The Buckley bones is one of the best and clever designed machines ever made and is my dream machine to own (but out of my reach I fear).
My only actual experience of coin operated dice throwers was last year on a cruise to Shanghai. After I left the ship it was being leased to the Chinese Gov official travel agency for four months to do 4 day gambling cruises to Japan and back. The Casino had been changed to machines and live games to suit Chinese tastes including several live Sic-bo tables - a very compulsive "Sic-Bo" coin operated machine. This reminded me of the old arcade multi player machines of the late sixties with eight player stations round the circular machine. In the centre of the machine was a raised glass tube about 24 inches across and 48 inches high with three different coloured free running dice in it each about 5 inches square. Once your money was in, the machine gave the players time to pick from the many options the dice could fall, then it locked out any more coins and the floor of the glass tube bounced up and down causing the dice to fly up the 4 foot high tube. After about 10 sec of this the dice were allowed to settle and a reader at the top of the tube looking down on the dice read the result and paid the winners. A great machine that would have been popular in the seaside arcades of the '70s.
