After a floor loads, there is a 95% chance that a ladder will attempt to spawn. A tile is chosen at random, and if it is unobstructed then a ladder is placed. A ladder placed in this way will prevent additional ladders spawning from rocks.
Some floors are preloaded with a ladder (12, 52, 92, treasure rooms in [[Skull Cavern]]). These ladders do not prevent ladders spawning from rocks.

Every monster killed has a 15% chance of spawning a ladder, assuming the enemy was killed over an unobstructed tile. This does not prevent ladders spawning from rocks.
Every rock destroyed has a chance to spawn a ladder, becoming more likely as there are less rocks remaining. If this is successful, a ladder will spawn and prevent further ladders spawning from rocks (however, in the Skull Cavern, there is a 20% chance that a shaft will spawn instead of a ladder, and this does not prevent further ladders/shafts spawning from rocks).
Every rock hit has a base chance of 2% to spawn a ladder. This is adjusted by daily [[Luck]], increasing by 2% at best or decreasing by 2% at worst with the [[Special Charm]] adding 0.5%. Food buffs add 1% for every point of Luck. The inverse of the number of rocks remaining after the rock is hit is added (''e.g.,'' if 5 rocks remaining then 1/5 = 0.2 or 20%, if 100 rocks remaining then 1/100 = 0.01 or 1%). If no enemies remain then 4% is added. If this chance hits, then a ladder will spawn, and prevent further ladders spawning from rocks.

Specifically: Every rock destroyed has a base chance of 2% to spawn a ladder. This is adjusted by [[Luck#Daily Luck|Daily luck]], additively increasing by around 2% at best or decreasing by 2% at worst. It is also adjusted by [[Luck#Luck Buffs|Luck Buffs]], for example food buffs add 1% for every point of Luck. A player with max daily luck and +2 luck buff would therefore have a 2+2+1 = 5% base chance to spawn a ladder for each rock destroyed. The inverse of the number of rocks remaining (after subtracting the rock that was just destroyed) is added on top of that (''e.g.,'' if 5 rocks remaining then 1/5 = 0.2 or 20%, if 100 rocks remaining then 1/100 = 0.01 or 1%). If no enemies remain then another 4% is added.
