Animals & Zoo

Building your animal collection and unlocking Slowdown

Eternity Zoo Unlocked!

At 3 Eternities, the Zoo unlocks! This is a 9×9 grid of Animals that provide powerful permanent bonuses. Animals are bought with Animal Points (AP), which persist through Eternities.

Animal Points (AP)

AP can be acquired in three ways:

  • Trading Eternity Points (EP): 1 AP = 2 EP (base cost)
  • Trading Infinity Points (IP): 1 AP = 1e300 IP (base cost)
  • Trading Score: 1 AP = 1e30,000 Score (base cost)
  • Completing Eternity Challenges: +1 AP per difficulty completed

⚠️Critical: Buy AP Before Eternating!

Score and IP reset when you Eternate, but EP does not. Always buy AP with your current run's Score and IP before resetting! EP can be saved for later when you unlock Lab.

Each purchase increases the cost for that specific currency. The Zoo tab shows current costs. You can Respec Animals at any time (costs an Eternity reset) to refund all spent AP and choose different animals.

Animal Progression Path

You start at position 1;1 with Cat (your first Animal). You can only buy Animals adjacent to ones you already own. Total of 81 Animals exist, requiring 1,524 AP to buy all.

Recommended progression order:

Phase 1: Base Animals (Priority)

Path: 1;1 Cat → 1;2 Dog → 1;3 Parrot → 1;4 Hamster → 1;5 Ferret

Then: 2;5 Chinchilla → 2;4 Jerboa → 3;4 Duck

Focus on lap speed bonuses early. Getting 2;5 and 2;4 significantly boosts progression.

Phase 2: First 20 Animals

Goal: Complete the entire 1;1-5 through 4;1-5 block (20 animals total)

Suggested order:

  • • 2;1 Mouse → 2;3 Guinea Pig → 3;3 Rooster → 4;3 Sheep → 4;4 Cow
  • • 3;1 Chicken → 3;2 Pigeon → 4;2 Goat → 4;1 Pig
  • • 3;5 Goose → 4;5 Horse

These 20 animals form your permanent base. Reaching Animal Milestone #4 (10 animals) makes Promotions reset nothing, and Milestone #5 (20 animals) grants 100% IP/sec!

Phase 3: IP/EP Boosters

Path: 5;2 Frog → 6;2 Giraffe → 6;3 Lion → 5;1 Snake → 6;4 Hippo → 6;5 Rhino → 6;6 Elephant

Animals 6;2-6;9 provide excellent IP gain bonuses. Priority targets!

Phase 4: Score/Supernova Boosters

Targets: 3;6 Pheasant → work toward 1;6 Gopher (and surrounding animals)

These help with long runs to push higher Score for Supernova.

Phase 5: Fill Out the Grid

Strategy: Continue with 6;7 Anteater, then buy the cheapest available animals

After core animals, most bonuses are less impactful. Buy cheapest to reach milestones (48, 81 animals).

Slowdown Explained

Slowdown (unlocked with your first Animal) is a powerful mechanic that trades lap speed for ascensions:

  • Effect: Divides lap speed by 10, but grants +1 Ascension to all circles
  • Requirement: All circles must have Laps/s greater than 10
  • Usage: Click the Slowdown button (bottom-left of Revolution page) to add/remove slowdowns
  • Reset: Slowdown resets to 0 on Infinity (and Eternity)

⚠️Early Slowdown Caution

Initially, be careful not to add too many Slowdowns! If you Prestige or Promote while heavily slowed, your circles reset to low levels but keep the slowdown penalty, which can drastically slow progress. You can "Speedup" to remove slowdowns manually.

Auto Slowdown Settings:

  • With 4 Animals: Set Auto Slowdown to 1000 (conservative)
  • After Milestone #4 (10 Animals) + Challenge Milestone #2: Set to 10 for maximum effect! Prestige/Promotions no longer reset anything, so slowdown has no downside.

Your First 10-20 Animals

Between 3-8 Eternities, focus on building toward 10 Animals:

  1. Prioritize the 1;1-1;5 path first for lap speed bonuses
  2. Get 2;4 and 2;5 when possible (major lap speed boost)
  3. Work toward completing the first 20 animals (1;1-5 through 4;1-5)
  4. Buy AP with Score/IP before every Eternity
  5. Complete Eternity Challenge #1 difficulties 1-3 for free AP

💡Respec Strategy

You can respec animals to focus on different bonuses (IP/EP vs Score/Supernova), but it costs an Eternity reset. Most players find this too tedious and just keep the base 20 animals permanently, adding to them as needed.

After 10 Animals

Once you reach Animal Milestone #4 (Promotions reset nothing), update your automation:

Automate Promote:

#1: +1 Level, 0s

#2: +1 Level, 0s

#3: +1 Level, 0s

#4: +1 Level, 0s

Watch it cycle promotions rapidly for maximum gains!

🏁Next Goals

Work toward 20 Animals for Milestone #5 (100% IP/sec). Along the way, you'll unlock Lab (7 animals) and Eternity Challenges (8 Eternities). These systems work together to accelerate your progress dramatically!
