In Piepmatz, you cleverly play bird cards from your hand to collect seeds and birds at the bird feeder. Seeds and mated birds in your collection are worth points. Single birds score only if you have the majority of their species. On a turn, you go through these three phases in order:
Play a card — Place it face up at a perch of your choice.
Resolve effects — Compare birds on the ground with the bird at the perch. Add a bird to your collection or take a seed card. Place a bird at the feeder.
Draw new cards — Refill your hand.
The game ends when the feeder deck is empty. Play continues until each player has had an equal number of turns. Each player then selects two bird cards from their hand and discards them face down. Once all players have done this, add your remaining two bird cards to your collection and start scoring. Points are earned for seeds, mated pairs of birds, and species majorities.
