Before you join
Does this install the game?
Join the group first, then opt in on Google Play and follow the link to install Idle Microbes. Use the same Google account for the group, Play opt-in and your Android phone.
What will you email me?
Beta invitations, test-build news and occasional Idle Microbes updates. You can leave the group or change your email preferences at any time through Google Groups.
Is the beta free?
Yes. Idle Microbes is free on Google Play. No purchase or promo code is required. Join the group and opt in to the closed beta to install.
Who can play?
You must be at least 13 and in a country where the beta is available. Anyone can join the mailing list. Installing the closed beta requires group membership and a separate Google Play opt-in.
Already using a test build?
If you joined the Play internal test, leave that test before opting into this closed beta. If you installed through Obtainium, back up your game save before changing installation channels; Play uses a different signing key.
