How the Donkey Delivers Dead Bodies in Graveyard Keeper 2

1. The game compares the number of bodies in the morgue with the morgue capacity. If the morgue is full, the game skips the roll. Your drop chance increases by 5.
2. If the morgue has space, the game rolls a random number against your current drop chance.
3. If the random roll is lower than your current drop chance, the donkey delivers a body. Your drop chance decreases by 15.
4. If the roll fails, no body comes. Your drop chance increases by 50.

Your drop chance starts at 100. It cannot go below 0 or above 100.

The game then selects one body from your body pool.

This example shows two deliveries in a row, then one miss. The game rolls once every 2 game days. Day 0 is the first roll.

Each delivery makes the next delivery less probable. Each miss adds 50. On day 4, the roll misses. The chance goes from 70 to 100, because it cannot go above 100. Thus, the chance cannot stay low for a long time, and the deliveries come at an approximately steady rate.
