Coin operated games machine of slot machine type

摘要

The coin operated games machine is of a `slot machine' type that has a number of illuminated symbols that are activated in a pseudo random cycle with specific symbol combinations as win combinations. This main group of symbols are associated with a further group that relate to jackpot conditions. Results from the main group periodically cause activation of one of the jackpot group and the layer can observe the progression to all jackpot symbols being illuminated and signalling a win.
