Vollector tracks 305 tokenized collectibles gacha packs, mystery boxes and vending machines across 13 platforms, with pull prices from $0.5 to $10,000. Expected Value, buyback rates and prize odds come from each platform's own published data and refresh every few minutes. The metrics below explain every number shown on this page.
EV: Expected Value. The average worth of a single pull over the long run. EV % compares that to the pull price, so a positive number means that across many pulls you get back more than you pay. It is a long-term average, not a per-pull promise: a gacha can have a low win rate yet a high EV when a few big prizes cover the losses of all the other pulls.
GEV: Gross EV. The same return but after the platform's instant buyback rate, so it reflects what you would actually get back if you resold every pull right away.
RAE: Risk-Adjusted EV. Tells you which pack gives you the best return for the least amount of gambling: it takes the Gross EV and adjusts it for how spread out the prizes are, so a pack that leans on lucky hits scores below a steadier one with the same return, and a higher RAE is always the better pack. Read it as a score to compare and rank packs, not as a return you will get: because a bad, swingy pack gets dragged down hard, a very negative RAE just flags the worst of the worst, while the real expected loss is the EV and GEV.
WIN: Win Rate, read from the gacha's published odds. K is for keeping the card: the chance a pull is worth at least what you paid. S is for selling it back instantly: the chance the buyback cash still covers the price after the platform's cut. S is always the harder bar to clear, so it sits at or below K.
RISK: Volatility. How spread out the possible prizes are. Low means most pulls land near the average, High means a few rare hits carry most of the value.
