Snakes and Ladders

"All games have morals; and the game of Snakes and Ladders captures, as no other activity can hope to do, the eternal truth that for every ladder you climb, a snake is waiting just around the corner; and for every snake, a ladder will compensate. But it's more than that; no mere carrot-and-stick affair; because implicit in the game is the unchanging twoness of things, the duality of up against down, good against evil; the solid rationality of ladders balances the occult sinuosities of the serpent; in the opposition of staircase and cobra we can see, metaphorically, all conceivable oppositions, Alpha against Omega, father against mother; here is the war of Mary and Musa, and the polarities of knees and nose ... but I found, very early in my life, that the game lacked one crucial dimension, that of ambiguity - because, as events are about to show, it is also possible to slither down a ladder and climb to triumph on the venom of a snake ..."

— Salmon Rushdie
