Highest Bidder is a card game for 2-5 players. Bidding is a central mechanism as players place secret bids from their hands onto point-scoring cards. Bids are placed simultaneously at the count of three and you never know which cards, how many and in which order your opponents will play. Once bids are placed face down in front of each player, they're revealed one card at a time. Numbered "Bid Cards" add toward the value of your bid. Strategic "Effect Cards" affect your opponents. The player with the most points once all cards have been bid on, wins.
