(for example, in the spreadsheet, stack 2 was supposed to roll over from 0 to 110 on summer 6, but since there were 4 active stacks already, it couldn't roll over and was locked at 0 (it hit 0 on summer 5)Īt the same time as this stack hit 0, another stack, stack 4, hit map 6. Sometimes this coincides perfectly with rollover (A stack hits floor 110 just as another stack hits Floor 2), sometimes you get a scenario where you have 4 active stacks still and one stack is trying to roll over but can't. Now, Stack Delay is when 4 stacks are active (Between Map 3 and 29) and another stack tries to roll over.Īt any time a Stack expires, (Hits Map 2, not Floor 2), it becomes inactive. After that, infestations can be predicted as far as you want to do the math (It get's mildly complicated because of stack delay) The only randomness is which floor you get on Day 1 of your new save game.

(Day 112 will have the same infested floors as Day 1) (*Minor variations due to stack delay) This means that after 111 days, the mine restarts its cycle since at that point each stack will have completely cycled through*. *The initial floors seem to differ between save games, which makes a predictable chart impossible, but once you know an infested floor number, you can calculate back and forth. There can only be 4 active stacks, and the Day 1 (I used warp to get to the mine on day 1 and infinite stairs to test this all out) values are Floor 11, Floor 32, Floor 55, Floor 78, Floor 99 (interesting: 21,23,23,21 between values and 23 between 99-110 to 0-11, rollover) The infestation count is divided into 5 stacks, all working independently of each other. That means out of 39 possible maps, only 19 can have the infested scenario There can be no infestations on Floors: 1-4, 19, 31-39, as well as all elevator floors There is a spreadsheet link at the end that covers year 1, spring and summer, of MY savegame* to explain this betterĮach day, the infested floors are 1 lower than the day before (Day 1, floor 11 - Day 3, Floor 9) and it rolls over from 0 to 110. Took me a while to make sense of this mathematically
