Chromecreatures

ChromeCreatures hides a creature collection game inside your normal browsing.

While you go about your day, checking emails, reading articles, scrolling the news, creatures spawn on the pages you visit. A rare one might appear on a finance page. A common one might be lurking behind a product listing. You never know where they'll turn up.

When one appears, click it to start an encounter. Battle it in a separate tab, then attempt a capture. Each creature has its own rarity, behaviour, and home turf. Some are far more likely to appear on specific sites, others only come out at certain hours.

Features:

Creatures appear naturally while you browse, no grinding, no dedicated play sessions required
Six rarity tiers: Common, Odd, Unhinged, Cursed, Forbidden, and Classified
Page-aware spawn rules: different creatures favour different kinds of sites, topics, and browsing contexts
Work mode: one tap to pause all spawns when you need a distraction-free screen
All game state lives on the server, your collection is safe across devices and reinstalls
Requires a free account at chromecreatures.co.uk to link the extension and start collecting.
