Check egg odds, find the best egg for your budget, and simulate hatches with confidence levels. The only GAG egg tool with an exclusive Hatch Simulator that calculates exactly how many eggs you need for your target pet.
These are the most common questions GAG players search for. All numbers use the formula P(at least one in n eggs) = 1 − (1 − p)n, with drop rates sourced from the official Grow a Garden Fandom wiki (verified June 2026). Use the Pet Calculator to check current trade values.
| Pet | Source Egg | Drop Rate | 50% Conf. | 75% Conf. | 90% Conf. | Cost at 90% |
|---|---|---|---|---|---|---|
| Kitsune | Zen Egg | 0.08% (1/1,250) | 866 | 1,733 | 2,877 | Event only |
| Raccoon | Night Egg | 0.1% (1/1,000) | 693 | 1,386 | 2,302 | Event only |
| Raccoon | Premium Night Egg | 1% (1/100) | 69 | 138 | 229 | Robux only |
| T-Rex | Dinosaur Egg | 1% | 69 | 138 | 229 | ~22.9M Sheckles |
| Dragonfly | Bug Egg | 1% | 69 | 138 | 229 | ~11.45B Sheckles |
| Fennec Fox | Oasis Egg | 0.5% | 139 | 277 | 460 | Robux only |
| Queen Bee | Bee Egg | 1% | 69 | 138 | 229 | Honey / event |
| Disco Bee | Anti Bee Egg | 0.25% | 277 | 554 | 920 | Craftable / event |
| Elephant | Safari Egg | 100% | 1 | 1 | 1 | 150,000 Sheckles |
| Polar Bear | Legendary Egg | 2.13% | 32 | 64 | 106 | ~318M Sheckles |
| Mimic Octopus | Paradise Egg | 1% | 69 | 138 | 229 | ~11.45B Sheckles |
| Spinosaurus | Primal Egg | 0.5% | 139 | 277 | 460 | Craftable / event |
Use the Hatch Simulator tab above to run these numbers for any pet at any confidence level. The formula is shown transparently.
The Grow a Garden Egg Calculator is a free browser tool for Roblox GAG players who want to spend their Sheckles smarter. It does three things no other tool combines in one place: shows the full pet drop table for every egg, calculates the best ROI egg for your budget, and runs an exclusive Hatch Simulator with confidence levels so you know exactly how many eggs you realistically need for any specific pet.
Most players open eggs based on gut feeling or Discord advice. The problem is that gut feeling ignores a core truth about random drops: the number most players call the average only gives you a 63% chance of success. That means 37 out of every 100 players who open the average number of eggs still leave empty-handed. This calculator shows you the full probability picture before you commit a single Sheckle.
The tool covers 20+ egg types across permanent shop, specialty, and recurring event categories, 170+ pets, 7 rarity tiers from Common through Prismatic, all Sheckle and Robux prices, and a Best ROI tab that ranks eggs by expected value for any budget you enter.
The tool has three tabs. Each one answers a different question.
Tab 1: Egg Odds — Select any egg from the card grid. The calculator loads the complete verified pet drop table for that egg showing every possible pet, its individual drop rate percentage, rarity tier, and Sheckle value. Results are sorted rarest first so high-value targets always appear at the top.
Tab 2: Best ROI — Enter your Sheckle budget and choose a sort mode: Expected Value, Best Pet Chance, or Rarest Pet. The calculator ranks all eggs instantly. This answers the question most players ask before spending: which egg should I open right now for my budget?
Tab 3: Hatch Simulator — Select a target pet from the dropdown. Set your confidence level using the slider from 50% to 99%. The simulator shows three scenarios: Lucky Case (first egg), Average Case (63% mark), and Worst Case (99% confidence). A probability bar chart shows your cumulative odds at multiple egg counts. Enter a Sheckle budget and the tool shows you exactly what confidence level that budget buys you.
Each Egg Roll Is Fully Independent. When you open an egg in Grow a Garden, the game runs a single independent random roll against that egg's drop table. The outcome is completely unaffected by every egg you have opened before. Opening 2,000 Zen Eggs without getting a Kitsune does not increase the probability of egg 2,001 producing one. Every roll resets to exactly 0.08%. This is the independence property of probability and it is the single most important thing to understand about the entire egg system. Players who believe they are "due" for a rare pet after a long dry streak are experiencing what statisticians call the gambler's fallacy — the game has no memory of your previous rolls.
Why the Average Number Is Misleading. The average number of eggs to get a specific pet is 1 divided by the drop rate. For Kitsune at 0.08%, the average is 1,250 eggs. Here is what most players do not realize: opening 1,250 Zen Eggs only gives you a 63.2% chance of getting a Kitsune. More than one in three players who opens the average number still walks away empty-handed.
This is the exact formula the Hatch Simulator uses. It is displayed transparently so you can verify the math yourself. No other GAG calculator exposes this formula. The bar chart in the Hatch Simulator shows cumulative probability at 10, 20, 50, 100, 200, and 500 egg counts — red bars mean below 50%, yellow means 50-90%, green means above 90%. For a rare pet like Kitsune, most bars stay red even at 500 eggs, making the true difficulty immediately visible.

These eggs can no longer be hatched fresh. They exist in the economy only as traded items from players who hatched them during their original events. The Enchanted Egg was retired September 13, 2025. Seasonal eggs (Spooky, Winter, Springtide) may return during their respective seasons. For the complete archive of all eggs including hatch times and shop spawn rates, see the complete Grow a Garden Eggs List guide.
This is the most important section on this page for anyone planning to hunt a rare pet, and the reason the Hatch Simulator is more useful than any simple drop rate table. When players see a drop rate, most read it as the number of eggs they need. The reality is more complicated. Here is the full breakdown for a 1% drop rate pet versus a 0.08% drop rate pet:
| Confidence Target | Eggs at 1% rate | Eggs at 0.08% rate (Kitsune) | What It Means |
|---|---|---|---|
| 50% | 69 eggs | 866 eggs | Coin-flip. Half of all players get it, half do not. |
| 75% | 138 eggs | 1,733 eggs | Three in four players succeed within this count. |
| 90% | 229 eggs | 2,877 eggs | Nine in ten players succeed. Realistic planning target. |
| 99% | 458 eggs | 5,754 eggs | Near-certain but extremely expensive for rare eggs. |
| 99.9% | 687 eggs | 8,630 eggs | One in a thousand players still misses at this count. |
The takeaway: plan for the 90% number, not the average. At 90% confidence you have nine in ten odds of success. Budgeting for the average number means a one in three chance of running out before you succeed. For Kitsune specifically, the 90% target is 2,877 Zen Eggs — a massive Chi or Robux investment. This is why trading for a Kitsune is almost always more efficient than hatching for one. The Hatch Simulator lets you set the confidence slider to any level from 50% to 99% and shows the exact egg count and total cost. Cross-check with the Pet Calculator for the current trade value of your target pet before committing.
Worked Example: Kitsune. Using a hypothetical 200,000,000 Sheckle trade value for illustration: Zen Eggs cost 30 Chi or 149 Robux each (not Sheckles). The total cost to reach 90% confidence (2,877 eggs) depends entirely on your Chi farming rate or Robux budget. To reach 50% confidence you need 866 eggs — even at the cheapest Robux price, that is a significant investment. Trading at 200M Sheckles is almost always more efficient than hatching for Kitsune, regardless of how you acquire Zen Eggs. Trading wins at virtually every confidence level for Kitsune.
When Hatching Actually Beats Trading: The pet has a high drop rate (above 5%), making expected cost low relative to trade value. The egg contains multiple valuable pets so failed attempts for your target still produce usable pets. No trade partners are available and you need the pet immediately. The egg is event-only and the event is currently active — post-event trade prices will be higher. Use the Trade Calculator to verify any pet's current trade value before making this comparison. Trade values shift weekly with patches.
Why Event Egg Pets Have Inflated Trade Value After Events Close. When an event ends, new supply of that egg's pets stops permanently. The total supply in the economy is frozen at whatever players hatched during the event window. If demand stays constant while supply is capped, trade value rises over time. This is why pets like Raccoon, Swan, and Queen Bee command premium prices long after their events. The practical implication: opening event eggs during the active window is the only route to acquisition at face value. After the event closes, your only option is paying the inflated trade price. If you see an event egg with a pet you want and can afford it, opening during the event is almost always the correct long-term decision.
Anti Bee Egg: The Only Craftable Egg. The Anti Bee Egg is unique because it can be crafted rather than purchased directly. Combine one Bee Egg with 25 Honey at the crafting station. This is worth doing if you already have surplus Bee Eggs and a Honey supply because it unlocks a completely different pet pool (Wasp, Tarantula Hawk, Moth, Butterfly, Disco Bee) without buying an additional egg.
Premium Variants: Same Pool, 30-Second Hatch. Most event eggs have a Premium counterpart that costs Robux and hatches in 30 seconds instead of the standard 4+ hours. The pet pool is usually the same, but some premium variants have slightly adjusted drop rates. Notable exception: Premium Night Egg has Raccoon at 1% versus the standard Night Egg's 0.1% — ten times higher odds for the rarest pet in that pool.
| Your Goal | Best Egg | Why | Expected Value / Note |
|---|---|---|---|
| Maximize Sheckle ROI | Zen Egg | Kitsune (0.08%) and Tanchozuru are highest value pets in pool | 30 Chi / 149R per egg |
| Budget farming | Bug Egg | Dragonfly turns fruit gold. Praying Mantis gives 1.5x mutation chance | ~35K per 30M egg |
| Mutation-trigger pet | Legendary Egg | Polar Bear (2.13%) triggers Chilled and Frozen mutations | ~15K per 3M egg |
| AFK garden setup | Paradise Egg | Capybara (21%) exclusive here. Mimic Octopus (1%) is top prize | ~60K per 50M egg |
| Chase Prismatic | Zen Egg | Kitsune is only Prismatic in Zen Egg. Gem Egg also has Prismatic | Most expensive hunt |
| Guaranteed Divine | Safari Egg | 100% Divine (Elephant) every single open. No RNG. | = 150,000 Sheckles |
| Steal/duplicate crops | Night Egg | Raccoon (0.1%) duplicates crops from other gardens every 15 min | Event only. Premium = 1% |
| Complete beginner | Rare Egg | Affordable at 600K. Rooster gives 20% hatch speed boost | ~3,500 per egg |
| Hatch speed pets | Uncommon Egg | Chicken (10% speed) at 150K. Stack with Rooster later | 500 per egg |
| Event-exclusive | Current event egg | Check event shop during active event window | Price inflates after event |
Expected values are probability-weighted averages. Your actual return from any single egg will differ. For which pets are worth keeping after hatching, see the Pet Tier List.
A question no other guide answers: what is the cheapest egg path to your first pet at each rarity level?
| Target Rarity | Cheapest Egg | Cost per Egg | Avg Eggs to First Pet | Notes |
|---|---|---|---|---|
| Common | Common Egg | 50,000 | 1 (guaranteed) | All three pets are Common |
| Uncommon | Uncommon Egg | 150,000 | 1 (guaranteed) | All four pets are Uncommon |
| Rare | Rare Egg | 600,000 | 1 (guaranteed) | All five pets are Rare or above |
| Legendary | Legendary Egg | 3,000,000 | ~1.2 eggs | Cow and Silver Monkey at 42.55% each — fastest Legendary access at 3M per egg |
| Mythical | Mythical Egg | 8,000,000 | ~2.8 eggs | Grey Mouse 35.71% is fastest Mythical access |
| Divine | Safari Egg | 150,000 | 1 (100%) | Elephant guaranteed. Best value Divine access in the game. |
| Prismatic | Gem Egg | 250,000,000 | Very high RNG | Ruby Squid is Prismatic. Zen Egg has Kitsune at 0.08%. |
The Safari Egg remains the most overlooked value egg in the game. At 150,000 Sheckles with a 100% Divine drop, it costs less than a single Rare Egg and guarantees a Divine pet every time. The Bug Egg at 50,000,000 Sheckles with a 1% Dragonfly rate requires an average of 100 opens (5,000,000,000 total Sheckles) for one expected Divine. Safari Egg wins on expected cost for Divine access by an enormous margin.
| Stage | Pet Combo | Speed Effect | How to Get |
|---|---|---|---|
| Early game | Chicken only | 10% global speed boost | Uncommon Egg — 150,000 Sheckles |
| Mid game | Chicken + Rooster | 30% combined boost (additive stack) | Uncommon + Rare Egg |
| Late game | Rooster + Kiwi | 20% boost + 25 seconds removed per minute | Rare Egg + Kiwi (event pets) |
| Endgame | Blood Kiwi + Rooster | 20% boost + 45 sec/min removed + 20% bonus | Lunar Glow event only |
| Max stack | Multiple Blood Kiwis | Each stacks independently on longest egg | 5 Blood Kiwis = 100% speed + 225 sec/min |
You can expand your egg slots beyond the starting 3. Trading age-353+ pets to Raphael unlocks more slots. The Garden Ascension Shop sells up to 5 additional slots for 40 Garden Coins each. Maximum is 13 simultaneous slots. Running all 13 with Blood Kiwi booster pets is the endgame meta for hatch throughput. Use the Crop Planner alongside this calculator to maximize Sheckle output per session while your eggs are hatching offline.
Several eggs can be bought with either Sheckles or Robux. Whether Robux is worth spending depends on your Sheckle farming rate and the egg's Sheckle equivalent cost.
| Egg | Robux | Sheckles | Farm Time (at 1M/hr) | Robux Worth It If... |
|---|---|---|---|---|
| Common Egg | 19 R$ | 50,000 | 3 min | Never. Farm time is trivial. |
| Uncommon Egg | 39 R$ | 150,000 | 9 min | Never unless you need it immediately. |
| Rare Egg | 89 R$ | 600,000 | 36 min | Shop is empty and you need it now. |
| Legendary Egg | 129 R$ | 3,000,000 | 3 hours | Multiple target pets and time is limited. |
| Mythical Egg | 119 R$ | 8,000,000 | 8 hours | Often yes. 8 hours of farming is high opportunity cost. |
| Bug Egg | 149 R$ | 50,000,000 | 50 hours | Almost always yes. 50 hours is a very high bar. |
| Paradise Egg | 139 R$ | 50,000,000 | 50 hours | Almost always yes for same reason as Bug Egg. |
| Prem. Night Egg | 199 R$ | N/A | Not farmable | Only available route. No Sheckle alternative. |
| Oasis Egg | 149 R$ | N/A | Not farmable | Robux only. No free alternative. |
The Robux value proposition improves sharply as egg Sheckle price increases. The Mythical Egg at 119 Robux versus 8,000,000 Sheckles is the practical breakpoint where Robux becomes genuinely competitive for most players. Before spending Robux on any egg, use the Profit Calculator to estimate your current Sheckle income rate.
Common Egg After Your First Week. The Common Egg teaches the hatching loop and costs very little. Past early game it offers no path to any meaningful pet. The entire pool is three Common pets at equal 33.3% odds. Once you have 150,000 Sheckles saved, the Uncommon Egg is strictly better in every respect.
Uncommon Egg (Once You Have Chicken). The Uncommon Egg is worth opening specifically for the Chicken, which gives 10% hatch speed reduction. Once you have one, there is no compelling reason to keep opening Uncommon Eggs because the pool tops out at Uncommon rarity with no Legendary or above.
Zen Egg for Sheckle Farming. The Zen Egg has the best absolute expected value per egg but since it costs 30 Chi or 149 Robux (not Sheckles), it cannot be compared directly on a Sheckle-per-egg basis. If your goal is to maximize Sheckle return relative to investment, the Bug Egg or Rare Egg offer better ratios in pure Sheckle terms. The Zen Egg is worth it specifically when you are hunting Kitsune or Tanchozuru, not for general farming economy.
The pet you hatch from an egg directly determines your mutation potential for crops. This ecosystem connection is covered by no other GAG egg guide.
| Pet | Source Egg | Mutation Effect | Practical Impact |
|---|---|---|---|
| Polar Bear | Legendary Egg | Chilled / Frozen on nearby crops every 90s | Triggers cold mutations which stack with environmental weather multipliers |
| Dragonfly | Bug Egg | Turns a random fruit Golden every 5 min | Passive Gold mutation (20x) applied automatically |
| Praying Mantis | Bug Egg | 1.5x mutation chance nearby every 78s | Increases probability of all mutation triggers in range |
| Pig | Rare Egg | 2x variant chance aura every 118s | Doubles chance of Gold and Rainbow variants on nearby crops |
| Giant Ant | Bug Egg | 10% crop duplication on harvest | Effectively increases harvest yield by 10% |
| Red Giant Ant | Mythical Egg | 5% harvest duplication + 5% bonus for fruits | Best passive duplication pet in permanent egg pool |
| Kitsune | Zen Egg | Chakra mutation + 1% Foxfire Chakra on steal | Unique mutation type only available through Kitsune ability |
For the complete breakdown of how pet mutations interact with crop value multipliers, see the All Mutations in Grow a Garden guide. Use the Mutation Calculator to calculate exactly how much a Polar Bear or Dragonfly improves your expected Sheckle output per harvest. For weather events that amplify mutation-trigger pets, check the Weather Tracker to time your triggers with active weather multipliers like Thunderstorm (Shocked) and Blood Moon.
