FAQ
What is Iawase?
Iawase is a cozy idle game where you hatch, raise, and collect voxel monsters. You feed them fruit from trees, watch them grow through ten stages, and discover new families. The game features idle progression, allowing your planet and companions to develop even when you're not actively playing.
How do I get new eggs in Iawase?
You can get new eggs in Iawase by having your companion reach stage six and then interacting with a stage-ten friend, which will cause an egg to appear. Additionally, a new egg may drop onto your planet by itself every two days. Building structures like houses can also help warm and hatch eggs.
Can I play Iawase offline?
While the core gameplay loop of Iawase is designed for idle progression, which continues when the app is closed, the game does require an internet connection for certain features like encountering other players' planets through Game Center.

Does Iawase have ads?
