Don't trust.
Verify every pack.
Gemma is simulated pack ripping with a single rule: everything that matters — odds, outcomes, values — must be verifiable by you.
01
Real odds, on real prices
Every card in the pool carries its Cardmarket price (via LimitlessTCG), refreshed regularly. The tier odds you see at checkout are exactly the ones the draw uses — no window dressing.
02
The outcome is sealed before you pay
When you open checkout we generate a secret seed and show you its SHA-256 hash — the outcome commitment. From that moment your pack's contents can't be changed: the hash nails them down.
03
Your pick is part of the draw
You choose which pack to rip off the shelf: the result is derived deterministically from the seed plus your pick. After the reveal you get the raw seed — recompute the hash and confirm it matches the commitment shown before payment.
04
Cash out or collect
Every revealed card is worth its market price in Gemma coins. Take the instant 40% buyback — right after the rip or any time later from your binder — or move it to your vault and we ship it home, insured and tracked.
