Number generator for bingo, lotteries etc. - triggers number series by scores achieved in two bowling alleys to combine change with skill

摘要

The number of skittles knocked over in each bowling alley (2, 3) is counted and converted to digital form by digitiser circuits (4, 5). The digitiser outputs are fed to a microprocessor circuit (1). Also connected to the microprocessor are an on/off switch (6) and game start (7) and reset (8) switches. The microprocessor generates a short series of two-digit numbers, each of which has a value between 00 and 99, the start of the series being triggered by the sum of the two bowling alley scores. The numbers are displayed on a VDU (9).
