Slime RNG trade calculator · FAQ
Quick answers about how trade values are sourced, how the verdict bands work and when to walk away from a trade.
How does the Slime RNG trade calculator decide who's winning?
We total each side of the trade using community-verified slime values, then compare the two totals. The calculator returns one of five verdicts — Massive Win, Win, Fair, Slight Loss or Scam — based on the value gap. Anything within ~10% counts as Fair; trades where you receive 1.5× or more land on Massive Win.
Where do the slime values come from?
Every value is sourced from active Slime RNG trader communities (Discord, Roblox group polls, dedicated trading servers) and cross-checked against recent observed trades. We refresh values within 48 hours of every patch — new slime releases and code waves shift demand fast.
Why is Void Slime listed as 'Priceless / Display Only'?
Some endgame chase slimes don't have a stable community price — their trades are negotiated case-by-case based on what each party will accept. The calculator flags these separately so you don't get a false 'Fair' verdict on a trade that's actually deeply asymmetric.
Can the trade calculator handle Huge or Shiny mutations?
Yes — Huge and Huge-Shiny variants are priced separately from their base slime since they trade for 5-20× the standard value. Pick the exact mutation you're trading from the dropdown to get the right number.
Should I trust this trade calculator over my friend's word?
Treat the calculator as a sanity-check, not gospel. Values shift with the meta and trader sentiment — see the result as a baseline, then adjust for demand spikes (a Huge that just appeared in an event is worth more for the first week). When in doubt, walk away from any trade flagged Slight Loss or worse.
