Slime RNG Worlds
Every documented Slime RNG world in unlock order, with unlock cost, enemy HP, coin yield per kill, and coin efficiency ratios. Use this worlds map to know when to push and when to park and grind. The Stouts Studio Discord FAQ confirmed 20 areas before the MEGA UPDATE; the May 2026 MEGA UPDATE added 5 more zones (estimated 25 total). Third-party guides (TechWiser, Game8) now document 33+ zones with extended progression data. The table below lists 8 zones with full unlock cost, HP, and coin stats. Last checked 2026-05-09
Zone Progression Strategy: When to Push, When to Park
The single biggest early-game mistake is pushing to the next zone before your slimes can clear it efficiently.
Each zone increases enemy HP and coin yield. The decision to push forward depends on one question: can your DPS slimes kill enemies in the next zone fast enough to maintain or improve your coins-per-minute rate? If enemies take 3x longer to kill but only pay 2x more coins, you are losing money by pushing. The coin efficiency ratio (coins per kill ÷ enemy HP) is the key metric — it tells you the coin return per point of damage dealt.
- Push when: enemies in the next zone die in under 3 seconds, you have 2x the unlock cost saved, and your best DPS slime is at least Rare tier for the zone's HP threshold.
- Park when: enemies take 5+ seconds to kill, the next unlock cost would drain your coin balance below 50%, or you need to upgrade slimes or builds before progressing.
- Golden rule: never unlock a zone if the unlock cost is more than 50% of your current coin balance. The coin income drop from a failed zone push can set you back hours.

Using worlds for Slime RNG rebirth cost
If you searched Slime RNG rebirth cost, the core number is 10,000,000 Coins to unlock the Goop branch. This worlds page explains where those Coins come from; the full Slime RNG rebirth cost and requirements guide explains Goop costs, max rebirth, what resets, and when to rebirth.
Worlds table — unlock cost, enemy HP, and coins per kill
| # | Slime RNG world | Unlock cost (Coins) | Enemy HP | Coins / kill | Efficiency (coins/HP) | Notes |
|---|---|---|---|---|---|---|
| 1 | Meadow | Free start | 100 | 10 | 0.100 | Starter zone. Hand-walk through your first 100 enemies to learn the auto-roll loop. |
| 2 | Forest | 2,000 | 500 | 50 | 0.100 | First payoff jump. Buy Auto Roll before unlocking. |
| 3 | Cavern | 15,000 | 2,500 | 250 | 0.100 | Coin density jumps 5x. Aim for at least one Rare slime before parking here. |
| 4 | Tundra | 100,000 | 15,000 | 1,500 | 0.100 | Where most early Lucky Slime grinders settle. Stack Luck Boost codes here. |
| 5 | Storm | 750,000 | 100,000 | 10,000 | 0.100 | Big enemy HP wall - bring an Orca / Huge Spike for clear speed. |
| 6 | Void | 5,000,000 | 750,000 | 75,000 | 0.100 | First zone where rebirth-tier coin throughput becomes realistic. |
| 7 | Crystal Cave | 35,000,000 | 5,000,000 | 500,000 | 0.100 | Post-rebirth grinding zone for stockpiling Goop currency. |
| 8 | Alien Hive | 250,000,000 | 35,000,000 | 3,500,000 | 0.100 | End-game zone. Multi-rebirth runs end here. |
Source: slime-rng.wiki. Efficiency column shows coins earned per point of damage dealt — higher numbers mean more efficient farming. Note Meadow's 0.100 efficiency vs Tundra's 0.100 — Tundra maintains the ratio but with 150x the absolute coin output, making it the first major income spike.
Coin Efficiency: Where Each Zone Stands
Absolute coins matter more than efficiency ratios once your DPS slimes can clear enemies quickly.
Efficiency sweet spots
- Forest (0.100) — 5x coin jump from Meadow with only 5x HP increase. First worthwhile farming stop.
- Tundra (0.100) — maintains Forest's efficiency ratio but at 30x the absolute scale. First zone where 100K+ coins per session is realistic.
- Void (0.100) — same efficiency ratio at endgame scale. 75K coins per kill is where 10M coin rebirth grind becomes achievable in reasonable time.
Efficiency traps
- Storm (0.100 → same ratio, 6.7x HP jump) — the ratio looks fine but the raw HP wall (100K) demands strong DPS slimes. Many players get stuck here with underpowered rosters.
- Crystal Cave (0.100 → 6.7x HP jump from Void) — 5M HP enemies require endgame-tier slimes. Do not attempt without Huge-tier DPS or multi-rebirth bonuses.
- Alien Hive (0.100 → 7x HP jump) — 35M HP enemies. This is exclusively for multi-rebirth endgame accounts with maxed slime rosters.

Recommended Slimes Per Zone Tier
Having the right slime for the zone's HP threshold is the difference between farming and struggling.
| Zone tier | HP range | Minimum slime tier | Recommended slimes | Why |
|---|---|---|---|---|
| Meadow–Forest | 100–500 | Common | Fin, Spike | Fast kills, no HP wall |
| Cavern–Tundra | 2,500–15,000 | Uncommon–Rare | Orca (180 DMG), Rocky (tank) | Orca is the first reliable mid-game farmer |
| Storm–Void | 100,000–750,000 | Epic–Legendary | Void Slime (25K DMG), Geode Slime | HP wall demands endgame DPS; Void Slime breaks through |
| Crystal Cave+ | 5,000,000–35,000,000 | Mythic–Huge | Huge Spike (7.5K DMG, AoE), Huge Rocky (5K DMG, tank) | Only Huge variants with AoE/piercing can clear efficiently at this tier |

Pre-Rebirth Zone Planning
Rebirth resets zones but keeps slimes. Plan your zone re-clears to minimize downtime.
After a rebirth, your Coins and zone unlocks reset to zero. However, you keep all slimes, their levels, apples/consumables, and permanent upgrades (Luck Upgrades, Roll Speed, gamepasses). This means your post-rebirth zone clears are dramatically faster than your first playthrough — your slime roster is already endgame-tier.
- Speed clear Meadow→Tundra — your existing slime roster one-shots early zones. Re-buy zone unlocks for the +luck bonuses.
- Reach Void as fast as possible — this is where coin income becomes meaningful again for your next rebirth cycle.
- Park in Void until Goop target — grind Goop for the next rebirth tier. Each rebirth makes subsequent cycles faster due to the compounding luck multiplier.
- Push Crystal Cave+ only after stacking multiple rebirths — post-rebirth zones demand multi-rebirth luck multipliers and Huge-tier DPS to farm efficiently.

Worlds quick takeaways
Coin density spikes
The biggest Coin density spike is Cavern → Tundra (10x payout per kill). If you can reach Tundra, do not park earlier.
HP wall warnings
Storm and Void are zones where without a Huge or Mythic slime, kill speed collapses. Bring an Orca, Huge Spike, or Void Slime — see the Huge slime guide before entering.
First Slime RNG rebirth zone
Void is the first zone where 10M Coin runs become realistic. Park here for your first Slime RNG rebirth cost grind.
End-game zone
Alien Hive is the final documented zone. Multi-rebirth runs end here while farming Goop for late-tree upgrades. Cross-reference the enemy database for HP-vs-coin payoffs by zone.
Push, park, or verify
Use this worlds table as a decision page, not just a list. A world is worth pushing when the coin yield increase is larger than the time lost to higher enemy HP. A world is worth parking when it gives stable coins, supports the next unlock, or helps prepare for the first rebirth threshold.

Crafting Ingredient Drop Locations by Zone
Crafting ingredients are not purchased — they drop from chests in specific zones. Knowing which zone to farm for which recipe saves time.
| Target slime | Rarity | Ingredient farming zone | Drop source | Farming tip |
|---|---|---|---|---|
| Crafty Slime | Epic | Cavern (Zone 3) | Zone chests, enemy drops | Park Auto Roll in Cavern with a Rare DPS slime; collect chests as they appear |
| Thorn Slime | Epic | Forest / Jungle tier zones | Mid-zone chest drops | Requires slightly higher DPS than Crafty; target this after Zone 3 is cleared easily |
| Geode Slime | Legendary | Mushroom Forest (extended zone list) | High-tier chest drops | High-value recipe; ingredient farming requires late-game DPS. Worth the investment — Legendary without roll RNG |

AFK Farming vs Active Grinding: Which Strategy Fits Your Session
Both approaches are valid — the right choice depends on your session length, slime roster, and current goal.
AFK Farming
Best for: Coin accumulation for the next rebirth cycle, passively filling Standard Index slots while away.
- Optimal AFK zone: Tundra (Zone 4) for pre-rebirth players; Void (Zone 6) for post-rebirth accounts
- Setup: Max Roll Speed in upgrades, equip highest DPS slimes, leave Auto Roll active
- Do not AFK with Luck Boost active — the 10-minute buff window is wasted if you are not making decisions during it
- Check codes before leaving — Roll Speed codes multiply AFK efficiency significantly
Active Grinding
Best for: Huge slime hunting during a Luck Boost window, zone pushing decisions, crafting ingredient runs.
- Active zone management: swap roster between luck-focused (Huge Lucky + Lucky Slime) and DPS-focused (Void Slime) as session goals shift
- Timing matters: pop Luck Boost only when roster is set, Huge Lucky is slotted, and a friend is in the same server (see server luck)
- Zone pushing: push only when coin balance is above 2x the unlock cost — see push/park framework above
- Duration: 60–180 minutes is the optimal active grinding window; shorter sessions are better spent on AFK setup and code redemption
