Gacha House Edge

11 machines on offer

The true, exit-adjusted expected value of every Collector Crypt pack — the venue behind Jupiter Gacha. Updated 2026-07-14 20:20 UTC.

Every pack you can actually buy is a losing bet.

All 11 machines advertise a positive expected value — they quote an EV above the pack price. But the only guaranteed way out is Collector Crypt's own instant buyback, which pays 85–93% of the card's value, and auto-sells your card into that offer on a Common pull. Price that exit in and the sign flips on all of them: from -5.0% (Grail Pokémon Gacha Pack) down to -9.0% (Starter Pokémon Gacha Pack). The Pokémon packs Jupiter is marketing hardest sit near the bottom of that range.

These are flagged public in Collector Crypt's API and hold real stock, but they do not appear in the pack chooser on gacha.collectorcrypt.com — and nothing in either API distinguishes them from the ones that do. We cannot confirm they are pullable, so they are not ranked above. They are listed here only because several of them price as positive-edge, which is worth knowing if you can reach them.

How the number is built

Collector Crypt publishes an ev for each machine: the rarity-weighted expected insured value of the card you pull, comped from ALT and eBay sales. They also publish instantBuyback — the share of that insured value they will pay to take the card straight back off you. So the expected cash you clear per pull, and the edge against the pack price, are:

net EV = advertised EV × buyback %
true edge = net EV ÷ pack price − 1

Nothing here is scraped or estimated — every input is a number Collector Crypt publishes. They simply never multiply the two together.
