Why has pachinko swept Japan? It can hardly be the excitement of gambling, since the risks and rewards are so small. During the hours spent in front of a pachinko machine, there is an almost total lack of stimulation other than the occasional rush of ball bearings. There is no thought, no movement; you have no control over the flow of balls, apart from holding a little lever which shoots them up to the top of the machine; you sit there enveloped in a cloud of heavy cigarette smoke, semi-dazed by the racket of millions of ball bearings falling through machines around you. Pachinko verges on sensory deprivation. It is the ultimate mental numbing, the final victory of the educational system." - Lost Japan, Eng. vers., 1996
Conventional wisdom nor scientific, mathematical prove of randomness in life could do nothing to deter human's curiosity for the unknown, however small the chance of a positive outcome maybe.
