The first modern slot machines were invented in the 19th century by a company called Sittman and Pitt. Their machine had five drums with 50 playing cards and you could win by lining up poker hands. However, Charles Fey managed to improve upon their design by adding a pay table and allowing you to win by lining up symbols such as spades, horseshoes, hearts, or liberty bells. He also made it possible to add a progressive multiplier that increased the amount you won if you hit certain combinations.
In addition to these features, some slots have special wild or scatter symbols that can substitute for other symbols in a pay line to generate a winning combination. In the case of scatters, a threshold number of them must be met to trigger a bonus round or free spins. Some slot games also feature random Multipliers that increase your winnings by a specific factor, such as 2X or 3X.
