Jump To Steal An Egg Speed to Unlock Biome: 20B Grind Plan

Hitting 20 billion Speed is the gate every Jump To Steal An Egg player runs into when chasing the next biome, because almost every locked area behind the second egg tier demands that exact number before the entrance even renders. This walkthrough maps the speed-to-unlock grind from a fresh pen to a 20B Speed stack, lists which eggs actually move the needle, and shows the order to spend cash so you never waste a rebirth on a pet you will replace twenty minutes later. Use it as a single source of truth while you push toward the next biome.

What "Speed" Actually Means For Biome Unlocks

Speed in Jump To Steal An Egg is a hidden stat that is built up indirectly through the pets you hatch and place inside your pen. Every pet you own adds a flat Speed bonus on top of its cash-per-second income, and that Speed number is what the game reads when it decides whether a biome gate is open or sealed. A locked biome stays sealed even if you physically stand on its entrance until your combined Speed crosses the threshold posted above the door, which is why two players at the same level can see completely different zones rendered on the map.

The community has confirmed through testing that the classic early-game targets — T-Rex, Unicorn, Sphinx and Cobra eggs — form the foundation of any Speed stack, but they only carry you to roughly the first biome wall. Past that point, the egg pool shifts toward high-Speed hatchables and the cost-per-roll climbs into the billions, which is exactly why planning a grind route matters more than rolling blindly.

The cash-per-second line is the one most players underestimate, because it is also the engine that funds the next egg roll. A pet that pays $100M per second quietly funds a second pet of the same tier inside a single long AFK session, which is why a mid-game pet that looks "weak" in raw Speed is actually a cash engine that pays for the pet that will push you past the 20B wall.

The 20B Biome Gate Explained

The 20B Speed biome is not a hidden zone — it is a fully rendered area on the map, but its entrance stays visually sealed with a red barrier and a number floating above it. The barrier only drops once your total pet Speed crosses 20,000,000,000 (20B), and the number is cumulative, not per-pet. That means you do not need a single pet worth 20B Speed; you need a roster that, when added together, clears 20B.

The Angel and Demon Eggs are the two eggs whose hatch pool is designed to push players over this exact line, because their top outcomes (ArchAngel and World Burner) each add multi-billion Speed on their own. Community reports put ArchAngel in the 5B to 8B Speed range and World Burner in the 8B to 12B range, which means a roster of three or four of these pets clears the wall on its own — but the cost to roll them is brutal, and that is the grind this guide focuses on solving.

Mapping The Locked Biome Entrance

The locked biome entrance is one of the most reliable signals in Jump To Steal An Egg, because the gate number is the exact Speed total you need, not a vague suggestion. Walking up to any sealed biome entrance and reading the floating number tells you whether the next tier egg is worth chasing or whether you should detour back into cash farming first. The biome unlock speed reference breaks down every entrance on the current map with the exact Speed totals each one demands, which is a useful cross-check while you plan a push.

There are four biome categories in the current build, and each one asks for a different Speed tier. Forest and Desert are the early walls at around 5K to 50K Speed, Snow sits in the mid-game at roughly 500K to 5M, and Volcano plus the new biome additions sit at the 1B to 20B ceiling. Knowing which tier you are stuck on tells you which egg pool to target, which keeps the cash-per-roll ratio in your favor.

The roll cost column is the one that traps most players, because each tier costs roughly ten times more per roll than the one before it. A Volcano-tier egg roll can cost $500M, which is nothing if your roster is printing $100M a second, but it becomes a serious grind if you are still rolling Forest-tier eggs on a $2,000-per-second pet.

The 20B Speed Grind Plan

The grind plan below assumes a fresh pen, no codes redeemed, and a target of clearing the 20B biome gate as cheaply as possible. It is split into four phases, and each phase has a clear cash goal that you should not move past until it is met, because skipping phases is the single most common reason players run out of cash mid-push and have to rebirth into a worse position.

Phase 1: Forest Cash Engine (0 to ~50K Speed)

Phase 1 is about building a cash engine, not a Speed stack. The goal is to hatch and place T-Rex and Unicorn eggs until you have at least three pets in your pen that together earn over $5,000 per second, because that is the income level that funds Desert-tier rolls without rebirths. Skip Cobra for now; it costs more per roll and the Speed payoff is not worth it at this stage.

Use the cash flow to roll Forest eggs aggressively until one of the rare outcomes drops. T-Rex and Unicorn pets in the 4,000 to 8,000 Speed range are the targets, and the moment one drops, place it immediately and let the cash-per-second compound while you keep rolling. Most players hit the Forest biome wall inside 20 to 40 minutes on a clean run if they resist the urge to spend on trails or cosmetic upgrades during this phase.

Phase 2: Desert Cash Pivot (~50K to ~500K Speed)

Once Forest is open, the goal is to pivot your cash engine into Desert-tier eggs as fast as possible, because the Speed per roll is roughly 5x to 10x higher and your existing income is high enough to absorb the cost. Sphinx is the priority target here, because its top outcome (Royal Sphinx) earns $280,000 per second and grants +18,000 Speed, which is a double win for both income and the upcoming Snow wall.

The Cobra egg is worth rolling only if you already have at least $50M in cash reserves, because its rare outcomes are the only way to bridge the gap from Desert income to Snow-tier rolls without rebirths. A common mistake is rolling Cobra too early and burning the cash reserves you need for Sphinx, which leaves you stuck at the Desert biome wall with no momentum.

Phase 3: Snow To Volcano Bridge (~500K to ~5M Speed)

Phase 3 is the longest stretch of the grind, because the Snow and Volcano biomes are where pet Speed values jump into the tens of thousands and roll costs climb into the millions. The Ice Dragon and Lava Dragon are the two outcomes that make this phase worth pushing through, because Eternal-rarity pets at this tier earn $65M to $100M per second and grant +32K to +60K Speed each, which is the income engine that funds the eventual 20B push.

This is also the phase where codes start to matter, because a single redeemed code from the active codes list can drop a free egg or a cash boost that saves you a full hour of grinding. Redeem codes at the start of every session, not the end, because the cash boost compounds for the rest of that session and stacks with your pet income.

Phase 4: The 20B Push (~5M to 20B Speed)

Phase 4 is the actual 20B Speed grind, and it is where most players fail because they try to brute-force the Angel and Demon egg pool without enough income. The minimum income threshold for a clean 20B push is $500M per second, which means you need at least one Eternal-tier pet (Ice Dragon, Lava Dragon, Phoenix, or similar) producing income before you start spending serious cash on Angel and Demon rolls.

The table above assumes you are rolling on luck as much as on cash, because both Angel and Demon Eggs have low hatch rates on their top outcomes. A World Burner from a Demon Egg is roughly 1% to 3%, and an ArchAngel is similar. The grind plan is to keep rolling, not to chase a specific pet, because the cumulative Speed of any high-rarity Angel or Demon outcome gets you closer to the 20B wall even if it is not the absolute top pet.

Hidden Biome Triggers And Shortcuts

Most players assume the only path to a new biome is the Speed gate, but Jump To Steal An Egg also has hidden triggers that can open or hint at a biome before the Speed wall is technically cleared. The Sunday mega update cycle is the most reliable of these triggers, because the developer publishes a new biome reveal every Sunday alongside new animals and an admin abuse event, and the entrance for the revealed biome often has a reduced Speed gate during the first 24 hours of the event.

A second hidden trigger is the Together for Animals group join reward, which is confirmed to grant a free in-game bonus that includes a small Speed buff. This is a one-time reward per account, but it is worth claiming before you start the 20B push because the Speed bonus stacks on top of your pet Speed and can shave a few hundred million off the final grind.

A third shortcut is the AFK income loop, because every pet in your pen earns cash even when you are offline. The official Jump To Steal An Egg page on Roblox confirms offline earnings as a core feature, which means a long AFK session overnight is functionally the same as a focused grind session in terms of cash generated. Stack your AFK time right before a planned push, not after, because the cash lands in your account right when you log back in and is immediately available for the next roll.

Common Mistakes That Reset The 20B Progress

The fastest way to fail the 20B push is to rebirth at the wrong moment, because rebirth resets your pet roster and your Speed stack while keeping only a small permanent bonus. A rebirth is worth it only when the permanent bonus multiplies your next push by more than the Speed you would lose, which means a rebirth at 1M Speed is almost always a mistake and a rebirth at 5M Speed with a 5x permanent multiplier is usually a win.

A second mistake is rolling eggs outside your current cash tier. A player with $5M in the bank should never roll a $500M Volcano egg, because the variance on a single roll is high enough that one bad roll wipes the entire reserve. Always roll eggs that cost less than 10% of your current cash, because that keeps the variance survivable and lets the cash engine recover between rolls.

A third mistake is ignoring the Speed-to-cash ratio when placing new pets. A pet that grants +60,000 Speed but only $85M per second is not always better than a pet that grants +32,000 Speed and $100M per second, because the cash engine is what funds the next roll. Place high-Speed pets only after you have a stable cash engine, and prioritize cash-per-second pets during the income-building phases.

The "codes unclaimed" row is the one that compounds the worst, because every session that starts without redeeming codes is a session that runs at 70% to 90% of optimal income. Build the habit of redeeming codes the moment you log in, before you do anything else, because the boost is time-gated and any time spent on other actions is time the boost is not active.

Biome-Locked Pet Income And Why It Matters

Every biome in Jump To Steal An Egg has a small handful of pets that drop only inside that biome, and those pets are the long-term reason to clear the 20B gate even if the gate itself does not unlock anything you need. A pet like the Forest Chicken drops commonly and earns $1 per second plus +420 Speed, while a Snow-tier Ice Dragon drops rarely and earns $65M per second plus +32K Speed. The income gap between a common Forest pet and a rare Snow pet is roughly 65,000x, which means a single rare pet replaces a roster of tens of thousands of common pets in pure cash terms.

This is the core reason the 20B grind is worth it, because the Angel and Demon Egg pets (ArchAngel, World Burner, and their supporting roster) earn at a tier that makes the rest of the game feel free. Once your income is over $500M per second, every future egg roll is funded by passive AFK time and you never have to grind for cash again — the only grind left is rolling for the next Speed pet to push the next biome gate.

The jump-power and trail systems also scale off your pet income indirectly, because higher-income runs let you reinvest into jump upgrades faster. The jump power and trail system guide covers the exact ratios, but the short version is that every dollar spent on jump upgrades saves you time on the next Speed pet roll, which compounds the 20B push even further.

Endgame Strategy After The 20B Wall

Clearing the 20B wall is not the end of the game, because the next biome that lands on a Sunday update typically opens at a Speed gate of 50B or higher, and the pet roster needed to push that wall is its own grind. The strategy that scales best is to keep at least 30% of your cash reserve unspent at all times, so a new biome announcement does not force you into a roll you cannot afford.

Join the Together for Animals community on Roblox for the earliest heads-up on new biome reveals, because the group posts new codes and biome teases hours before the in-game update lands. That window is when you want to time your next rebirth or your next big cash reserve, not after the update has already dropped and the rest of the server is competing for the same eggs.

A second endgame tactic is to keep two pen loadouts, one Speed-focused and one cash-focused, and swap between them based on what you are grinding. Speed loadouts for clearing the next biome gate, cash loadouts for funding the next egg pool. The swap is free and instant, which means the cost of running a dual setup is zero and the benefit is a smoother grind loop.

Frequently Asked Questions

What is the exact Speed number for the 20B biome in Jump To Steal An Egg?

The 20B biome gate requires 20,000,000,000 total pet Speed, which is a cumulative stat across every pet in your pen, not a single-pet requirement. Hitting it is the unlock condition for the highest-tier biome currently in the build.

Which egg should I roll first for the 20B push?

Roll the Demon Egg first once you have a stable $500M-per-second cash engine, because the World Burner outcome is one of the single highest-Speed pets in the game and tends to drop at a slightly higher rate than the ArchAngel from the Angel Egg during the early phase of a push.

Can I unlock a new biome without the 20B Speed total?

No for the standard 20B biome, yes for the temporary Sunday update biomes, which often open at a reduced Speed gate during the first 24 hours of an event. The reduced gate is enough for most players with a mid-game roster to enter, but the permanent gate resets to 20B after the event window closes.

What happens if I rebirth at 5B Speed during the push?

You lose every pet in your pen and your Speed stack drops to whatever your permanent multiplier produces from scratch, which is usually in the low millions. A rebirth at 5B Speed is only worth it if the permanent bonus multiplies your next push by more than 10x, which is rare before you have several Eternal-tier pets contributing to the total.

How long does the 20B grind take on average?

A clean run with no rebirths and a stable cash engine typically takes 6 to 12 hours of active play plus overnight AFK time, depending on hatch luck. Players with strong Eternal-tier pets already in their pen can clear the gate in 2 to 4 hours because their income is high enough to roll the Angel and Demon Eggs aggressively from the start.
