Jump for Cases Animal Collection Index

A collection index in Jump for Cases is more than a shiny backpack. It is a living plan for which animals you still need, which Mutations to protect, how many plot slots you can actually field, and how to compete without freezing your money engine. This page turns index chasing into a system you can run every session.

Use it with Best Animals for keep-versus-sell calls, Animals Tier List for rarity frameworks, and Mutations for shiny-value thinking. Rebirth timing that protects your plan lives in the Rebirth Guide.

What “index” means here

Your index is the set of unique animals, variants, and Mutations you consider “caught” for long-term goals. Some players chase every species. Others chase only Legendary+ and Mutated forms. Both are valid — what matters is writing the goal down so you stop panic-selling the wrong pet after a spin binge.

Index progress should never fully override economy. Empty or weak plots slow barbells, distance, and future case quality. Collectors who go broke open fewer cases — and fall behind the index they care about.

Plot slots and the ~30 target

Community scripts and farm UIs often talk about plot capacity in the neighborhood of thirty slots as a late automation / placement horizon. Exact unlock counts can change with Lucky Animals! patches, so treat “~30” as a planning ceiling, not a hard promise.

What that number implies for collectors:

• Early game: fill every unlocked tile, even with Commons.
• Mid game: raise quality density — fewer trash pets, more Rare/Epic/Legendary anchors.
• Late game: aim toward a full high-value board where almost every slot earns or flexes on purpose.

If automation offers Auto Place Best, verify it matches your index rules before trusting a 30-slot sweep (Scripts). A heuristic that maximizes gold may still eject a trophy unique you wanted for completion.

Three-track collection goals

Run three tracks at once so you never feel stuck:

1. Economy track — highest earners on the majority of slots (Money Farming).
2. Index track — first copies of species / rarities you still need.
3. Mutation track — Mutated forms protected before any mass sell.

A practical split on a mature plot: most tiles on raw earners, a minority reserved for trophy uniques, and zero “I forgot why this Common is here” slots.

Mutations as index crown jewels

Mutations are the easiest pets to delete by accident and the hardest to replace on demand. Collection rules:

• Tag-check every animal before bulk sell.
• Prefer placing strong Mutated earners; bank weaker Mutated uniques in inventory if slots are tight.
• Enable Keep Mutated (or equivalent) before any Auto Sell experiment.
• After luck codes (LuckyDuck, SEASON2), sort Mutations first — see Codes.

Read Mutations Tier List when deciding whether a Mutated mid-tier beats a normal Legendary for a flex slot.

Session workflow for index players

1. Rejoin, claim gifts, redeem any new codes.
2. Note active luck timers — delay cleanup sells until after opens.
3. Jump for quality cases (How to Jump Farther).
4. Open cases and spins; flag new index hits immediately.
5. Place upgrades; sell only confirmed junk.
6. Survive Tsunami windows so a rare keep is not wasted on a tilted rage session (Tsunami Survival).
7. Log missing targets (species / mutation / Season exclusive).

Two focused sessions with a checklist beat one chaotic three-hour hoard.

Competing without burning out

Public servers show flashy plots and Season badges. Compete on leading indicators:

• Codes claimed the same day they drop
• Luck minutes actually played
• Plot slots filled with intentional pets
• Rebirths timed instead of panic-prestiging (Rebirth Guide)
• Mutation zero accidental sells this week

Flex animals follow those habits. Chasing only the rarest screenshot pet while your board is half empty is how collectors stall.

If you experiment with automation for Auto Collect, Auto Place, or Auto Open, keep it on an alt and read safety notes on Scripts. Index pets on a banned main help nobody.

Index checklist (copy into notes)

• Every unlocked plot slot filled
• Weakest earner identified for next upgrade swap
• Mutation tags reviewed before sells
• Legendary / Secret / Season exclusives placed or banked on purpose
• Duplicate Commons cleared after fillers exist
• Luck buff session sorted before mass sell
• Rebirth plan knows which keepers return quickly
• Missing index list updated after the session

When Season 2 reshapes the index

Season banners can add exclusives that out-earn older Legendaries or create new completion rows. During Season 2 (still live November 2026):

• Spend SEASON2 spins and the Legendary Case with plot space ready (Season 2 Guide).
• Recheck tier assumptions after Discord patch notes (Updates).
• Do not delete “old” Legendaries the night a new exclusive launches until you measure income.

How this page connects

• Best Animals — keep vs sell policy
• Players Hub — collection mindset overview
• Animals Tier List — S–C framework
• Mutations — mutated value
• Rebirth Guide — prestige without wrecking goals
• Money Farming — fund more rolls
• Tier List Hub — ranking entry point

Bottom line

Build your Jump for Cases collection like a portfolio: fill toward a high slot count, protect Mutations, chase index targets on a written list, and keep enough raw earners that you can still buy strength and rebirth on time. Collectors who stay solvent open more cases — and finish more of the index.
