Stamp Collection Feature
Stamp Packs
Our Stamp Packs award between 2 to 6 stamps per pack. The exact number of stamps contained in each pack is clearly displayed on the pack itself before you open it, so there are never any surprises about quantity.
Red Pack
The Red Pack is a premium pack that contains six cards. It comes with several built-in guarantees and smart boosts to help you complete your collections faster:
- Contains exactly six cards per pack.
- At least one card is guaranteed to be either missing from your collection or to have three or more stars.
- Gold cards are prioritized among those missing cards — if you need a Gold card, the Red Pack actively works in your favor.
- If there are no missing Gold cards in your collection, you receive an 80% boost to the chance that one of the cards will be from a set where you only need one more card to complete it.
Summary of Pack Odds
- Stamp Pack: Awards 2–6 stamps (count shown on pack).
- Red Pack: Always contains 6 cards; at least 1 guaranteed missing or 3+ stars; Gold cards prioritized; 80% boost toward set-completion cards when no Gold cards are missing.
