McduellMUG: You bid a number. You are trying to pick one high enough so that you are not the lowest number, but not so high you don't have enough points left at the end of the game.

McduellMUG: something that may help you in your first games would be to look at the history of some other recently finished games here http://brainking.com/en/Pond?trnst=3&trt=0 . I would pick some games that have about the same amount of players to look at and give you an idea of how the bidding usually goes.
