All Worlds in Rebirth Champions Ultimate

Rebirth Champions Ultimate spreads its progression across ten themed worlds, each introducing a new egg pool, local machines, and portal requirements that must be satisfied before the next zone appears. Players who only focus on rebirth numbers without hatching the correct eggs or collecting fruits stall at portal screens despite strong stats. This page consolidates every world — Spawn, Farm, Desert, Nuclear, Atlantis, Kingdom, Cave, Volcano, Heaven, and Magic — into one reference table pulled from current community requirements. Use it alongside the world progression walkthrough for quest order and the map hub for chest and secret routes in each zone.

World Unlock Table

Requirements change when Powerful Studio patches progression. Verify portal UI in-game after major updates and check official resources for announcements. The table below reflects the standard unlock path documented across RCU guides.

Spawn World

Every account begins in Spawn World with Forest Eggs and core machines: Upgrade Machine for rebirth buttons, Index Machine for collection tracking, and Trade Portal for player swaps. Light Switch #1 hides nearby for secret room progression. Redeem codes here after tutorial completion using the code redemption guide. Spawn is not a world you unlock — it is the default hub you eventually leave for Farm.

Farm and Desert Worlds

Farm World gates behind three hundred rebirths and twenty-five Forest Egg hatches. Golden Machine, farm plots, and Farm Eggs define the zone. Our how to unlock Farm guide expands early routing. Desert World follows with rebirth performance, Farm Egg hatches, and potion usage requirements. The pyramid secret shop and Light Switch #2 make Desert the social and economic pivot of mid-game — spend Ancient Tickets via the Secret Shop guide.

Nuclear and Atlantis

Nuclear World requires fifty thousand rebirths, two hundred fifty Desert Eggs, and collected farm fruits from codes or plots. Nuclear Chest, Nuclear Pet Machine, and Light Switch #3 reward explorers. Atlantis opens through nuclear zone quests with Aura Dice mechanics and underwater-themed pets. Stock potions from the potions guide before long Nuclear hatch sessions.

Kingdom, Cave, and Volcano

Kingdom World demands five million rebirths, one Atlantean Guardian hatch, five farm fruits, and thirty Aura Dice uses. Kingdom Egg, Axe Upgrade Machine, Clan House, and Light Switch #5 anchor the zone. Cave World follows kingdom quests with Royal Ruby hatches and mining pets. Volcano escalates to one point two five billion rebirths, three hundred Cave Eggs, one Royal Ruby, and ten potion uses — Ring Machine and Magma Wood Trees define end-mid content. Collect chest loot documented on chest locations while grinding these gates.

Heaven and Magic Worlds

Heaven World represents late-game angel pets and high multipliers with requirements that shift as Powerful Studio extends the cap. Magic World ties to events and wizard pets — read the Magic event guide when seasonal content runs. Both worlds assume mastery of prestige loops from the prestige guide and optimized pet rosters from the pet tier list.

Progression Strategy by World

1. Complete every requirement category on the portal UI — rebirths alone rarely suffice.
2. Hatch the specified egg type in the previous world before brute-forcing rebirth numbers.
3. Use Fruits Chests and code fruits for Nuclear and Kingdom fruit counters per fruits and chests.
4. Explore each new world once for chests and switches before settling into egg AFK.
5. Estimate rebirth timelines with the rebirth calculator.
