How to play

Tap the world to release entropy. Spend it on nodes in the evolution tree — every node you own adds entropy per second, forever.

Nodes in a column unlock in order. The optional branches (Sexual Reproduction, Flight, Mathematics …) are not required, but each one multiplies everything you make. Buying them early is the only real decision in the tree.

Every discovery pays Insight. Spend Insight on permanent multipliers — they survive Metamorphosis. When you reach the end of the tree you can Metamorphose and start again with Ancestry, which is never lost.

Progress saves automatically and keeps running while you are away (up to the offline cap). Space bar also taps.
