David Walliams: Ratburger's Go Fish Card Game

Go Fish, with considerably more rats involved.

Ask the other players for the cards you need, collect your sets, and try to remember who asked for what three turns ago. It's the same Go Fish that has kept children occupied for a century, here featuring the cast of David Walliams' Ratburger with Tony Ross' illustrations on every card.

Takes a minute to teach, works from about four players down to two, and quietly drills memory and turn-taking while everyone thinks they're just mucking about. Fits in a coat pocket.

Perfect for: car trips, cafe tables, siblings who need something to do, and anyone who has ever wondered what exactly went into that burger.
