Soul Egg

Soul Eggs (SE) are one of two types of Mystical Egg found in Egg, Inc.. They are primarily earned through Prestige and permanently increase your earnings by 10% each. This bonus can be enhanced through the Soul Food epic research, Eggs of Prophecy, certain Artifacts and Eggfinity Stones.

Soul Eggs appear as cracked stone eggs with a purple icosahedral gem embedded in the center.

Obtaining[]

Soul Eggs are mainly earned by prestiging. You can also get them from:

Completing Challenges andTrophies
the Daily Gift Calendar
Rewards in some Contracts

The number of Soul Eggs earned from a prestige depends on how many Bocks you've earned since your last prestige — your Prestige Earnings. The more Bocks you've earned, the more Soul Eggs you'll gain. Bonuses like Phoenix Feathers and Soul Beacons also multiply your Soul Egg gains.

The rate of Soul Egg gain slows as your Prestige Earnings increase, encouraging frequent prestiging over waiting.

You can find your current Prestige Earnings under 9-Dot Menu → Stats. Enter that number as x in the formula below.

${\textstyle {\begin{aligned}{\text{If current Prestige Earnings are less than 1Nd, then: }}~~~~~~~\\\\{\text{SE Gained}}=~&{\text{(Prestige Bonus Epic Research)}}\times {\text{(Event Boost)}}\times \{\\&\max \left(0,(10^{-6}\times \min(x,10^{12})\right)^{0.15}-(10^{-6})^{0.15})+~\\&\max \left(0,(10^{-6}\times \min(x,10^{21})\right)^{0.16}-(10^{6})^{0.16})+~\\&\max \left(0,(10^{-6}\times \min(x,10^{30})\right)^{0.17}-(10^{15})^{0.17})+~\\&\max \left(0,(10^{-6}\times \min(x,10^{39})\right)^{0.18}-(10^{24})^{0.18})+~\\&\max \left(0,(10^{-6}\times \min(x,10^{48})\right)^{0.19}-(10^{33})^{0.19})+~\\&\max \left(0,(10^{-6}\times \min(x,10^{60})\right)^{0.20}-(10^{42})^{0.20})+~\\&\max(0,(10^{-6}\times {x})^{0.21}-(10^{54})^{0.21})\\&\}\\{\text{If current Prestige Earnings are greater than 1Nd, then: }}\\\\{\text{SE Gained}}=~&{\text{(Prestige Bonus Epic Research)}}\times {\text{(Event Boost)}}\times \{\\&((10^{-6}\times {x})^{0.21}-1.56\times 10^{11})\\&\}\\\end{aligned}}}$

Upgrading[]

There are a several ways to increase the bonus from Soul Eggs above the 10% base.

Soul Food[]

An Epic Research upgrade that increases the bonus per Soul Egg by 1 percentage point per level. At level 14, the bonus becomes 24% (10% base + 14%). The maximum bonus is 150% at level 140.

Soul Stone[]

A type of Eggfinity Stone that increases the bonus given by soul eggs when used in an artifact.

Eggs of Prophecy[]

Eggs of Prophecy are the second type of Mystical Egg found in Egg Inc. They are a powerful way to significantly increase the bonus from Soul Eggs.

Each Egg of Prophecy increases Soul Egg effectiveness by 5–10%, depending on your Prophecy Bonus. This bonus stacks multiplicatively and can be enhanced further with Prophecy Stones and the Book of Basan. Because this bonus is compounding, a small number of Eggs of Prophecy can greatly increase the bonus from Soul Eggs.

Additional Information[]

If you have an increased Soul Egg collection rate, you need to multiply any bock amounts earned while the rate was in effect by the appropriate factor to determine a modified Prestige earnings number to plug into the formula above. For example, if you earned 10 vigintillion Bocks without any Soul Egg collection rate modifier, then 20 vigintillion more bocks while you have a 500x Soul Beacon active, then 36 vigintillion more Bocks while you have both the 500x Soul Beacon and a +400% Phoenix Feather active, then your modified Prestige earnings would be 10 + 20(500) + 36(500)(5) vigintillion = 100.01 unvigintillion Bocks, and so you would plug that number into the above formula.

Trivia[]

An icosahedron is a 3D shape with 20 polygonal faces. The jewel inside the Soul Egg is a regular icosahedron, which means its 20 faces are all equilateral triangles, and this means there are 5 faces visible around each vertex, leading to the 5 most visible faces of the jewel in this picture.
At least one Soul Egg is required before the game asks the player for permission to track a device. However, this message hasn't been shown even though the files include a tracking message in the files.
The purple gem inside the egg is the inspiration for Soul Stones.
