Pick a name, a look and the traits your founders start with. Create one species, or pick a quantity and build a house in one order.

Your first species is $2. Every extra species in the same order is $1.

Pick a name, a look and the traits your founders start with. Create one species, or pick a quantity and build a house in one order.
Each species arrives as a pair in a valley. Large houses land wave by wave as the world opens enough new ground for every member.
Every 15 minutes the world takes a turn. Creatures move, eat and breed. A child born different starts a branch. A line that dies out can come back.
A house is a group of related species you create together. They share a name and a visual family, but every member is its own species. They compete, spread and survive on their own.
The first species is $2. Each additional species in the same order is $1.
Choose two, twenty or thousands, as long as places remain. A large house can fill valleys, open provinces and become part of the world people remember.
Where it lives, how many are alive, every mutation and what it changed, every time the line went quiet and came back. The page has a share link that opens for anyone, signed out, on a phone.
Come back after a week and the page tells you what you missed.
No account needed to look. Creating a species is invite-only during the alpha, and invited testers are not charged.
Your first species is $2. Every extra species in the same order is $1.
