Sloth Evolution: Merge Game

Sloth Evolution: Merge Game is a playful Chrome extension that lets you merge mutant sloth species to create surprising new breeds. Drag and drop similar sloths to evolve, earn coins, and unlock more creatures as you progress. You can discover whether sloths become loving pets, expert climbers, or efficient trackers in this slow-blooming adventure.

With doodle-like illustrations, open-ended gameplay, and a quirky story with twists, this idle–clicker mashup combines elements of evolution and incremental games. Highlights include multiple stages, an evolving cast of sloth species, and playful features like Pantheon and Impostors. Note: while free to play, some content can be purchased in-game; turn off purchases in your device settings if you prefer.
