Snakes and Ladders,

a British board-game of chance adapted from
an early Indian game, had lost its moralistic
overtones by the time I played it in the 1940s.
But in 1943 the game was introduced to the USA
from Canada with its moral tones restored -
but under the name of Chutes and Ladders,
since, it was said, children did not like the snakes,
which had originally represented sins or vices,
while ladders had represented good acts
leading up to Heaven.
