Undercut is a game created using Icehouse Pieces. It's an auction game where the players score points based on sets of similar pieces, but the twist is that the player with the lowest score wins. During each round, players are required to bid on a set of pieces, and it is desirable to win the auction on the set of pieces which most avoids matching pieces.Game System Icehouse Pieces Design Competitions Ice Game Design Competition - Winner in 2nd Competition - BoardGameGeek
