Spring is coming and the little birds must build their nests. You can help them! Gather the twigs and place the floors so they can build their colonies. There are endless possibilities! Cooperative 3D construction game. Floor cards are placed on the table, and 5 floors are dealt to each player. The player on the right begins to build, who will have to build according to what the card indicates. If you will have to use short or long twig cards, if you have to balance some nest boxes or if you have to receive a message from the homing pigeon. Once that stage is resolved, you will have to roll the dice and see how many floors you have to go up or down with your little bird. So continue the other players. The game ends when the roof card is drawn or when there are no more floors left.
