Best Slime Games Online: Merge, Grow and Fight

Squishy, bouncy and oddly satisfying, slimes are stars in many browser games. Merge them into new forms, raise them on a farm, eat everything in sight as a growing blob or fight off slime hordes. Here are the best free slime games to play now.

What makes great slime games?

Slime games are relaxing because growth is so visible. Two slimes become one bigger slime, a small blob swallows a whole field, and coins pile up in clicker games. The best ones add collections with many forms to unlock, which gives you a reason to play one more round.
