Vivaldi is a restoration of the traditional Italian game "Briscola Chiamata", or five-men briscola. It is a trick-taking game, starting with an auction that decides the strong set of each match. The winner of the auction will play allied with a hidden friend against the other three players. Vivaldi takes the old ruleset and adapts it into a good-looking new set of cards. It also converts into a more intuitive points system that also deepens the math and strategy.
