I found this donation machine in a shop room in The Binding of Isaac: Rebirth. I have put 20 coins in it with no results. I tried to explode it, but it just spat some of my money back out at me! What does it do?

  • If you've put 20 coins in it you should've had two things unlock, shop leveup up and blue map appearing in the basement (at 20 and 10 coins respectively)

Donating money unlocks more (and probably better) shop items.

For example - at 10 donated coins, I unlocked a blue map.

  • There are lots of items to get out of donations, once you get to 50, isn't every 50 for a while?
