### 3/5 — Good version of this puzzle

*2019-01-08*

Would be even better with a back-track / in-do feature. And without the random resets where a partially solved puzzle is lost.

### 4/5 — Keine fünf Sterne...

*2018-06-21, version 4.1*

... obwohl mir das Spiel wirklich Spaß macht. Und eigentlich sollte man bei einem kostenlosen Spiel nicht über die Werbung stänkern, aber wenn selbst bei deaktiviertem Ton UND auf Stumm gestelltem iPhone die Werbung in voller Lautstärke läuft dann geht irgendwas gewaltig schief!!!
Daher ein Stern Abzug wegen der Lautstärke!

### 1/5 — Mathematical nonsense

*2015-10-17, version 3.1*

This game could have been mathematically programmed by a 10 year old. The maths in the riddle are just to poor and lead to non-unique mathematical solutions, despite buying the upgraded version.Moreover, even larger riddles restrict to mere addition tasks which is a tedious and more importantly boring way to spend time. Do not buy this game unless serious coding updates  have been performed.

### 2/5 — Fun game, but unfinished app

*2015-07-22*

There are no transitions between menu screens (just cuts from one to the next), most of the icons at the top of the screen are not clear about what their functions are (both in game and main menu), locked items do not specify that they are in-app purchase items, or how much they cost to unlock.

### 4/5 — Handhabung zu umständlich

*2015-05-26, version 3.1*

Im Gegensatz zu anderen Mathdoku-Apps im Appstore bietet diese App zwar eine Notizfunktion und eine Fehlererkennung, aber die Handhabung ist ziemlich umständlich. Jedes Mal, wenn man zwischen Notizen und richtigen Einträgen wechseln will, muss man oben rechts in der Ecke noch ein Feld anklicken.. 

Verbesserungsvorschlag: 
- entweder 2 verschiedene Ziffernreihen von 1 bis 9 anbieten, wovon eine für die festen Einträge ist und eine für die Ziffern oder die App so einstellen, dass man mit dem Antippen einer Ziffern einen Eintrag macht und mit dem Antippen mehrerer Ziffern im gleichen Feld Notizen macht. 

Wenn ihr das noch irgendwie optimiert, gibt es von mir 5 Sterne.

P.s. Und bitte erhöht die Schwierigkeitsgrade. Auf dem iPad würden sich auch größere Felder (zum Beispiel 16x16) anbieten, damit man sich mal über eine kleine Herausforderung freuen kann ;-)

### 5/5 — Best version

*2015-02-12, version 3.1*

Easy, smooth, visual.
Only 99p to unlock all sizes.

### 1/5 — Most content locked

*2014-09-11, version 3.1*

Only grids up to 5x5 are free the rest are locked. I only like to play 8x8 or 9x9  so not really good for me. They should have a few free games on each level so if you like it you can pay for more levels once you've tried out the game. Oh well!

### 5/5 — Ben fatto

*2014-05-21, version 3.1*

A me piace, lo consiglio !!!

### 5/5 — Bello :)

*2014-05-20, version 3.1*

Bel gioco

### 5/5 — Bel passatempo

*2014-05-20, version 3.1*

Consigliato !!!
