I found a result that appears to be about a different game, Lumber Tycoon / Lumberjack Dynasty , not Secret Tycoon. So I can’t confidently give you the exact unlock steps for Lumberjack in Secret Tycoon from the available information.

What the result suggests

The only relevant-looking guidance I found says “Timberjack” is unlocked early by progressing through a chain of quests and speaking to specific NPCs, but that is for a different game and should not be used as a reliable guide for Secret Tycoon. Because of that mismatch, I’d rather not invent steps that might be wrong.

Best next step

If you want the correct answer, send me:

  • the platform, like Roblox or Fortnite Creative.
  • the exact game title as shown in the menu.
  • a screenshot of the Lumberjack requirement or unlock screen.

Then I can help narrow it down fast and accurately. TL;DR: I can’t verify how to get Lumberjack in Secret Tycoon from the available source, and the result I found seems to be for a different game.
