1. Add the pets you give. 2. Add the pets you get. 3. Read the verdict.
Read this first: these are Rarity Index (RI) estimates, not market trade values. They come only from each pet’s official rarity and its Neon/Mega Neon fusion cost. Real trade value also depends on demand and availability, which RI does not measure — two Legendary pets can trade very differently. You can type your own value for any item. How RI is calculated.
No. It compares Rarity Index totals only. A trade can look “fair” by rarity but lose on demand. Use it as a quick sanity check, not a final answer.
Community value lists are the work of their authors and are not openly licensed, so we do not copy them. RI is calculated from public rarity data. If you trust a specific list, type its number into the value box.
If both totals are within 10% of the larger total, the trade is Fair. Otherwise the bigger side wins.
Not in RI — their effect on value is driven by demand, which RI does not measure. Adjust the value box manually if you want to include them.
