Card game for 2-4 players . There are 39 cards with animals on them numbered from 1 to 39. Each player gets 8 cards and places them facedown in front of him or her . Now one card is drawn from the facedown card pile and the first player replaces that way one of his facedown cards with that card. The goal is to get an ascending line of cards faceup but no card could be moved if once it is faceup. The replaced facedown card is now handed over faceup to the next player and so on. - BoardGameGeek
