## What is Chemtrix?

Chemtrix is a fun arcade style puzzle game where your goal is to build molecules to progress through the game. There are 24 levels to work your way through, and on your journey you will discover the deepest secrets of the universe - how atoms bond and the structures and properties of the molecules they form.

You can also play in 'free fall' mode, where new atoms drop continuously into the game board and your goal is to keep building molecules until you out of space.

This is a fun game informed by real chemistry, the molecular structures you create and the way the atoms bond to each other are true to life. And extra features like lewis-dot notation and accurate energy calculations will delight discerning chemists.

### 4/5 — Great concept, but confusing

*2024-10-20*

Excellent concept. I introduced this game to my child, but found that the meaning of moving dots is confusing, e.g. C has 4, but O has 2. My kid thought that the dots are electrons.

### 5/5 — The

*2021-09-25, version 1.3.8*

Cool,huh?

### 5/5 — Just getting started

*2021-09-23, version 1.3.8*

Was looking for a chemistry game with lessons/tips. This is a great start! Except I’d like it better if I could adjust the speed slower. Thank you

### 5/5 — Hi guys I love this game so much

*2021-02-05, version 1.3.8*

Thank you chemistrix for making me so happy I appreciate it I’ll play all the time

### 3/5 — Intéressant

*2021-01-27, version 1.3.8*

L’idée de cette app est de simplifier la chimie au maximum. Il y a un problème de traduction en français, c’est probablement une traduction automatique. L’ergonomie générale est déconcertante et le contenu est léger. Il y a des erreurs qui peuvent plus ou moins être mises sur le compte de la simplification. 
Le montant de l’achat in-app n’est pas exprimé en euro.

### 1/5 — Fun and educational

*2020-10-31, version 1.3.8*

Very good idea and well designed 
Main issue : I’ve done the free 9 levels but can’t go to 10. I’d pay but I get no prompt for an in-app purchase ... just stuck .. am I missing sthg ?

### 4/5 — Awesome

*2020-08-29, version 1.3.6*

This app is so helpful for kids who just started learning about the periodic table. This is a very creative app and so much engaging. I think learners from grade 8, 9 and 10 will benefit a lot from this app. The only thing I would change is to give the levels a time limit, so learners know if their doing better or worse every time. I would’ve loved it if an option was given to choose from like giving the name of the structure given or vise versa. But thanks a lot for a great app. Very helpful!
