The first slot machine was a simple one with a horizontal line that represented a payline. You slid a coin into a slot machine and if the symbol you inserted fell on the payline, you won a prize. As you might expect, the idea behind this machine was to make money. The prize was usually candy, and the odds of winning were not proportionate to the payout amount. Today, you can find many slot machines that use the same mathematical formula.
After World War II, slot machines were legalized in casinos in many countries. Governments became interested in the potential tax revenue. In France, slot machines were allowed in casinos in 1988. Electromechanical machines enabled new payout schemes, including multiplication of winnings by three and five coins. Video slot machines also simulate the reels on a monitor. If you have a winning combination, you get the same payout as if you had inserted one or more coins.
When playing online, you will have the opportunity to choose from many different games. While you may not find the same jackpot or big display as in land-based casinos, online slots are also more likely to have a creative bonus event. NetEnt’s Cash Noire slot, for example, offers a mystery chase through the Crime Zone, while ReelPlay’s Cosmic Convoy features outer space cluster payoffs. Slot machines that offer bonus games are not uncommon in online casinos, but many of these have restrictions that make them unavailable for new players.
