Fell & Sell dungeon floors: unlock rates by depth

Five achievements mark depth, from floor 2 to floor 10, and Steam publishes what share of owners has unlocked each one. Sorted by the floor number in the condition rather than by name, they are the only measure of dungeon depth this site indexes.

Floor 2 unlocked by

82.8%

Floor 10 unlocked by

27.4%

Widest gap between rungs

floor 2 → 4

Every figure here is a Steam global achievement percentage read 2026-08-30: the share of everyone who owns the game and has ever unlocked that achievement. It is not a survey of active players, and nothing on this page was measured by us.

The depth ladder, floor by floor

The last column is a subtraction: this rung’s percentage taken from the one above it. It is not a survival rate and not a per-player statistic — just the distance between two published numbers.

The widest gap is the shallowest one: 28.0 points of owners sit between the floor 2 and floor 4 achievements. The narrowest is the deepest, floor 8 to 10, at 3.6 points. Both are differences between percentages of the same denominator; what produced them is not in this data.

Achievement names are reproduced exactly as Steam renders them, duplicates included — two of these five carry the same name, which is why the table is keyed on the floor number in the condition. The duplicate-name problem across all 97 achievements is written up on the achievements page.

The boss counter

Three achievements count boss kills cumulatively. They are a counter, not a roster: the highest asks for 3 kills, which says nothing about how many bosses the game contains.

The first boss kill sits at 43.6%, between the floor 4 figure (54.8%) and the floor 6 figure (39.4%). That is where the number falls in a sorted list and nothing more — the achievement conditions say nothing about where bosses are placed, or whether they stand between floors.

What the figures do not say

• Whether floor 10 is the bottom. The ladder stops rewarding depth there; no source this site indexes states a floor count.
• What is on any floor. Room types, enemies, traps and loot are absent from the achievement data and unmeasured here.
• Why the gaps are the size they are. Difficulty, time and simply moving on all look identical in a percentage.
• How to get deeper. This site publishes no strategy advice until it has measured data, and it has none for the dungeon.

Dungeon lines in the patch notes

Two patches carry dungeon-side entries. Both are quoted as the developer wrote them; neither describes the dungeon’s shape or its length.

• Ver. 1.1.1 - SAVE SYSTEM IMPROVEMENTS + UNSTUCK BUTTONthe announcement
  • “House Wiping Bug — targeted the critical save-file issue that cleared all furniture and items in the house when coming back from a dungeon or the forest.”
  • “Perk Persistence — perks now correctly persist when transitioning between dungeon floors.”
  • “Missing Armor — Iron Oni Mask and Iron Light Armor now drop in the dungeon and render correctly on an armor rack.”
  • “Unstuck Button — safely returns the player to the dungeon entrance if clipped out of bounds or trapped.”
  • “Return to Village — a temporary option to smoothly return to the village while the dungeon generator issue is worked on.”
• Ver. 1.1.3 - SPECIAL ROOMS FIXthe announcement
  • “Special Dungeon Rooms — fixed how special dungeon rooms are saved, ensuring they reload correctly after leaving the dungeon.”
  • “Furniture Loss Prevention — fixed the issue that caused furniture to disappear when returning from dungeons. This system acts as a safety net, primarily for players upgrading from version 1.1.0 or lower, moving any previously lost items directly into the Construction Chest.”

Quoted from the developer’s Steam announcements, last re-read 2026-08-31. Both posts are listed in full, with everything else they changed, on the updates page.

Dungeon floors, answered directly

How many floors does the Fell & Sell dungeon have?

Not stated anywhere this site indexes. The Steam achievement list stops rewarding depth at Dungeon Floor 10, and neither the achievement conditions nor the developer's Steam announcements give a floor count. A ladder that ends at 10 is not the same thing as a dungeon that ends at 10, and this page does not treat it as one.

What percentage of Fell & Sell players reach each dungeon floor?

Floor 2: 82.8%. Floor 4: 54.8%. Floor 6: 39.4%. Floor 8: 31.0%. Floor 10: 27.4%. Each figure is the share of everyone who owns the game and has ever unlocked that achievement — not a survey of active players.

Which dungeon floor has the biggest drop in the achievement figures?

The gap between floor 2 and floor 4: 28.0 points of owners separate the two achievements. The narrowest gap is floor 8 to 10 at 3.6 points. These are subtractions between two published percentages; they do not track individual players, and nothing in the data says why the figures differ.

How many bosses are in Fell & Sell?

Not published. Three achievements count boss kills cumulatively, the highest asking for 3. That is a counting threshold, not a roster, and it puts no ceiling on how many bosses exist.

Do the Fell & Sell patch notes mention the dungeon?

Yes, in two patches. Ver. 1.1.1 - SAVE SYSTEM IMPROVEMENTS + UNSTUCK BUTTON (2026-08-29) and Ver. 1.1.3 - SPECIAL ROOMS FIX (2026-08-30) each contain dungeon-side entries, quoted in full on this page. Those are the posts' own publication dates; this site last re-read the Steam news source on 2026-08-31. Neither post describes the dungeon's layout or its length.
