There are 16 nests (4x4) with pictures of birds (four kinds, four colors). A player places a ball in a nest and a cardboard egg next to it. The next player does the same, but he or she has to place the ball in a nest with a bird of either the same kind or the same color. When a player can fill the fourth nest of a diagonal or orthogonal row, he or she gets all the eggs placed so far and a new round is started. The player who collects most eggs, wins.
