Our new Blockly Intro Course has landed! And it's free!

Not Just Coding: A Mystery Adventure in Blockly!


Last year, we launched our Introduction to Python course — a free, narrative-driven experience where students learned core programming concepts.


Today, we are pleased to anounce the release of its Blockly-version for upper primary students. The Blockly course closely mirrors its Python sister, allowing educators to provide an earlier entry and a levelled learning experience to their students.


Introducing Cyber Mystery: AI & Coding with Blockly

Cyber Mystery is a free, browser-based course designed to teach students in Years 5–6 the fundamentals of Blockly coding through an intriguing, story-driven mission.


🧩 Engaging Student Activities

The activities are crafted to challenge students to:

  • Use Blockly to interact with and repair a mysterious system.

  • Apply coding concepts like `print()`, `input()`, variables, decisions and loops through immersive problems.

  • Encode information in a binary matrix.

  • Hack an Artificial Intelligence (a simple neural network - safe for students)


🎮 Where Story Meets Syntax

In this engaging course, students don’t begin with a simple “Hello World.”

Instead, they uncover a strange program on the school server. With each discovery, they awaken a dormant system. In order to get repaired, the system teaches students how to code. Once repaired, the system tries to leave the school server and take over the internet - oops!

We added a super-sleek and easy-to-use Blockly Editor with runtime code highlighting, code checking, variable monitoring and solution-guided code feedback.

Along the students' journey, we placed plenty of quizzes and mini-challenges, spiced up with cinematic videos and cool music.


What starts as a routine repair job quickly transforms into an epic awakening...


Oops, we've unleashed an AI. Better fix this.

The final twist? A dramatic endgame that is worthy of a storyline that blends the worlds of The Matrix and Terminator.

Rank progression and badges 🎖️

As students demonstrate mastery of key concepts in the mini-challenges and the endgame, they unlock ranks and collect badges.

Rank progression is persistent, meaningful, and tied directly to mastery — giving students a strong sense of momentum and achievement. The rank carries across to the award ceremony where we print it on the student certificate.


Multi-Language support 🇦🇺 🇩🇪 🇫🇷 🇪🇸 🇨🇳

The course is available in English, German, French, Spanish and Mandarin, supporting a wide range of native language speakers. Or just use it as a different way to teacher LOTE.

Teacher Support

The course contains a central info page for teacher, as well as solutions and explanations for every coding challenge, directly baked into each task, only visible to teachers.


How to get started

The course is free but anonymous student accounts are required, so that students can collect points and badges, receive a certificate and for teachers to track student progress.


  1. As a teacher, log in to MyComputerBrain (or create a teacher account)

  2. Head to the Shop and create free student accounts for the Cyber Mystery Course. No payment details are required.

  3. Distribute the login/password combinations to your students and have them log into MyComputerBrain.

  4. Students see their licensed courses directly on the homepage.


Our serious commitment to student privacy is on record here.


👩‍🏫 Designed for Real Classrooms

This course is:

  • Free for all learners.

  • ✅ Aligned with the Australian Curriculum v9.

  • ✅ Suitable for Years 5–6, requiring no prior coding experience.

  • ✅ Fully online—no setup or installation needed.

  • ✅ Hands-on, featuring activities, mini-challenges, and quizzes.

📚 Prepare Your Students to Code

Give your students the Blockly course they won't forget. Engage them with a one-of-a-kind learning experience that sparks their curiosity.


The BIGGER Picture.

The Cyber Mystery course can be the beginning of a fantastic learning journey for your students. Once they have completed the course, they can continue with the Python intro course, and from there do the Academy of AI Cyber Defence. These are three free and highly engaging courses that are designed to work well together.
