What it is
Blockerzz is a full 3D game platform for education that runs directly in the browser, with quiz-driven multiplayer games, maths escape rooms, creative building, and learn-to-code experiences.
Rather than treating educational software as something visually limited, it approaches the classroom as a place where game quality, technical ambition, and pedagogy can coexist.
Students can enter shared worlds instantly on ordinary devices, with no installs, which makes it unusually deployable in real school environments.
What makes it special
What makes Blockerzz special is the technical standard it sets. It delivers multiplayer 3D worlds, advanced rendering, and sophisticated interaction design in a zero-friction browser experience.
That combination is rare: high production value, strong educational utility, and infrastructure that still works within the constraints of schools and everyday hardware.
It expresses a particular belief I care about deeply, which is that educational products do not need to compromise on imagination, engineering quality, or craft.
What I did
Blockerzz began as a Christmas project: I wanted to see whether I could get a Minecraft-like game running in the browser. I personally implemented every line of code in the first version.
In the last year I have used AI coding tools to accelerate development while staying hands-on with the build.
Blockerzz is unique IP—a graphically rich block world environment that runs instantly in the browser on any device.
