Protect the Queen—grow your colony to 100 ants! "Ant's Diary" is a real-time strategy game where you raise an ant colony. Adjust the roles of your worker ants around the queen, survive enemy raids, and build a thriving colony of 100. 4 Roles to Strategize • Foragers (Green): Gather food on the surface and carry it to the nest • Nurses (Pink): Feed larvae to raise new worker ants • Soldiers (Red): Fight enemies and defend the colony • Digger: Digs to expand the nest — Completing rooms increases food and brood capacity Adjusting the balance of roles to match the situation is the key to survival. Nest Expansion & Chambers • Assign workers to digging and the nest grows organically from existing tunnels. Food stores or brood chambers form automatically as needed. • Chambers raise food and brood capacity. When food storage is full, foragers wait and automatically resume as soon as space opens. • Nurses carry eggs from the queen's chamber to brood chambers and bring food from storage. After 3 feedings, a larva becomes a pupa. Explore 2 Worlds • Surface: A dangerous world where you gather food and battle enemies • Nest: A safe haven to raise larvae and dig new chambers Defend Against Enemy Raids As time passes, enemy attacks grow fiercer. Build up your soldiers in advance to prepare. Score Attack Challenge Your time to reach 100 ants is your score. Aim for the fastest record and try again and again!
