### 5/5 — Very Addictive

*2020-03-05, version 1.2.0*

Didn't think I'd like this game much, but I was wrong. Skill levels are at the right level for me. I can't stop playing. Only wish there were instructions. I have to figure out what the different the different symbols and scoring mean.

### 5/5 — Sudoku

*2020-01-25, version 1.2.0*

Great to get you thinking, love it.

### 5/5 — Good software interface

*2017-05-04, version 1.2.0*

The interface of this software is easy to use.

### 4/5 — Good game

*2015-11-24, version 1.1.1*

Very addictive I love plying to pas time but my complaint is losing so much points by clicking the wrong box I sometimes accidentally hit the wrong box meaning to hit the right and I lose a lot of points

### 3/5 — Sudoku

*2014-08-19*

Warum nur drei Sterne, ganz Einfach zu erklären. Das Spiel stürzt ständig ab und es werden einen die erzielten Punkte ebenfalls abgezogen. Ein Beispiel. Hatte bereits über 7,7 Mio. Punkte und laut Scorerliste auf Platz 343. und jetzt auf einmal drei Plätze stiefer und es fehlen die Punkte ????

### 1/5 — Poor entry system

*2014-07-05, version 1.1.1*

Why does highlighting go away when you go to pencil marks?  You need the highlights to know where to put the pencil marks. Duh.

### 5/5 — Very fun game!

*2014-03-13, version 1.1.1*

Very fun! Both my husband and I like it a lot!

### 4/5 — Great Version...

*2013-12-15, version 1.1.1*

...but like another reviewer, I have questions about the scoring. As one makes one's way through the levels, the overall high score seems to be tied to very easy levels; even a quick and faultless play at higher levels scores very low. Positively weird. In my experience, from playing it for quite a few months now, there is no way to get even close to early high scores, once you get to the harder levels. Perhaps scoring should be changed so it is just a person's high score in a specific level that is shown.

### 5/5 — Great app

*2013-08-19, version 1.1.1*

Great app

### 5/5 — Sudoku

*2013-07-16, version 1.1.1*

Love it!
