Mystery Card Rules
Last updated September 29, 2026
Every purchase is one real, physical card from our shop. It is always delivered to you. The claw game only reveals which card it is.
1. Who can buy
You must be 18 or older and in the United States. Mystery cards are not offered in any state where they aren't allowed; if you're in one of those states the machine won't let you buy. We may ask you to confirm your age. One account per person.
2. What you buy
Each mystery card costs the price shown on the machine, plus sales tax. You can buy up to 20 at once. You can pay by card, with store credit, or both. You pay before the claw reveals your cards. The claw is an animation that shows your card: your aim, timing or skill does not change which card you get, and this is a retail purchase, not a game of skill.
3. The odds
- Every machine lists its tiers (for example Common, Rare, Chase), the value range of each tier, and the chance of each tier.
- Tap a tier to see every card in it and the exact chance of getting that card on one purchase.
- Tier odds are fixed. Inside a tier, cards with more copies in stock are more likely, so a card's chance goes up or down as other cards sell. The page refreshes these chances live and again just before you pay, and your card is picked from the stock at the moment your payment is confirmed.
- The tier odds shown are the odds used, and they never change after you pay.
- A machine only sells while every tier with a chance above zero has cards in stock. If it runs out during your order, you are charged only for the cards you received.
4. Provably fair
Before you pay, you see a fingerprint (hash) of our secret seed, and you can set your own seed. Each card is chosen from both seeds plus its own counter number (a nonce that goes up by one for every card, so each card in a 20-card order gets its own result) by a standard formula (HMAC-SHA256): first the tier by the posted odds, then the card. In your vault, tap Verify on any card to reveal our seed and check the result yourself; revealing it starts a new seed, and its new fingerprint is shown before your next purchase.
5. Your vault
Cards you get wait safely in your vault. Ask us to ship them (shipping charges apply) or pick them up free at our Fort Lauderdale shop.
6. Selling back
You can sell any card in your vault back to us for 75% of its listed value, paid as store credit right away. The listed value is the card's price in our shop at the moment you got it, shown on the card in your vault. We set shop prices from recent sales data (such as Card Ladder), updated regularly. Store credit can be used anywhere in our shop, including mystery cards, and has no cash value.
7. No cash
Mystery cards, cards received and store credit cannot be exchanged for cash.
8. Problems and refunds
If something goes wrong (a technical error, a charge without a card), text us at (205) 401-9121 or email support@collectem.us and we will fix it or refund you. We may cancel and refund purchases made through fraud or abuse.
9. No free entries or giveaways
We don't currently offer free mystery cards or giveaways. If we ever run one, it will have its own official rules, including a free way to enter. Apple and Google are not sponsors of, and are not involved in, any purchase, promotion or giveaway.
10. The rest
Our Terms of Service and Privacy Policy also apply. Pokémon and other names belong to their owners; Collect'Em Store is an independent shop.
