Abstract
In a control system wherein a master control unit controls a plurality of game machines, the master control unit is provided with two calculators and a microprocessor. The two calculators accumultate, at different rates, values each corresponding to the number of coins inserted into each of the game machines for every game. The two different accumulated values are used alternately to set the amount of money to be paid out for a particular hit and one of the values is indicated by an indicator. For every occurrence of a hit, the microprocessor orders that coins be paid out according to the indicated value and that the indicated value is alternately changed from one of the two accumulated values to the other.
