What expansion is for
Expand the Base when lack of room would waste your next useful hatch. More spaces let you keep more Animals, but the purchase only helps when you have an Egg route and a collection plan to use them. Check your current capacity and the live expansion price before spending.
The public page does not state the starting capacity, expansion price, or how many spaces each purchase adds. Check the capacity and price in your current game. Write down what the display shows before buying if you want to compare the result. That is safer than following an old screenshot whose numbers may differ from your session.
If your Base still has plenty of space, you may get more immediate progress from an Animal upgrade or from improving flight reach. The game says upgrades boost income, while longer flights open better Eggs. Expansion solves a space problem; it does not replace those other parts of the loop.
Time the purchase around a useful hatch
Before flying to a new Egg, inspect your Base. If it has room for the expected Animal, you can attempt the trip and evaluate the hatch. If it is full or nearly full, compare the live expansion option with your Cash balance. You may want to make space first so a successful route can turn into an earning Animal.
Do not buy space only because a guide says to do so at a particular number of Eggs. Your own capacity display and next target are more relevant. A player who is still learning the first Egg route may have a different need from one collecting rare Animals in a farther area.
| Situation | What to inspect |
|---|---|
| The Base is full | Expansion price and the additional room displayed in game. |
| One space remains | Whether your next Egg route is ready and likely to be completed. |
| Several spaces remain | Animal upgrades or flight progress may be more urgent. |
| Cash is limited | Compare expansion with the income benefit of an Animal upgrade. |
Keep the collection productive
More spaces are valuable when you can fill them with useful Animals. After an expansion, hatch from a reachable Egg and compare the new Animal’s income. If it strengthens your collection, the extra room has served a clear purpose. If you cannot yet reach better Eggs, focus on a reliable current route or upgrade an Animal you already own.
The official description also says rare Animals earn more Cash and Animals keep earning offline. That makes room for a stronger collection potentially useful beyond the current session. Still, the public page gives no exact income per Animal or offline cap, so avoid calculating a guaranteed payback period for an expansion. Measure the live effect instead.
For the immediate problem of a full Base, read Animal capacity. To decide between space and earnings, see Animal upgrades and Cash spending.
FAQ
What does Base expansion do?
The official game description says it lets the Base hold more Animals. Check the live capacity display for the current increase.
When should I expand my Base?
When limited room prevents a useful hatch or your next planned Egg trip is likely to fill the remaining space.
How much does expansion cost?
The public description does not publish a price. Read the current cost in game before purchasing.
Does expansion increase Cash directly?
Its documented role is Animal capacity. Extra room may support more earning Animals, but check the live result rather than assuming a direct Cash bonus.
