First 30 minutes
Redeem every active code (UPDATE2, BOOM, MERGE, NUKE, FALLOUT, DETONATE), keep your first decent nuke, and let passive generation tick. Your goal is stable cash flow, not perfect rarity.
Choose a path
Free-to-play should target Auto Merge as the very first Robux purchase. Manual drag-and-drop becomes unviable around Tier 15.
When to Lock
Lock your base any time you step away for more than 5 minutes. Free-to-play players lose quintillions of stored value to opportunistic raids.
