This is a second review. My original was based on somehow missing the instructions and not being able to make sense of the game. As a Sudoku fanatic I expected similarity where very little exists but when I got an inkling of the game I enjoyed playing it and when I found and read the instructions I got hooked on it. Yeah, sometimes I just randomly try things but when I start shuffling things around with a purpose the game gets interesting and challenging. I really like it.

**Developer response:** Hi Pete, this is Dave, the developer.

There's an extensive tutorial that shows how to play. The tutorial starts automatically on first launch, or you can rewatch the tutorial by going to Settings|Tutorial. Tap the arrow buttons at the bottom of the tutorial screen to move through each step.

The quick explanation is this: There are core tiles (the red ones with two numbers), and outer tiles (the gray ones with a single number that surround the core tiles). The top number on a core tile shows the sum of the numbers on the outer tiles. The bottom number is the sum you need. You move tiles around by tapping any two outer tiles on the board, causing them to swap places. The sums for each core tile will then recalculate and any that now match your target sum will turn green indicating it's correct. Repeat until all of the core tiles are green. The first core tile is the easiest, but it gets harder for each of the remaining ones. Sometimes you'll have to break a core tile in order to solve the whole board. Every board has a solution. The small/easy boards can usually be solved in 1-10 minutes. The larger/harder boards can take longer.

I hope you revisit the game and give it another shot. If there's a way I can make it easier to understand how to play, please let me know. I'd really like to earn your 5 stars. :)

Thanks!

### 5/5 — Straightforward strategy

*2025-02-22*

Great fun twist on a sudoku like game.
Did a great job with aesthetics and difficulty progression.
For those who like Rubik’s cube and sudoku?”, it is worth a try

### 5/5 — The Simplest Things are Often the Best

*2022-02-27, version 2.0.2*

Fantastically addictive. The challenge of developing the most efficient approach is most enjoyable. I will be spending much quality time with this app. Many thanks to the developers.
Kudos.

### 5/5 — 解けた時の達成感

*2021-04-02, version 2.0.2*

あちらを立てればこちらが立たず、一番簡単なサイズの盤面からしてかなりアタマ使う感じです。なんかルービックキューブ解いてるみたいな…
それだけに解けた時はかなり気持ちいい。広告もないっぽい？し、操作感も良い。オススメのパズルゲームです。

### 5/5 — 並べ替えパズル

*2021-03-28, version 2.0.2*

指定数に合うように数字を並べ替えるのが、これまでなかったと思います。
好きなところを入れ替えられるのでやりやすいです。

### 5/5 — Fantastic app

*2020-12-24, version 2.0*

If you like sudoku, you’ll love this loo!

### 5/5 — Simply the Best!

*2020-11-03, version 1.1*

Simply the best puzzle game! Easy to understand but challenging to play. Different levels of difficulty means it can fit you easily and allow you to progress. Pleasing haptics and visuals. Why are there so few of us Rudokuans, I do not know, but we are a happy, peaceful and prosperous land!

### 5/5 — Entertaining number puzzle

*2018-02-02, version 1.1*

Good fun, can make it as simple or large and complicated as you want. Really good puzzle game.

### 5/5 — Addictive!

*2015-11-15, version 1.1*

And no in-app purchases, thank you.
