Grey-Box Testing

A mind-bending puzzle game where you probe digital systems, expose bugs, and verify hidden logic — all from your browser.

🎮 GREY-BOX TESTING — Play Free in Your Browser Step inside a hidden digital system where nothing is what it seems. Grey-Box Testing is a fast-paced puzzle game built in Unity WebGL, now available as a Chrome Extension so you can launch it instantly from your toolbar — no install, no loading screen delays, no sign-in. ────── ABOUT THE GAME ────── You are a tester with partial knowledge of the system — not enough to see everything, but enough to be dangerous. Your job is to probe the logic, trigger hidden states, expose bugs buried beneath the surface, and verify what no one else can see. Grey-Box Testing takes its name from software quality assurance methodology: grey-box testing sits between black-box testing (external observation only) and white-box testing (full code access). You operate in the grey zone — armed with just enough insight to challenge the system. ────── FEATURES ────── ✔ Full Unity WebGL game playable entirely in your browser tab ✔ One-click launch directly from the Chrome toolbar ✔ Fullscreen mode for total immersion ✔ Zero accounts, zero logins, zero trackers ✔ Link to full game collection at web-gam-dev.blogspot.com ✔ Puzzle mechanics that reward lateral thinking ✔ Dark, atmospheric visual style with WebGL 2.0 rendering ✔ Lightweight extension — all game assets run locally ────── HOW TO PLAY ────── 1.
