Muzzle Run currently has three collections (Breeder Collection, Racer Collection and Rabbit Collection) and each collection contains a subset of subcollections (Common, Rare, Very Rare and Extremely Rare). Muzzle Run incentivises players who manage to own entire collections and subcollections with free tournaments awarding Matic prizes.
- You do not need to own a Racer of every generation to be considered to own an entire collection. For example, if you own an "Allan" with box preference 1 you do not need to collect any other Allans with different box preferences to complete your collection.
The user below needs to own an Andrew Racer with any shirt number (generation/box preference) to own the entire Very Rare subcollection.
