Frequently Asked Questions

The tool multiplies a pet or fruit base value by weight in kilograms, age growth (1–500), and any selected mutation multipliers to produce an estimated trade value. Every calculation runs entirely in your browser — no account, no server round-trip.

Open the Pet Value tab, select the pet rarity, enter its weight in kg and age (1–500), choose a mutation, then click Calculate Pet Value. The result panel shows value per kg, the age multiplier, the weight used, and the exact total — ready to copy.

500. The calculator rejects ages below 1 or above 500 with a clear error message. At age 500 the standard curve reaches roughly ×3 the age-1 base value.

It compares the total value you give against the total you receive and returns Win, Fair, or Lose using a ±8% fair window (ratio 0.92–1.12), along with the exact percentage gap. It is a planning aid: demand, neon/mega status, and trends can move real trades beyond raw math. Always sanity-check big deals.

Yes — multiplicatively. Golden (×20) combined with Rainbow (×100) equals ×2,000, not ×120. Use the Mutation Stack tab to combine up to three selections and see each step of the math.

Yes. The Value ↔ Weight tab converts both ways using value-per-kg for the selected pet and mutation. The conversion assumes age 1 — for age-aware values use the full Pet Value tab instead.

No. All calculations are performed client-side with vanilla JavaScript. Inputs you type are never transmitted to a server. See our Privacy Policy for full details.

No. Values are community-style estimates meant for planning and comparison. The game can change mechanics, drop rates, and pricing at any time. This site is an independent fan tool and is not affiliated with the game or its developers. Read the full disclaimer.

Switch to the Fruit Value tab. It combines crop base value, quality multiplier, weight in kg, size score (1–100, up to +50%), an optional +10% stack bonus, and fruit-specific mutations such as Wet, Frozen, Golden, or Disco.

No. Weight stays constant while age raises the value multiplier. Enter the current weight once and adjust only the age field when planning growth.

Completely free. All six modes — pet value, value↔weight, trade WFL, fruit value, age planner, and mutation stack — are available with no account, login, or paywall.

Different tools use different base tables and age/mutation curves. Ours are transparent — every result shows the multiplier breakdown so you can compare assumptions side by side. If two tools disagree, check which base values and age formulas each one uses.
