FAQ

Frequently Asked Questions

When do I unlock Rebirth?
The Answer

You unlock the Rebirth feature when your total base valuation hits roughly 50 to 100 Sextillion.

Important Note

Rebirth tracking is not strictly about how much cash you currently hold in your wallet. It calculates your total progression value, including the money you have already spent upgrading your stats and buying buttons around your base.

When do I unlock Evolution, and what does it do?
The Milestone

Evolution unlocks later in the game, requiring a total cash/base valuation estimate between 50 to 100 Octillion, alongside reaching a specific benchmark of Investors.

The Reward

Activating an Evolution grants your base a massive 42x income speed buff. This means every consecutive evolution allows you to progress through the game roughly 42 times faster than the previous tier.

When do I unlock Remote Buy, and how much does it cost?
The Milestone

Remote Buy becomes available around Evolution 6.

The Cost

It costs a staggering Trigentillion Investors.

Community Consensus

The player base generally considers this specific pricing hurdle to be quite unbalanced. Trigentillion investors is a target reached only minutes before you are ready to Ascend, making the late-game Remote Buy item less impactful than it should be.

How do I solve the Sewer Mazes?
The Puzzles

There are two distinct hidden puzzles inside the Sewers: one rewards you with the UFO Key to secure the permanent 2x Investor multiplier, and the other unlocks access to the Cosmic Cash Vines.

How to Clear

Because the maze patterns require very specific lever sequences, the fastest way to solve them is by pulling up a dedicated visual step-by-step video tutorial on YouTube or joining the Bloxs by Games Discord server to get real-time maps from community members.

Why do some players have a 32% Investor Multiplier?
Free-to-Play (F2P) Limit

A standard free-to-play player can reach a maximum caps-out limit of 2% by finding the hidden sewer UFO key.

Pay-to-Win (P2W) Stacking

High-tier leaderboard players buy the "Double Investors" Gamepass up to 4 times, stacking it significantly. Combined with purchasing the four-stack Speed Gamepass and utilizing Remote Buy, P2W players can end up progressing over 1,000 times faster than F2P players.

When do I unlock the Stairway?
The Threshold

You can build and unlock the Stairway for the first time once you cross into the Tredecillion cash territory.

When do I unlock Ascension, and what are the requirements?
The Milestone

Ascension becomes available during Evolution 6.

The Requirements

To trigger Ascension, you must fully complete construction on the Stairway and purchase every single button in your tycoon, including optional cosmetic decorations. This requires an investment of roughly Duo-Octogentillion cash and an investor count climbing into the Trigentillion range.

What exactly happens when I ascend?

When you Ascend, your world resets but you receive three core rewards, balanced by one steep penalty:

7.77x Global Cash Multiplier

You automatically earn 7.77x more cash for everything sold.

1x Forever Purchase Token

You receive an item token to permanently save a piece of your base.

Cosmetic Halo

A floating halo appears over your Roblox character's head.

The Price Inflation Penalty

Everything in the tycoon will instantly become 3.33x more expensive to purchase.

Math Breakdown

Dividing your 7.77x cash increase by the 3.33x cost increase leaves you with a net 2.33x progression speed buff. Because this mechanic is completely multiplicative, your net buff compounds exponentially (2.33 x 2.33 x 2.33...) every single time you complete an Ascension.

What is a Forever Purchase and how do I get it?
How to Obtain

You can claim a Forever Purchase token by successfully completing an Ascension, or by purchasing it directly for 1,499 Robux.

What it Does

Activating this token allows you to select any single purchase button in your tycoon and make it permanently unlocked. The chosen button will stay active through all future Ascensions, removing the need to ever pay for it again.

What is the best first Forever Purchase?
Top Priority

The most optimal candidate for your first Forever Purchase is the 42x Global Cash Upgrade button.

Alternative Good Targets

The two separate 16x Global Cash buttons found around the base are also top-tier choices.

What to Avoid Early

Do not use your early tokens on the late-game Lemon X Income Source or its Manager. While they boast high raw values, their production speed is incredibly slow; you need to secure multiple Global Speed buttons first before those sources become economically efficient.
