Mother Nature has unpacked her complete colour palette in the world of birds, so that a native bird species can be found for eleven colours by name. In Avichrom, you cleverly play colourful feather cards to attract the magnificent birds. A player may play one to two feather cards per turn. Matching feather colours are placed under each other to form rows. As an alternative to playing cards, a player may also attract birds. A bird flies into the row with the most feathers of its colour. Some of the birds have effects that can be used immediately. When the "End of the Day" card is turned over, each player has one more turn with two actions. After that, the scoring will take place. Points are awarded for the number of feathers of the same colour in each row and for the birds attracted. The player with the most points wins.
