In its heyday the carousel sported an operating brass ring game, in which daring riders could reach out and pull a ring out of a holder next to the carousel.
That night, with the $6 million target fast approaching and the church now empty of gadgets, the criminals are puzzled to hear the bells ring out across the grounds.
The innermost ring of peg-holes is used for the first half-hour, and each succeeding measurement was made in the next ring out, until all eight rings were used.
It also makes use of the then-traditional setup of being able to knock an opponent out of the fighting area entirely, thus resulting in a victory by ring out.
