The game shows prices in its own menus but publishes no reward table, so this page gives you the formula, a worked scenario, and a scenario grid you read against your own measured payout.
rounds needed = goal ÷ reward per round. ZOO or OOF 2 publishes no per-round payout, so step one is measurement: play two or three rounds of your chosen mode and note what each paid and how long it took. Divide your goal by your measured payout, round up, and add roughly a fifth more while you are still losing rounds. Everything below — the scenario grid, the pass math, the event planning — is that one line applied to goals players actually chase, with the game's officially documented facts (roles, unlockable families, server size) doing the anchoring.
Illustrative arithmetic only — the columns are example payouts, not game data. Measure one round, find its column, read your rounds.
| Goal (read the price in-game) | Goal ÷ 10 | Goal ÷ 25 | Goal ÷ 50 | Goal ÷ 100 |
|---|---|---|---|---|
| First animal or skin unlock (starter price bracket) | 30 | 12 | 6 | 3 |
| Mid-catalog unlock | 90 | 36 | 18 | 9 |
| A week of daily sessions (target balance) | 300 | 120 | 60 | 30 |
| Cosmetic bundle budget | 500 | 200 | 100 | 50 |
Example: if your measured Zookeeper round pays 50, a mid-catalog unlock (900) is 18 rounds; with a 20% loss allowance, 22 rounds. Sessions in rounds, not hours, because no official source documents round length — the main calculator shows how to convert rounds into minutes with your own timer.
What creator videos report (labeled reports, checked 2026-10-03) and how to plan for them without pretending the numbers are official.
The Part 2 report lists 5 costumes, 6 weapons, 3 hats, 3 darts, and 1 finisher in a "Prehistoric Pass". No official surface publishes the pass, its price, or its track, so the planning rule is: set your goal as the item you want, find it on the pass track in game, and apply the same goal ÷ payout formula to whatever progress currency the track shows.
The one multiplier signal that is official is the title tag: the [X2🦴] marker ran September 24-27 and disappeared with the October 1 update. When a tag is live, halve every round count in your plan; when it is not, plan at face value. Watch the updates page for the current tag state.
From the official description and dated reports, checked 2026-10-03.
Officially unlockable; creator videos name dinosaur and animal additions across the Dinosaur Update parts. No prices or rarity are published anywhere — see the roster reference.
Officially unlockable; Cyberpunk, Steampunk, and the Elemental Bundle (Earth Gorilla, Water Hippopotamus, Fire Lion, Air Meerkat) are creator-reported sets without official prices.
Officially a family, not a list. Codes are not part of the economy at the current status — no redemption path has ever been published.
No. The official description confirms unlockable animals, skins, and rewards but names no currency values, prices, or per-round payouts, and the developer publishes no patch notes (checked 2026-10-03). That is why this page teaches the formula and works scenarios in rounds, not fake exact costs.
Your next unlock on an in-game price screen — the game itself shows what things cost. Set that price as the goal, measure what one round pays, and divide. Progress goals (pass tiers, event items) work the same way with progress-per-round instead of currency-per-round.
When the official title carries a bracketed multiplier tag — like the [X2🦴] window of September 24-27 — every documented plan halves its round count for the duration. The tag was removed by the October 1 update, so at the latest check there is no active multiplier and the plain math applies.
Official text never names the currency, so pages use 'Coins' as a neutral shorthand for whatever the in-game balance screen shows you. If the game calls it something else in your UI, trust your screen — the arithmetic does not change.
No source documents timers, capture mechanics, or win conditions beyond the one-line role objectives. Official text never names the currency or any price. This site's pages use 'Coins' as shorthand for in-game currency and avoid inventing per-round values.
