Seven and a Half is a gambling game that is popular in Italy (as Sette e Mezzo), in Spain (as Siete y Media) in Brazil (as Sete e Meio) and probably in other places as well. In Italy it is traditionally played around Christmas.
Seven and a Half is a card game similar to blackjack.
Seven and a Half is played with a 40-card deck (card values from 1 to 7, and three face cards, with four suits). Face cards are worth half a point each, whereas cards from the ace to seven are worth their nominal value. The goal is reaching the highest possible score without exceeding 7,5.
