### 5/5 — Enfin un vrai jeu de maths!

*2020-01-28, version 1.1.4*

J’adore.
Par contre semaine 23 ça me mets toujours « vérifier votre connexion internet » et je ne trouve pas d’autres semaines pour un jeu sorti il y a 3 ans, serait-ce arrêté mi 2017?
Y’a une erreur dans l’énoncé de la semaine 15

### 1/5 — I like it but...

*2018-09-29*

I like this app a lot so far, but the multiple choice answers for 20 don’t match with the question. The answer has to be a six digit integer and the only possible answers given are 1 through 6. I’m confused about maybe what it is I am missing?

Also, on question 18, it is not specified if placement of the squares and where on the paper they are cut from makes a difference in different ways to cut out the squares.

### 5/5 — Ludique

*2017-02-25, version 1.1.4*

Faire des maths en s'amusant ! Défis variés. Ça stimule les neurones.

### 1/5 — Appétissant mais après 3 bouchées (=défis) plus rien à manger

*2016-11-10, version 1.1.4*

Application payante ... Juste 3 défis gratuits , histoire d'appâter le joueur . J'efface l'application de mon téléphone, dommage .

### 4/5 — Très bonne idée, dommage que ce soit payant

*2016-10-24, version 1.1.4*

Aurait pu être parfaite

### 2/5 — Bonne app mais vite payante

*2016-10-24, version 1.1.4*

App intéressante mais payante au bout de quelques défis. Dommage !

### 2/5 — Super mais dommage

*2016-10-21, version 1.1.4*

C'est super de faire des maths en s'amusant, mais 1€ le défis c'est abusé !

### 1/5 — Trop vite payant

*2016-10-19, version 1.1.4*

On résout 3 énigmes et il faut payer :-(

### 5/5 — Sympa

*2016-08-01, version 1.1.4*

De bons exercices, certains faciles, d'autres pas évidents, on peut y passer du temps... C'est sympa, j'ai hate de voir les prochains défis.

### 5/5 — J'adore ! Mais...

*2016-07-06, version 1.1.4*

J'adore c'est ce que je recherchais :) mais dommage que c'est payant
