First select a set of 3 monkeys to curl (you can select multiple 'standard' monkeys, but only one of each of the rest). There are 5 to choose from... the more they cost, the more points (and ultimately cash) they can earn you on each shot. The object is to score points to get enough cash ($300 min) to buy 3 monkeys for each round.
