Simple ones that even Uncle Bernard can pick up after a morning on the cooking sherry include No Thanks and Skull.
More involved games that work well with lots of people include Masquarade, Sushi Go, Coup and Anomia.
Racing Demon is another old faithful that doesn’t need anything more than normal playing cards.
Camel Up, Isle of Skye, Dixit and Port Royal are some of our favourite games to play as a family.
