Collection Pieces are found by playing Bingo and daubing numbers on your cards. When a Collection silhouette appears on a card and the corresponding number is daubed, you earn progress toward that Collection Piece. Each silhouette reveals your progress (for example, 1/x), and once all required parts have been collected, the Collection Piece is completed and added to your Collection.

Not all Collection Pieces are equally common. Some pieces have a higher chance of appearing, while others are intentionally rarer and may take longer to complete. This means that as you get closer to completing a Collection, the remaining Collection Pieces are often the hardest to obtain.

Progress toward Collection Pieces is determined by weighted random selection. When a Collection silhouette awards progress, the game selects from the eligible Collection Pieces in that Collection using the configured rarity settings. Because of this, there is no guaranteed collection order, and two players may complete the same Collection in different sequences.

There are no special actions that increase the chance of receiving progress toward a specific Collection Piece. The best way to complete Collections is simply to keep playing Bingo and collecting as many silhouettes as possible.

Keep in mind that some Collections are available for a limited time only. If a Collection is active, playing more rounds gives you more opportunities to find both common and rare Collection Pieces before the Collection ends.
