There are a total of 120 floors, or levels, in the Mines. Ore quality (type) and quantity increases as the player moves deeper into the Mines. The Mines are filled with rocks and dirt patches. Rocks can be mined with a pickaxe in order to obtain stone, ore and geodes. A hoe can be used on dirt patches to collect minerals, artifacts, ore, clay, and cave carrots.
To advance deeper in the Mines, a ladder must be revealed on each floor. The ladder will sometimes appear when rocks are broken or after an enemy is defeated (killing enemies is the stamina-free option to finding ladders). If a floor is "infested" or "overrun" by monsters, all enemies must be defeated on that floor before a ladder will appear.
If the player has reached at least level 2 in the Mining skill, floors can be skipped by using a Staircase (crafted from 99 Stone). A Staircase allows instant access to the next floor in the Mines. After every 5 floors, an elevator will be available, allowing access to that floor at any time.
Dying in the Mines causes the player to "forget" several of the most recent floors. Generally, around 5-11 floors will be lost, which means the elevator to those floors will not be accessible until progression is once again made. 10% of the player's gold will also be lost, as well as various inventory items, including weapons and tools (except for the Galaxy Sword). If tools are lost, they will be returned in the mail on the following day, though Fishing poles and weapons will not be returned. After dying in the mines, you will awaken in the mine entrance, apparently having been found by one of the villagers who live nearby.
A Minecart is located on the entry floor for quick travel to and from the mine. It is unlocked by completing the Community Center boiler room bundles or purchased from the Joja Community Development Form.
The Mines consist of 120 floors or levels. These floors are divided into three sections, 40 floors each, with their own themes; the first section has a brown earth theme, the second section has an ice theme, the third and last section has a lava and dark purple theme. The last ten floors of each section has a variation of the main theme; the first section (Floor 31-39) has a shadow theme, the second section (70-79) has a castle theme, and the third section (110-119) has a darker crimson theme.
The corresponding floors in each section have the same layout. For example, Floor 1, 41, and 81 have the same layout; as does 2, 42, and 82; or Floor 10, 50, and 90; and so on.

Every monster killed has a flat 15% chance of spawning a ladder, assuming the enemy was killed over an unobstructed tile. This does not prevent ladders spawning from rocks.
Some levels are preloaded with a ladder (12, 52, 92, treasure floors in skull caverns). These ladders do not prevent ladders spawning from rocks.
After a level loads, there is a 95% chance that a ladder will try to spawn. A tile is chosen at random, and if it is unobstructed then a ladder is placed. This will prevent ladders spawning from rocks
Every rock hit has a base chance of 2% of spawning a ladder. This is adjusted by daily luck/5 (+/-10% / 5 = +/- 2%) and food buffs (every point of buff/100 i.e. each point of food buff adds 1%). The inverse of the number of rocks remaining after the rock is hit is added (e.g 5 rocks remaining - 1/5 = 0.2 = 20%, 100 rocks remaining = 1/100 = 0.01 = 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. If you are in the skull caverns there is a 20% chance that a shaft will spawn instead, and this does not prevent further ladders/shafts spawning from rocks
Crates and Barrels
Crates and barrels in the mines drop items when destroyed at the following rates:
|Item||0-39||40-79||80+ (including Skull Cavern)|
The following are the special items that can be obtained from either crates and barrels or monsters carrying special items
|Dwarf Scroll I||0.16%|
|Lost Book/Mixed Seeds||0.16%|
|Dwarvish Helm (Floors 1-40 only)||0.1%|
|Dwarf Scroll II (Floors 1-40 only)||0.1%|
|Dwarf Gadget (Floors 41-80 only)||0.1%|
|Gold Bar (Floors 41-80 only)||0.1%|
|Dwarf Scroll IV (Floors 81-120 only)||0.2%|
|Strange Doll (yellow)||0.03%|
|Strange Doll (green)||0.03%|
|Ore (Level appropriate)||1.33%|
|Geode (Level appropriate)||0.51%|
Shown below are foods with buffs that are useful when spelunking in the mines. Note that eating a food with buffs will wipe out any active buffs and replace them with the buffs from the newly eaten food. If the newly eaten food has no buffs, the existing buffs will remain in effect.
Duration of buffs for food lowers as the day progresses. For example, if Crab Cakes are eaten early in the day their duration is 16+ minutes. If eaten at 10pm it only lasts 2-3 minutes.
If the screen becomes "misty", "glowy", or "foggy", several of the current level's flying monsters will spawn and attack. Consuming Oil of Garlic will prevent these infestation fogs.
Occasionally you will enter an infested floor filled with slimes or a mix of monsters. Unlike normal floors, there are no rocks and in slime-infested floors the walls and ground are covered in green slime rather than the normal themes. Forage-able items such as quartz or mushrooms may still be found though. To proceed from an infested floor, you must continue to fight until all monsters are killed (this includes duggies that may be hidden under dirt patches), at which point a ladder will appear either where the last monster was killed or next to the entrance (the player will be notified with a message saying, "A way down has appeared").
A Staircase can also be used to escape an infested floor.
An infested floor will always be on the same level for each day and goes up one level the next day. For example, if an infested floor is found on level 54 one day, it will be on 53 the next day, 52 the day after that, and so on. On some days, an infested floor might not be found because certain floors are excluded from being infested. These include elevator/treasure floors and the first five, last ten, and nineteenth floor of each section (refer back to the information about sections in Floors). There can be multiple infested floors at once, each are generally around twenty or more floors apart.
The Mushroom Floor
Sometimes a floor in the lower section of the mine (levels 81-119) will have greatly increased spawns of red and purple mushrooms. These floors will also notably have a variety of colored lanterns which usually includes at least one green lantern. Mushrooms will continue to respawn on that floor throughout the same game day (even if the player quits and restarts,) and so repeated trips can be made to collect a large number of mushrooms.
Because of the way the game chooses such floors, the mushroom floor will "move up" one level each day; for example, if level 94 is a mushroom floor on Spring 5, then level 93 will be a mushroom floor on Spring 6. A player could thus track the mushroom floor and only choose to exploit it when the level can be reached quickly such as when it is one floor below an elevator. Note however, that no mushrooms will spawn on an elevator level itself (floors ending in 0 or 5) or if the level is infested (see previous section.) Additionally, the mushroom floor is neither unique nor guaranteed -- there may be multiple active mushroom floors or no such floors at all on a given day, and that situation may persist for several days or weeks.
As of v1.3, mine floors sometimes reset in an unpredictable way, especially if playing in multiplayer. In singleplayer, there is a good chance that a mine floor will reset at the next 10-minute tick of the in-game clock, measured from the time the player leaves the floor. In multiplayer, a mine floor may not reset until all players leave the floor, and the clock advances 10 minutes.
The Bottom of the Mines
On floor 120 of the Mines is the Skull Key. The skull key is used to open a door in a cave in The Desert, leading to the Skull Cavern. It is also used to unlock the Junimo Kart arcade machine for play in The Stardrop Saloon.
Furthermore, reaching this floor also changes other parts of the game:
- prismatic shards and diamonds will now rarely drop from any monster
- gems and purple mushrooms may now be found when searching trash bins
- gems and purple mushrooms may now be requested in NPC quests
- some monsters will be stronger
(These changes were introduced in patch 1.3.27.)
- The axe, scythe or pickaxe can be used to kill monsters in lieu of the sword.
- Stone can be purchased from the Carpenter's Shop for 20g each during game year 1, making it possible to skip all 120 floors using Staircases for just under 250,000g (useful for unlocking all the floors in order to return later).
- If all monsters on a level are killed, the chance of finding a ladder under a broken rock is increased by 4%.
- Repeatedly clicking the journal icon until the journal is open during a death animation will cause the cutscene where a villager finds and revives you to be skipped. It also prevents the loss of items and gold, and the "forgetting" of mine levels.
Players with access to their saved game files may find the "Stardew Predictor" utility helpful for predicting which mine floors will be infested and which floors will be mushroom levels. The utility is located at https://mouseypounds.github.io/stardew-predictor/.
