How to Expand Your Base in Climb For Animals Eggs

Expanding your base in Climb For Animals Eggs is a purchase, not a building project: you pay Cash for the base upgrade at your own base, and the added room lets you place more animals there. The game's official how-to-play list makes it the final step of the core loop — climb to new areas, train Speed on the treadmill, hatch Eggs, place Animals at your base to earn Cash, upgrade your income and upgrades, then "Expand your base to hold even more Animals."

In recorded play, the first expansion tier cost 1,000,000 Cash and took effect immediately: right after paying, the player went from a completely full base to "now I can place a lot here."

When you need to expand

Placed animals earn Cash continuously — including while you're offline — but the space to put them is limited. You'll notice the limit when you hatch a new animal and have nowhere to set it down. In one recorded session, the player placed a freshly hatched animal and found his base full on the spot ("my house became full"). An animal without a spot isn't earning for you, so expanding is how your placement count and your Cash income keep growing together.

How to expand the base

1. Keep animals placed and earning. The Cash that pays for expansion comes from animals already at your base, and they keep earning while you're offline.
2. Buy income upgrades first. The game's stated order is to "upgrade your income and your upgrades, then expand the base so it can hold more animals." A faster income rate is what makes the purchase price realistic — see our picks for the best upgrades.
3. Save at least 1,000,000 Cash. That's the first observed tier. In the recorded session, the player read the requirement at his house — 1 million needed, 7,000 in hand — so the gap is the grind. If you're short, our Cash farming guide covers faster routes, and it's worth a glance at the current codes before a long one.
4. Buy the upgrade at your base. The purchase happens at the base building itself — the recorded player calls it the "house upgrade" — and completes as soon as you pay. The exact button or prompt isn't documented, so look for the upgrade option at your base when you have the Cash.
5. Confirm with space. Success is visible immediately: after paying his 1,000,000, the player at once had room to add more animals.

One uncertainty worth knowing before you plan: it has not been confirmed whether the base must be completely full before the upgrade can be bought. In the recorded run it was purchased with a full base, but that may simply be when players first go looking for it.

What expansion costs

Only one figure is on record: 1,000,000 Cash for the first tier, seen in a single recorded playthrough. There is no official cost table — the game's public description lists no prices, and even the community wiki keeps none. Costs for later tiers are unknown, so treat every price after the first as unseen until you're standing at your own base.

Budget matters here, because expansion competes with other big spends. The same player who bought the base upgrade was saving 5,000,000 Cash for a treadmill upgrade shortly after, so decide what you need more: capacity or Speed.

How much space you actually get

No source publishes a slot count. The official description promises only that an expanded base will "hold even more Animals," and recorded play agrees in kind: after the 1,000,000 Cash upgrade, the player could place "a lot" but still noted he couldn't place "that many things" — capacity grows, but it stays finite.

Practically, that means you judge each expansion by what you can see in your own base: how many animals you can now set down before it fills again. There's no published number to plan around, before or after buying.

Expansion repeats

This is a recurring purchase, not a one-time unlock. As you hatch and place more animals, the base fills again — later in the same session, the player added another animal and checked his space ("this got full — no, not full yet"). Each time it fills, the same route applies: let placed animals build Cash, pay for the next upgrade, keep placing.

Putting the new space to work

New room only pays off once animals are standing in it, and every placed animal raises your income, offline included — see offline earnings for how that works while you're away. The placement steps themselves are covered in how to place animals.

Short version: keep animals earning, stack Cash to 1,000,000, buy the house upgrade at your base, and repeat whenever it fills again.
