Crumbongo

Crumbongo is a free, local Chrome browser game that turns the accessible cookie count of websites you choose into game currency. Check a site, harvest its accessible cookie count into your Cookie Jar, earn lifetime progress, level up and unlock new content. Spend your cookies on pixel-art cosmetics, new habitats and companions to build your own version of Bongo. Crumbongo also includes two playable minigames: Monkey Climb, where you collect bananas and dodge hazards, and Cookie Stack, where you catch falling cookies, build a moving tower and avoid bombs to earn extra rewards. The game is designed for quick, casual sessions directly inside a Chrome extension, with no account or setup beyond installing it. Everything stays local by design. Cookie names and values are never stored or transmitted, browser cookies are never modified or deleted, and Crumbongo uses no analytics, tracking, advertising SDK or gameplay backend. The result is a lightweight browser game built around an unusual mechanic: turning something normally invisible in your browser into a resource you can collect, spend and play with.
