Build-A-Bucket Sandbox Mode
Sandbox is useful for exploration only when the exported run keeps its experimental context.
What was observed
Sandbox was visible as a selectable mode on Jul 25, 2026.
What has not been verified
The guide does not assume that Sandbox restrictions, player pools, or outcomes match a standard run.
What to record
Record the same visible inputs as any run and add a personal note about the experiment you were trying.
How exports label this mode
Tracker exports store the mode as Sandbox. Keep those records out of standard-run claims.
