Data Sources & Methodology
Each published fact is tied to an original source or explicitly marked unknown. A source-review date is not the same as an in-game test. We bind everything to Roblox universe 10563114921 (the original Steal An Egg) — never to similarly-named copycat games.
Confidence model
How a value becomes 'verified'.
VERIFIED
Official Roblox data, or two+ independent sources agreeing on the specific field.
HIGH_CONFIDENCE
Strong source, partially cross-checked (most pet incomes).
COMMUNITY_REPORTED
Single community source, consistent with mechanics (e.g. mutation odds existence).
UNKNOWN
Not published anywhere reliable. We show “unknown” instead of estimating.
We only use the phrase “verified in-game” when a page has actual first-hand test evidence. A date labelled “source review” means the listed external evidence was reviewed on that date.

The feed names Demons as a live spawn location and shows 'Eternal Skeleton Horse Egg' plus 'Secret Gargoyle Egg' spawning there. It also shows older Cerberus, Tralaledon, Cosmic Skeleton Boss, Ice Dragon and Mutant Shark egg notifications, so those are not attributed to Update #4. The feed says the Riftborn banner is not active, confirming the Rift system still exists. |

| TechWiser: Steal An Egg Biomes and Speed Requirements | MEDIA | medium | 2026-08-30 | Updated Aug 30: confirms 11 biomes incl. Titan Temple at 7B (Gorilla King, recommended 7.5B). Its older-biome guardian names (Moby, Hellhound, Dragon King) match the stale community table — IGN's newer guardian list preferred where they conflict; it names Kitsune as Cherry Blossom guardian vs IGN's Oni Tiger (conflict logged). |

| AllThings.how: Steal An Egg Rift Update: Full Guide to the Abyss Overlord Boss Fight | MEDIA | medium | 2026-09-06 | Rift Update mechanics: Rift opens every 30 minutes; boss loop = destroy power crystals, survive attack barrage, strike the dormant hand, repeat (reported ~27,300 HP); full clear observed awarding ~1,200 Boss Tokens plus an on-screen 'Secret Rift Egg' line; Boss Shop prices match our screenshots; Mutation Consumable reported as the Fractured mutation (+10% money) applied to a growing egg; mastery rewards 3/5/10/15/20/30 (their 30-kill 'Fractured mutation egg' wording conflicts with our screenshot's 'Random Mutated Egg'); Rift egg pool pet name lists for Riftborn/Riftbeasts/Shattered Rift. |
| TechWiser: Steal an Egg Rift Event Guide | MEDIA | medium | 2026-09-06 | Reports the Rift opens every 30 minutes; lists the Riftborn pool as Rift Eye/Voidmaw/Ventinal/Wendigo/World Eater and the Riftbeasts pool as Void Angler/Riftwing/Dreadclaw/Mawbreaker/Void Serpent (corroborating AllThings.how); recommends the 'Fractured Mutation crystal' for an additional 10% money gain. |
| Pro Game Guides: Complete Steal An Egg Rift Event Guide | MEDIA | medium | 2026-09-06 | Describes the lobby Rift Machine as trading three requested pets for a Rift egg and reports defeating the Overlord earning roughly 1,200-1,500 Boss Tokens; lists World Eater as the Riftborn 0.5% slot at 500M/s (Eternal rarity), matching our screenshot's numbers. Interprets the 45/35/20 figures as craft chances, which conflicts with our screenshots labeling them 'Rotation Chances' — the current in-game UI wording wins. |
| Eldorado.gg: Steal An Egg Eggs List — every biome egg with images | MEDIA | medium | 2026-09-06 | 88 biome egg renders used as community-reference artwork for the individual egg pages; names/rarities cross-checked against IGN's pet index (Eternal Gorilla King, Divine Nightflame consistent with IGN's unnamed Divine slot). |
| stealanegg-wiki.com: Steal An Egg Wiki — public client-config mirror (pet GAME CONFIGURATION blocks) | WIKI | medium | 2026-09-06 | Independent wiki that mirrors the game's client configuration (per-pet base income and base model weight). Recorded as client-config-mirror provenance: not official, not developer-confirmed, not the Roblox API. Used only to fill missing values; local values that differ are kept and reported as conflicts. |
| stealanegg.fandom.com: Steal An Egg Wiki (Fandom) — Mutations & Rift Event pages | WIKI | medium | 2026-09-07 | Community wiki. Its Mutations table lists the Rift Update's Fractured mutation at x2.75 income and notes mutations 'can be applied to an egg with a Mutation Consumable for a 10% chance'; its Updates page says the Boss Shop includes 'a chance to apply the new Fractured Mutation to your placed eggs'. Its multiplier scale differs from other community listings (e.g. Golden x2.5 vs Eldorado's x2), so the Fractured x2.75 figure is treated as one community reading, not confirmed. |

Exact inputs, recipes, odds and outputs are not independently verified by the game UI. |
| AllThings.how: AllThings.how — Steal An Egg Trails: Every Speed Multiplier and Price | MEDIA | medium | 2026-09-17 | Independent Trail Shop table reporting ten tiers from Gray to Divine, multipliers from ×1.5 to ×14, and dated cash/Robux snapshots. Prices are version-sensitive and conflict with later public references; used for the multiplier ladder and shop-flow reference only. |
| BuyGAG2 Wiki: BuyGAG2 — Trail Shop: All Trail Prices & Speed Bonuses | COMPETITOR_WIKI | medium | 2026-09-17 | Community Trail Shop reference updated September 11, 2026. It corroborates the ten named tiers and ×1.5–×14 multiplier ladder; its approximate Robux and Divine cash snapshots differ from AllThings.how, so no price is treated as canonical. |
| AllThings.how: AllThings.how — Sammy Is Coming update and Dr. Scramble Event | MEDIA | medium | 2026-09-22 | Independent launch coverage connecting Sammy, Ben and Dr. Scramble and listing the Experiment Shop, two eggs, consumable and Nibbles mission.

| AllThings.how: AllThings.how — Dr. Scramble Samples, Shop and Scrambled guide | MEDIA | medium | 2026-09-22 | Independent guide with the cross-reported Shop costs, three drone labels and 5 HP observation. Exact payout amounts and Scrambled success/multiplier values are not promoted as official. |

The chance and multiplier are kept as conflicting community observations because no first-party tooltip or controlled in-game capture was available. |
| Bloxron: Bloxron — Steal An Egg stealing guide | COMMUNITY_REPORT | medium | 2026-09-22 | Reports a conflicting 1% Scrambled application chance while agreeing on the Shop item family. This record is retained for conflict tracking and is not used as a calculator constant. |
| Pocket Tactics: Pocket Tactics — Steal an Egg codes status | MEDIA | medium | 2026-09-22 | Current independent check says there are no active codes and no redemption system. It is not a developer announcement, so the site uses the safer wording 'No verified active codes.' |
| stealanegg.pro: excluded from public citations | COMPETITOR_WIKI | low | 2026-08-21 | Biome table corroborated by Sportskeeda. WARNING: its pet examples (Cat, Eagle, Shadow Wolf, Golden Hydra) do not exist in any cross-validated list — pet data from this source is excluded. |
Conflict handling
What we exclude and why.
When sources disagree, the conflict is logged in our research docs and the value is labeled with its weakest link. Example: one competitor wiki lists pets (Cat, Shadow Wolf, Golden Hydra) that appear in no cross-validated index — those are excluded entirely. Another competitor's biome table matched Sportskeeda, so biome thresholds ship as cross-checked. Copycat game data is never mixed in.
