In this game, each player takes the part of an "xtreme" rock climber trying to be the first to scale Rock Jocks Mountain. Each climber has "super-strechin' arms" that hold onto the top of the cliff. Players alternate turns grabbing and playing "rock tokens" that say what to do on each turn, and place plastic animals (goats, vultures, snakes, and even the ominous Yeti) onto your opponent's arms and legs. But be careful! Your opponent just might have a reversal token, and you'll have to put the animal on your OWN climber! The more animals you hang, the more your climber's arms stretch - and when there's too much hanging off of him, he'll tumble off the mountain!
Rock Jocks is another of those surprisingly fun dexterity/action games that was intended for kids, but can be really entertaining between sessions of other, deeper games.
