A variation on either Baseball or Blind Baseball. The exception is in this game, a four gets you an extra card but costs nothing, a nine is wild but costs nothing, and a three is wild but the player who receives it (at all in Blind Baseball, or dealt face-up in Baseball) must match the pot for it to be counted as wild. If the player is not interested in matching the pot, that player can simply fold, or put a "price" on the wild card.
Going clockwise around the table from the player, other players decide if they are willing to pay that player's price for the three in exchange for a card from their hand. The first player to decide he will pay the player for that wild card must pay the player's price to the player, as well as match the pot.
