The game theme refers to a tale by La Fontaine: The craw and the fox. One player gets the fox, the other one the craws placing 5 of his 10 craws on the tree spaces on the first line of the board. The fox player cannot see if a craw has a cheese in its mouth or not. In his turn, the craw player has 5 action points. He may use for each craw at most 1 point. There are 3 possible actions: entering new craws at the base line, advance a craw to a tree of the next line, eating a cheese for as many victory points as the number of the line. This craw is out of the game now. The fox player may move his fox one space within the fox net. All these spaces are connected with 1 to 4 trees. He may ask a craw on a connected tree to sing. If the craw has a cheese, it is out of the game, if not, it will continue. After all craws are out of the game, the roles change. The player with the most points wins.
