[header] How to play free willy at the lake [title] Choose the " willy ". [step] This is a person who is rooting for no team, but whose goal it is to make it to shore (the shore or other goal is where they become " free "). [substeps] There should only be one willy. 
But if there is an uneven number of players, a second willy could be added to change the game a bit (both willys must make it to shore for the guardians to lose). The willy starts deep enough for people to swim around him/her.
