Steam lists 41 achievements for Well Dweller. The checklist below keeps your own completion notes in this browser. It does not connect to Steam, award achievements or calculate the game’s own completion percentage. Story and boss objectives contain spoilers. Steam — Achievement objectives

How to use the checklist

Open the spoiler list, search by achievement name or objective, and tick the goals you have completed. Progress is saved on this browser and device when browser storage is available. Clearing site data removes it; another browser will not automatically share it. The reset action clears only this website’s checklist.

Read the objective carefully

Collection thresholds, slot thresholds, upgrades and story events are separate tasks. Completing a 10-item milestone does not establish that you have finished every related collection. Likewise, the Queen achievement’s battle objective should not be rewritten as a specific ending condition.

Missing or delayed unlock

Compare the official objective with what you actually did, then check the latest developer notes for your platform. The September 26 Steam update changed the shop achievement’s trigger. The site cannot inspect your save or promise that repeating an action will repair an unlock.
