The minimum Purse for a lottery’s must be its Quantity times the Price. This (Q \* P) is called the Sponsor Take, and it is automatically transferred to the Sponsor at the lottery’s conclusion. Most lotteries will have a Purse higher than the Take. The difference is called the *Residual* of the lottery. The Residual is important because it can be distributed in a number of wars between the Sponsor, Participants and platform itself. We discuss how the residual is used in greater detail in [Platform Economics](/docs/platform-information/platform-economics.md). --- # Agent Instructions This documentation is published with GitBook.
