feebuilder pack simulator: FAQ
Is this a real feebuilder pack simulator?+
It draws against the odds each rip site publishes for its feebuilder packs, so it shows what those odds feel like over many openings. Nothing is bought, won or owed, and no card is assigned to you.
Which sites sell feebuilder packs?+
Jupiter Gacha. Each publishes a value distribution per pack, and this simulator uses those published numbers, pack by pack.
Why do my results differ from the measured figures?+
Because published odds and real outcomes are two different things, which is why this site exists. Over a handful of openings the swing is huge; our measured figures come from thousands of real sampled pulls.
