What is "whot!"

Whot is a game played with a set of non-standard cards in five suits: circles, crosses, triangles, stars and squares. It is a shedding game similar to Crazy Eights. At one point, the game was manufactured by John Waddington Ltd.

Early packs were printed with the slogans "a unique card game" and "a game for everyone". The name of the game is given an exclamation mark ("Whot!") on later packs.
