Slot machines worked essentially the same way from their invention at the end of the 19th century until the early 1960s. First, the player inserted a coin. That coin unlocked the handle at the side of the machine. Second, the player pulled the handle, which started the reels spinning. Third, the reels, which contained a series of symbols, stopped in sequence. (An early innovation was stopping the reels in sequence from left to right. This assured players that the wheels spun independently and heightened the suspense about the outcome.) Fourth, perforations in plates inside the spinning wheels corresponded with the symbols. When they stopped on a winning combination, the perforations lined up in a fashion that triggered a coin side paying the winning amount. #betvoyager #betcruise
The standard three-reel machine initially had 10 symbols on each reel, creating 1,000 possible combinations. (10 times 10 times 10.) Another early innovation was the 20-symbol reel. With 20 stops per reel, a three-reel machine could land on 8,000 combinations (20 times 20 times 20), offering a greater variety of winning combinations of differing payouts.
