The slot machines of today with their computer controlled electronic brains and flashing lights have come a long way since Charles Frey a Germany mechanic invented the first one armed bandit in San Francisco in 1887.

The early machines were simple devices with between three and five reels each with about a dozen different symbols, a mechanical arm (hence one armed bandit) was used to crank the reels into motion and if when they stopped about 30 seconds later the symbols on the win line matched those on the payout chart a certain number of coins would be returned.

The slot machines development really took off after the Second World War with advances in technology allowing many extra features such as hold, nudge,doubling, spins, gambles and extra lines not to mention link machines sometimes accross multiple casinos allowing jackpots running into the millions of dollars. The interest in slot machines by serious gamblers rather than casual players with little to spend has resulted in the payaouts rising from about 75% twenty yeas ago to well in excess of 90% on some games now.
