How World Portals Work
Drill Blocks for Brainrots splits underground progress into worlds — separate biomes unlocked through portal NPCs in the hub. Each world has its own block textures, brainrot spawn table, and 10-artifact set. You do not teleport to a new world until you clear the deepest floor of the previous one and interact with the portal multiple times on most builds.
This guide covers portal unlock order, costs, and drill gates. Pair it with the worlds overview and zone map.
Standard Unlock Flow
- Drill to the deepest sustainable floor in your current world.
- Break the floor block to confirm your drill meets the zone gate.
- Return to the hub and locate the world portal NPC.
- Pay any cash or crystal fee shown on screen.
- Use the portal repeatedly if the game requires multiple activations (common for world 2+).
- Collect all artifacts in the new world before rushing to the next portal.
World Progression Order (July 2026)
| World | Typical Gate | Notes |
|---|---|---|
| Surface / Starter | Automatic | Tutorial zone; Common through Epic spawns. |
| Candy World | Electric-tier drill, floor clear | First major portal hop; Rare/Legendary tables. |
| Light World | Obsidian-tier recommended | CPS-focused artifact set. |
| Void World | Mid rebirth + Frostbite class | Mythic chase during events. |
| The Moon | Late mid-game portal | Moon Shadow spawns — zone guide. |
| Deep / Primordial access | Worm feed + end drills | See Primordial zone guide. |
GoldenClover Studios supports up to 10 worlds total. Names beyond Void and Moon may arrive in future patches — check the update log after each release.
Portal Costs & Rebirth
Portal unlock fees scale with rebirth count on many builds. After rebirth, you may need to re-pay portal costs even if artifact progress persists. Budget re-unlock cash into every prestige using the rebirth calculator.
Do not portal-hop before your plot is earning enough to afford re-entry. A locked deep world with empty cash is worse than farming one world completely.
Common Mistakes
- Skipping artifact collection in world 1 — starter artifacts still boost DPS after rebirth.
- Paying for a portal with a drill that cannot break blocks inside — verify floor break speed first.
- Confusing Drill Blocks for Brainrots portals with Steal a Brainrot island springs — different games.
