Coins and Sinks

Spend coins on more raise slots, a new mutation or a hatch boost. Every price is a share of your next rebirth cost, so it grows with you.

Raise slots

Every player has 5 raise slots. You can buy more, up to 30. Each slot costs 1.2 times the one before. See Pet Levels for raising.

Mutation Lab

The lab costs 20% of your next rebirth. It uses up the pet and one copy of the same pet. The pet comes back with a different mutation. Rarer mutations are less likely.

Hatch boosters

A booster raises your luck for rare eggs. Buying one again refreshes the timer and does not stack. Both boosters together add up.
