Rip packs.
Pull real graded slabs.
Opening a pack is the best 10 seconds in collecting. Everything after it is worse — waiting on grading, dealing with shipping, arguing over prices. Ripr keeps the 10 seconds and cuts the rest.
Ten seconds.
Then a receipt.
Tap the pack. The roll is derived from a seed that was committed before you touched it, and the result comes with everything you need to re-run it yourself.

Odds for this pack
Every wrapper on Ripr prints the same table. Nothing is weighted behind the scenes — the roll lands in one of these bands and that is the pull.
Most pack sites ask you
to trust them.
We'd rather you check.
Before you open anything, Ripr locks the odds and a secret seed, and shows you the seed's fingerprint. After the pull, the seed is revealed. Re-run it and you land on the same result — right here, in your own browser.
Commit
A server seed is generated and hashed with SHA-256. You see the hash before the rip, so it cannot be swapped afterwards.
Your input
Your client seed and a nonce go into the roll. Change either one and the outcome changes with it.
Reveal
After the pull the seed is published. Hash it yourself and it has to match the fingerprint you were shown.
Re-run
Same seed, same client seed, same nonce, same slab. Every time. If a result can't be checked, we don't count it.

What the check proves
The maths is plain SHA-256. The page does it with the browser's own crypto, which is the same thing you would use to audit us.
Fourteen packs.
No hidden tiers.
From pocket packs to the top shelf. Every wrapper shows its odds and every slab it can pull — tap one to load its odds into the rip above.
A slab shouldn't be
a dead end.
Collectors already value slabs, not raw cards. A graded 10 has a known grade, a known population and a market price — so once it is yours, there are six things you can do with it.
Five modes: Classic, Crazy, Terminal, Team 2v2 and Shared. Put the slab up and rip against someone.
Stake what you pulled against a bigger slab. The odds are printed before you stake it.
Throw it in the pot with everyone else. One slab leaves with the lot.
One on one, one flip, one winner. The simplest thing on the site.
Five slabs in, one bigger slab out. Clear the shelf of the ones you were never going to keep.
List it, sell it, or buy the one you keep missing. Prices in the open.
