How does the greed donation machine work?

• The machine can be jammed, like the Donation Machine, when adding coins. 
• Each character’s overall donation status is tracked separately across all playthroughs, so each character has a separate jam chance. 
  • The jam chance maxes out at 20% at 200 coins total in Greed mode, and 1% at 55 coins total in Greedier mode. 
  • The jam chance updates in real time, so even with a character that has never donated to the donation machine prior, the machine will most likely eventually jam given enough donations. 
  • The amount of coins added will persist across both Greed and Greedier runs.
• Like the Donation Machine, if a 1000th coin is donated, the Greed Donation Machine will explode, dropping several dimes. 
• You can see the detailed jam chance table at the end of the guide (note to self: add the jam chance table
