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.

What’s actually in our packs

We offer two pack families across multiple game catalogs:

Standard pack tiers

TierPriceBest for
Base Pack$1Bulk openings, casual entry
Starter Pack$8First-time pulls, getting a feel for the platform
Bronze Pack$25Reliable mid-value pulls
Silver Pack$50Step-up tier, broader card pool
Gold Pack$100Premium tier with higher ceilings
Platinum Pack$250Elite tier, balance of value and rarity
Emerald Pack$500Ultra tier, chase-grade pools

Each tier has a published bucket distribution showing the price range you can pull and the probability of each range.

You pick the game before you pick the pack.

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.
Same pack price, different odds. You see the full probability table for each risk level before you spend a cent.

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 50Silverpack,youraveragehitisaround50 Silver pack, your average hit is around 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.
