Money Guide: Base Slots, Selling, Offline Income and Number Suffixes

How income works

Each animal on your base pays a fixed amount per second. That amount is set by the species, its mutation and its size. The zone it comes from matters most: a plain animal from a new zone usually beats a heavily mutated one from the previous zone.

Only animals placed on your base earn. Animals in the backpack earn nothing – with one exception: the percentage-based egg animals (Pumpkin Monster, Fairy Fox and the rest) look at your best animal even if it is sitting in the backpack.

Base slots: 10 → 20

You start with 10 base slots. The plot upgrade adds more, up to a maximum of 20. Each upgrade is cheap compared with what one extra animal earns, so buy them as soon as they are available.

Use “Equip Best” whenever you catch something new. It sorts your whole collection and places the top earners on the base.

Selling animals

Open the sell menu (backpack) to sell animals you will never use again. The refund is small – selling a full inventory of old animals might return a fraction of a single food purchase – so treat selling as inventory cleanup, not income.

Keep anything you want in the index. The index tracks what you have caught, not what you currently own, but there is no index reward, so it is purely a collection goal.

Offline income

Your base keeps earning while you are away. When you come back, a popup shows what your animals earned offline (for example “Your animals earned 766K offline”). The 2x Cash pass doubles this too.

Before logging off, always run Equip Best and fill every slot – the offline payout is based on the base you leave behind.

Reading the numbers

Cash and income use short suffixes. Each step is 1,000x the previous one. The full table is on the Economy page; the ones that confuse people most:
