Most pack-opening sites fill their packs with cards no one actually wants and hide the odds you’re playing against. CatchBack flips that: every pack publishes its real odds, every pull has a guaranteed buyback, and you can pick the risk level you want before you open.Documentation Index

Pick your risk level
Before you open a standard pack, choose how the odds tilt:Chill
Tighter probabilities around the expected value. Fewer extreme outcomes — more consistent pulls.
Standard
The default distribution. Balanced expected value with a real shot at upside.
Hot
Heavier weighting toward the rare end of the pool. Bigger swings — bigger upside, bigger floor risk.
Problems we don’t have
Misleading expectations
Most pack sites: Show grail cards in marketing, hide the floor odds. You don’t find out the typical pull is junk until after you spend. CatchBack: Every pack tier publishes the full probability table — every bucket, every percentage, for every risk level — before you open. No surprises.”Average pull < pack cost” economics
Most pack sites: Bake their margin into the pack so the typical pull is worth less than what you paid. That’s how they make money. CatchBack: Our packs are priced so that average pulled value ≈ pack price. Open a 50. We don’t make money on the math being against you.Disappointing floor hits
Most pack sites: Floor pulls are filler cards no one wanted. CatchBack: Floors are real cards from the published pool, with real market value. Even your worst pull is something you could actually sell.Take-it-or-leave-it buyback windows
Most pack sites: Buyback offers expire in minutes. You can’t think it over, watch the market, or hold for upside. CatchBack: Every card we sell comes with a perpetual 80% buyback guarantee. You can hold for as long as you want and cash out whenever you choose.Unverifiable randomness
Most pack sites: Black-box RNG. You can’t audit fairness. CatchBack: Every pull is seeded by your transaction ID and produced by a deterministic algorithm we publish. Same inputs always produce the same output — verifiable on every pull. See Provably Fair for the technical details.Hidden fees, paid promotion
Most pack sites: Listing fees, final value fees, promoted listings, category penalties. CatchBack: Flat $1 marketplace fee per party, no listing fees, no paid promotion. See Marketplace.Side-by-side
