The main game of “Tongtong Countryside” is a simulation-style progression experience centered on farm cultivation and low-carbon sustainability. You complete daily tasks to earn “Carbon Energy,” convert points into growth power for your crops, and sow four designated types of seeds in your fields, advancing through staged growth with harvest animations and sound effects. A leveling and rewards system, together with an honors system (medal wall, certificates, etc.), supports ongoing mastery and retention. Uniquely, the game adopts a public-interest mechanism—“you contribute points, and China Unicom donates to projects”—linking your low-carbon actions to real rural initiatives and making every interaction more meaningful.
