A child's version of the game Category 5 (6 nimmt!)
Players are moving animals into the 4 stables. Play proceeds clockwise round the table. A player turns up a card from the stack, which depicts one (or rarely, 2-3) out of 6 different animals. He adds it to a stable where the animal doesn't appear yet (if possible). When this is the 6th different animal for the stable, he collects all these animal cards as points.
Game ends when the draw stack is exhausted. The player who collected most cards wins.
There are some variants in the rule book, including one where you don't want to collect cards, like in the base game.
