Do the tools store my data?

Only in your own browser (timer history, checklists). Nothing is uploaded to a server.

Are the tools accurate after updates?

Each tool shows the date its numbers were checked; after every game update we re-check rates and prices and refresh the labels.

Do I need an account?

No — every tool runs free in your browser.

Can the odds calculator guarantee a class?

No. It computes probabilities, and nothing in the game guarantees a roll.

Quick answer

The roster at a glance

Every rate and every effect line below was read off the in-game spin panel on the checked date. Where the game does not print an effect line, the row says so instead of guessing.

All classes with single-spin rates and verified effects

Forkmaster	8%	12.5	500	Pitchfork swings collect 25% more hay and pitchfork upgrades cost 25% less. — verified
Demolitionist	12.4%	8.1	323	Not yet verified — Its effect panel was not opened in the checked session, so no effect line is quoted here.

How spins work

The spin economy

Spins are the only way to change class, and Gems are the only spin currency — so every Gem source funnels into this screen.

Each spin costs 40 Gems and rerolls your class immediately.
Rates are single-spin odds — no amount of spinning changes the next roll's chances.
No pity system is visible: a 0.02% class can take far longer than its average. The odds calculator shows both the average and the 90/95% safe numbers.
Gems come from run completions, Chapter 2 (+25 observed), codes, and daily rewards.

How we label facts

What 'verified' means here

Effect text only counts when the game itself displays it — not when a wiki or article asserts it.

Eight of ten effects — verified. The game prints an effect line on each class card; those lines are quoted in the table above.
Demolitionist and Prospector — unverified. Their cards were not opened in the checked session, so they keep an explicit unverified label instead of a guess.
Rates and effects re-verify after every update; this page carries the checked date so staleness is visible.

Reading the panel

How these numbers were checked

The spin panel was read frame by frame from a 1080p recording, so the roster, the rates, and the effect lines come from the game rather than from another site.

Checked 2026-09-14

Spin panel read from a 1080p recorded session on 2026-09-14 (the earlier 2026-09-06 table predated the Index + Pets update).

On the displayed total

The values printed on the panel add up to about 100.12%, not exactly 100%, because the game rounds each line. The odds calculator uses the printed values as-is rather than silently re-normalising them.

FAQ

Class questions

Straight answers with the evidence status attached.

What does Pack Mule do?

Carry 50% more hay in every bag — printed on the class card, making it one of the effects the game states outright.

What do the other classes do?

Eight of the ten print their effect line on the card, and those lines are quoted in the table above — Hay Merchant's +20% sell value, Forkmaster's Pitchfork bonuses, Drone Specialist's 30% faster drone, Hoover's cheaper and cooler vacuum, Ultimate Farmer and The Chosen One's stacked passives. Demolitionist and Prospector were not opened in the checked session, so their effects stay unverified rather than guessed.

Can I change classes?

Yes — every spin rerolls your class. There's no pick-your-class; it's the game's gacha.

Which is the rarest class?

The Chosen One at 0.02% — about 5,000 spins on average (~200,000 Gems) with no visible pity system. Ultimate Farmer at 0.2% is the next step down at roughly 500 spins average.

Checked, not copied

Rates were read from the in-game spin screen frame-by-frame and re-checked after updates — not scraped from another wiki.

Unknowns stay unknown

Where an effect is unverified, the table says so. Guessing effects would poison every decision you make with the data.
