Jeff's Cosmic Brew
Relaxing cosmic idle game
Free · In‑App Purchases
Upgrade, build, and grow from humble beginnings to universal success.
An alien named Jeff has a stroke of luck when an asteroid crashes into his garden. A fragment splashes into his drink and dissolves, turning it into the best thing he’s ever tasted.
With this new discovery, Jeff begins a journey of upgrades, refinement, and ever‑growing production.
This is a hybrid idle game, built to be relaxing, satisfying, and full of ways to keep you engaged. Grow from humble beginnings to a global - and maybe even universal - phenomenon as you unlock new boosts, push your limits, and watch your progress reach new heights.
