The mine is two decisions in one area: a gem production line, and an Explore Cave board that can wipe the run. Both sit behind dynamite from the beanstalk, not behind a normal plot button.
Get the dynamite
- Open the farm side until the beanstalk and its NPC, Guy, are available.
- Talk to Guy and start the race. Winning is the condition named by the official Jack? badge: "win the beanstalk race". That badge's Roblox win rate is 52.0%.
- Stay in the dialogue. In the recorded run the first result led to another race prompt instead of ending the chain.
- Repeat until dynamite can be picked up. A player comment claimed a specific race count. The recording did not verify that count. If one win does not hand you the explosive, take Guy's next prompt. Do not leave mid-dialogue.
- Carry the dynamite to the blocked mine entrance and use it on the rock barrier.
If nothing appears, confirm the place id, finish the current result screen, and look again at the same NPC. Recheck the mine only after the explosive is visibly in hand.
Inside the mine
The recorded build has pickaxe upgrades, gem rocks, mine workers, and a processing line.
- Some rocks reject the current tool while lower-tier rocks can still be mined. Upgrade the pickaxe before you decide a gem color is broken.
- Put collected gems on the mine's own path and watch them pass the processing purchases.
- Hire a mine worker only after you can point at the gathering or carry step that worker covers.
The cave board
A 23 September 2026 completion recording showed this panel wording:
Explore Cave. Dig for diamonds. 3 bombs are hidden. Cash out or risk it.
Cashing out keeps the current result. Continuing accepts the chance of a hidden bomb. The panel confirms three bombs. It does not publish odds, a reward table, or a best stopping point. There is no supported "always continue" or "always leave at $7,000" rule.
The gem line can keep running as a factory. The cave is a separate risk choice on top of it.
