My Billionaire Zoo Floors: Floor 2 & Floor 3 Unlock Costs

Each storey is bought with rebirth points, which is the same currency the Upgrade board spends. Here are the two prices that were on screen and the one storey nobody has shown yet. Checked October 14, 2026.

Floor costs read off the Floors menu

Rebirth-point prices for each zoo storey as shown in three dated creator recordings.
Storey	Price on the menu	What a recording showed
Floor 1	Unlocked from the start	The starting plot with its pens
Floor 2	100 rebirth points	Unlocked once on screen: a second storey with stairs, used for a Mythical Snaketrio
Floor 3	5,000 rebirth points	Never unlocked in any recording, so its contents stay unknown

One currency, two sinks: the Floors menu and the Upgrade board spend the same rebirth points. At 100 points, Floor 2 costs about ten times what Auto Roll costs on the board, and the board has five other upgrades competing for the same balance.

Walkthrough

Unlock a storey in the order the game presents it

Five steps. The decision step is the one that costs you something either way.

Read the requirement on the Floors menu itself

The Floors button sits on the left of the plot screen and lists each storey with its own price. Floor 1 reads as unlocked; the later storeys show the rebirth points they want on the button.

Check how many rebirth points you are holding

Rebirth points are the currency the rebirth reset pays out. The Floors menu and the Upgrades board spend the same pool, so the balance on screen is what decides which purchase is available right now.

Decide between the storey and the Upgrades board

Every point spent on a floor is a point not spent on Cash Boost, Multi Roll, Luck Boost, Gems Per Min, Rebirth Buttons, or Auto Roll. A storey buys space; the board buys rate.

Buy the storey and walk up the new stairs

In the August 15, 2026 recording, spending 100 rebirth points on Floor 2 raised a second storey with a staircase, and the player placed a Mythical Snaketrio on the upper display area.

Re-check the next storey price before saving for it

Floor 3 asked for 5,000 rebirth points in the same menu. That is fifty times the Floor 2 price, and no recording has shown what sits behind it.

Decision

When a storey beats an upgrade

Space and rate are the two different things the two menus sell.

Buy the storey when space is the limit: large models crowd a single plot. A Triceratops read $2B with a 0.0286% roll in the September 1, 2026 recording and occupied a very large area, which pushes out cheaper earners on the ground floor.

Buy the upgrade when rate is the limit: a pen that cannot fill its floor is not short of room. Cash Boost, Multi Roll, Luck Boost, and Gems Per Min change what the pets you already own produce.

The tie-breaker is the reset cycle: floors are bought once and stay; the Upgrade board is where every future rebirth point also wants to go. If the next rebirth is close, read the Floors menu again after it.

Honest gaps

What the recordings did not settle

Four open questions, printed as open rather than answered from another zoo game's playbook.

Floor 3 contents: unknown. Reaching 5,000 rebirth points takes a long session and no checked recording got there.

What a storey changes numerically: no recording shows a pen on the second floor paying a different rate for the same pet, so nothing here claims a floor bonus.

Whether higher storeys add slots or space only: the second storey was used as a display area for a large pet, which is the only visible use so far.

Where to confirm: the Floors menu on your own plot is the authority for both the price and what a purchased storey looks like in the current build.

FAQ

Frequently asked questions about floors

Prices, the trade-off against upgrades, and what happens to a floor after a rebirth.

How do you unlock Floor 2 in My Billionaire Zoo?

Spend 100 rebirth points in the Floors menu. Rebirth points come from the rebirth reset, and the same points buy the upgrades on the Upgrade board, so the cost is really what you gave up on the board.

How much does Floor 3 cost?

The Floors menu listed 5,000 rebirth points for Floor 3 in the August 15, September 1, and October 14, 2026 recordings. That is fifty times the Floor 2 price.

What is on Floor 3?

Unknown. No checked recording ever reached 5,000 rebirth points or unlocked Floor 3, so this page prints the price and stops there rather than describing a storey nobody has shown.

Is a floor worth more than upgrades?

They buy different things. A storey adds placeable space, which matters once large models like a Triceratops fill the ground plot. The Upgrade board raises the cash per second that every pet already placed pays. Unlock the storey when space, not rate, is what is blocking you.

Do floors reset when you rebirth?

No recording shows a floor being taken away by a rebirth. The Floors menu kept Floor 1 marked as unlocked across many resets in the same August 15, 2026 session, which is the only evidence this page has for that claim.

How many floors does the zoo have?

The menu showed Floor 1, Floor 2, and Floor 3. Whether a further storey exists above the third was not shown, because the menu was never scrolled past it on screen.
