Draws run by a charity, for its own work.
The charity behind these draws runs them to raise funds for its own work. Every draw has a fixed closing date and a published result.
Why run a draw at all?
The work the charity that runs it does has to be paid for, and most of it has to be raised again every year.
A draw is a steady, honest way for supporters to help: a fixed closing date, a result anyone can check, and a prize that is genuinely won. The prize is the nice part; the work it funds is the point.
