A card game for little ones. It is intended foir fans of the books because it assumes you will know all of Kleiner Eisbär's friends. 30 cards, each showing two friends. The first player lays a card from his hand. The friend on the left is sending a letter to the friend on the right. On future turns, he can add to this card, domino fashion, from the right hand side. So, if Eisbär was sending the letter to Greta, he would first have to play a card that matches Eisbär on the right side and another friend on the left. Then a card can be added to the new left sided friend and if ever Greta appears on the lerft hand side, the letter is delivered. Winner is the player who has delivered the most letters after the cards are all used.
