Among the most iconic symbols of casino gambling, the slot machine is a machine that takes cash or paper tickets with barcodes and spins reels to display symbols in different combinations. The player can then trigger a bonus game or win credits based on the symbols lined up on the paylines. Many slot games have a theme, and symbols vary according to that theme. Classic symbols include fruit, bells, and stylized lucky sevens.
The earliest slot machines were invented in the mid-19th century by Charles Fey, an American mechanic. Fey’s invention was an improvement over the previous electromechanical machines that required players to insert and remove coins manually.
