MVIDIA: a free browser game betting you learn a GPU by building one
Solo developer Jaso1024's free browser game takes players from a single transistor toward a GPU — its Show HN drew 964 points on 2026-04-04.
MVIDIA
What the business is
MVIDIA is a free, browser-based educational game by solo developer jaso1024: cast as a new hire at a parody chip firm called Mvidia, the player wires NMOS and PMOS switches into logic gates, adders, memory, registers, an ALU and a programmable core, level by level, with tests on each build.
How it started
The author launched it with a one-line origin on Hacker News: 'Thought the resources for GPU arch were lacking, so here we are.' In the thread, Jaso1024 said games like Turing Complete inspired the idea but did not go deep enough and did not cover other processors, so he wanted to fill that gap and keep it free; the stack is Vite, React and TypeScript with Canvas 2D.
What happened
The Show HN on 2026-04-04 drew 964 points and 187 comments: commenters recommended it for students, learners said the visual, point-and-click levels made transistors click, and reviewers flagged bugs that the author fixed during the thread — a blank-screen level, a way back to a finished circuit, an optional truth-table round — while promising an optional Act 0 on transistor basics, mobile support and AI circuit hints. At the 2026-09-04 crawl the site still showed v0.1.0: Acts 1-3 playable (transistors to gates; gates to a core; programming the processor), with Acts 4-5 — The GPU and The Shader — 'coming soon'.
No ending yet — it is still running.
Background
MVIDIA is a free browser game by solo developer jaso1024, framed as a memo from the CEO of a parody chip company ('From transistors to teraflops') telling a software engineer they now work on hardware. The player wires logic from the ground up — NMOS and PMOS switches, NAND and XOR gates, adders, latches, DRAM, registers, an ALU and a fetch-decode-execute core — with every level tested before the next unlocks.
The bet is that people learn chip architecture by building it, not by watching it explained: the one-line launch post said resources for GPU architecture were lacking, and in the thread the author explained that Turing Complete-style games inspired the idea but did not go deep enough or cover other processors, so he wanted to fill the gap and make it free.
The Show HN on 2026-04-04 drew 964 points and 187 comments, with commenters recommending the game for students and learners reporting that the visual, point-and-click levels made transistors click. At the 2026-09-04 crawl the game remained free at v0.1.0: Acts 1-3 playable, with Act 4 (build the GPU) and Act 5 (program the shader) still listed as coming soon.
What has to be true
- Format first: interactively building a NAND gate or a DRAM row makes ideas that defeat slides — three-state logic, current flow, refresh — physically obvious, which is what commenters reported.
- Depth is the differentiator: going below the usual gate-level tutorials to actual NMOS/PMOS switches is what separated MVIDIA from Turing Complete and gave the thread its hook.
- Free and in-browser removed every barrier between a curious reader and the first transistor, which is how a solo launch could pull 964 upvotes and a 187-comment debugging session.
What can be applied
A 964-point launch proves hunger for hardware intuition, not a finished product: five months later the GPU its title promised was still 'coming soon'.
Aftermath
As of 2026-09-05, MVIDIA is still live and free at jaso1024.com with Acts 1-3 playable — transistors to gates, gates to a programmable core, and writing machine code — while Acts 4-5, 'The GPU' and 'The Shader', remain marked 'coming soon' and the page carries no pricing, team or company information beyond the author's @jaso1024_ account on X. The launch validated the appetite: 964 HN points and a thread full of learners and practitioners. Whether the game becomes a finished GPU curriculum, a paid title or a business was still undecided at the crawl.
