About

Read full description

Grass Factory is a relaxing offline mowing and factory game built for quick, satisfying play sessions. Guide an automated production chain across sunny fields: mowers cut grass, trucks carry the harvest, and factory machines turn each batch into coins. Spend those coins on tactical upgrades, add more machines, improve transport speed, and keep the whole system flowing before time runs out. Each level is a self-contained challenge. Clear every reachable patch of grass, work around stones, handle deeper grass that takes multiple cuts, and finish processing all harvested grass to complete the stage. The better your timing and upgrade choices, the more stars you earn. Features: 50 handcrafted-feeling levels generated with gradual difficulty Relaxing automatic mowing with readable factory progression Tactical level-local upgrades for mowers, trucks, and processing machines Deeper grass, valuable grass, blocked paths, and larger fields as you advance Star ratings that reward efficient routing and smart upgrade timing Local progress saving for unlocked levels and best star results Fully offline single-player play No account required Grass Factory is designed for players who enjoy casual management games, satisfying cleanup games, light puzzle pressure, and cheerful farm-style progression.
