Donate 439 coins to the Greed Donation Machine.
Start a Greed Mode run and defeat Ultra Greed in the final boss room on the seventh floor.
The Greed Donation Machine appears in Ultra Greed's room after every Ultra Greed fight.
Put coins into the Greed Donation Machine. Keep going over as many Greed Mode runs as it takes to reach 439 coins in total.
Donations carry over between Greed and Greedier runs. The machine can jam, and the chance goes up as your total grows. At the 1000th coin it explodes.
