Boosts are temporary bonuses that a player can benefit from in Egg, Inc. Each of them can be purchased in the boost shop for Golden Eggs. The exception to this is the 2x ad boost, which is activated by watching a video advertisement. By default, the farmer can activate up to 2 boosts simultaneously. This is upgraded to 5 with the pro permit.
Boosts cannot be used on enlightenment egg farms.
However, in Contracts, boosts can only be used when one spends a boost token, which is given periodically depending on the contract.
The fastest way to prestige at the end of the game is to use 2x Jimbo's Best Bird Feed 10min, 1x Legendary Soul Beacon, 1x Legendary Tachyon Prism, and 1x Legendary Boost Beacon, use the running chicken bonus until habs are maxed out, and prestige.
