Collection
| Stamp case | Description |
|---|---|
| Ruby  |
Contains 6 Stamps. At least one of the Stamps in the Stamp case will be new (missing from your collection). Among missing Stamps, gold ones have priority. If there are no missing gold Stamps, priority goes to sets where you're missing only one Stamp. At least one of the Stamps in the Stamp case will be Rare (3 Gems) or higher. This means the guaranteed Rare Stamp and the guaranteed missing Stamp might be the same one. |
| Golden  |
Contains 6 Stamps. At least one of the Stamps you receive from the Stamp case will be Rare (3 Gems) or higher. The chance of getting a missing (new) Stamp from the Golden Stamp case increases if you haven’t received one yet: • after 2 Stamp cases — 40% chance, • after 3 Stamp cases — 80% chance, • after 4 Stamp cases — 100% chance (guaranteed). The Stamp cases don’t need to be opened one after another — the count starts from the last time you received a missing Stamp from a Golden Stamp case. |

* Each season is divided into "Basic" and "Great” parts. The chances of obtaining Stamps depend on the season that is running.
** The probability is preliminary and changes with each Stamp obtained. The selection of a specific Stamp of a certain rarity depends on its availability in the overall Stamp pool. As Stamps are obtained, their quantity in the pool decreases, which dynamically affects the chance of getting duplicates or specific missing Stamps.
