Fortune Mill strategy

Upgrades & automation

There is no single purchase order for every save. This priority ladder is the safer default when two upgrades compete for the same currency.

Route recommendation · not an official tier list
  1. 01 / Unlocks
    New systems first

    A helper, mechanic, or new upgrade branch creates more options than a minor number bump.

  2. 02 / Automation
    Delete repetitive clicks

    Automation keeps one room productive while you make progress in another.

  3. 03 / Synergy
    Favor mill-wide value

    Cross-room effects can beat a locally stronger upgrade because they improve several economies.

  4. 04 / Throughput
    Fix the real bottleneck

    Upgrade supply, speed, or processing before payout when the system cannot stay active.

Completion route

51 achievements, grouped

Do not treat the Fortune Mill Steam list as one flat checklist. Finish normal progression first, then separate rare-event pulls, mode clears, and cleanup goals.

View official achievement list

After the first escape

Choose the next mode

Fortune Mill NG+ and Lethal answer different player goals. Pick the one that matches what you want to test.

01 / Progression

New Game+

Continue building at a larger scale. The official NG+ COMPLETED goal is to escape after earning $10M in every room.

Best for: deeper scaling and completion.
02 / Speed

Lethal mode

A separate speedrun challenge. Route discipline and avoiding low-impact purchases matter more than relaxed accumulation.

Best for: optimization and time pressure.
