The spider brothers Roberto and Klaus lower their sister Spinderella down the thread to the forest floor, where the ant trails run. There, the spider girl stirs up the ant marathon, with the winners determined by the players during the game. While each player tries to get their three ants to the finish line first, Spinderella intercepts the eager crawlers of her competitors from above. To do this, she must manage to get close to the little marathon runners. A mobile, hollow piece of bark that serves as a shield for the ants becomes a fiercely contested trophy among the termites. However, ants are not only safe under it but also blocked in their forward movement. In each turn, three dice and the active player decide whether to move spiders, ants, or perhaps the piece of bark. Whoever catches a foreign ant with Spinderella's help sends it back to the start and may also move one of their own ants forward. The winner is the one who gets all three of their ants to the finish line first.
