Frog Skins 2011

Frog Skins was created for a Game Design Challenge, which charged its competitors to create a game that improved humanity in 60 seconds or less. Its target: inflation. The game gives new meaning to a CCG being a license to print money, because in this CCG, the "cards" are money — various denominations of bills from $1 to $100, to be more precise.

Each player creates a deck of five bills. As in War, each player presents a bill, and the higher bill wins the round. Ties go into a tie pool. Whoever wins the most rounds wins the game and the money. The hook, and the mechanism that combats inflation is that you may choose to rip a full bill into halves, which in the game, counts as two copies of that "card", but in the real world, causes a smidgen of deflation (the rules state that you must throw away torn bills after the game).
