So, what rewards can you expect to indulge in when it comes to playing free online slot machines?

How Slots Evolved to Offer Freebies

Many years ago, before gambling technology advanced to such a high degree, basic lever-and-pulley slot machines could be found littering the majority of the gaming floor inside casinos, and worked with 3-reels and a few sets of paylines. These machines were capable of spitting out hundreds, if not thousands of dollars when a jackpot was hit, and often if a player was on a hot streak, they would receive incentives from casino staff such as a free drinks, a meal, or coupon in order to keep them playing.

When online slots emerged on the gambling scene some decades later, not only did they have lower denominations and could be played with much smaller wagers, developers soon began to step things up in order to entice more players. They did this by introducing special symbols which could alter the game dynamics, i.e. Wilds and Scatters, and also began adding additional reels, paylines and unique bonus rounds which allowed the player to win more than just money. This extra content could see the player unlock free spins, free games, bet multipliers and sometimes be given a choice to play for a different type of jackpot. All within the same game.

This is why in today’s era, online slots became the kings of casino games, and is also why they’re responsible for approximately 2 thirds of all online casino revenue.

How These “Free” Features Work Now

Every slot machine works in a slightly different way to another. This could be down to the number of reels, paylines, special symbols, the theme, and many other factors. But one thing they all pretty much have in common is the free stuff.

Usually these bonus rounds are triggered when the player hits a certain combination on the reels, which then unlocks either a bunch of free games or free spins. Occasionally, you can play a round of free spins or games as a bonus reward following a mini-game, or as a result of a lucrative feature. These can very often be retriggered as well, if the right combination of symbols is lined up against the paytable. These also tend to bring with them various multipliers that can increase your bet amount substantially.

Why Should You Play Free Online Slots with Free Spins?

Even if they still remain the most popular game inside brick-and-mortar establishments, players can’t expect the same benefits when playing slots online, so the answer really is in itself.

You should play free online slots with free spins because it gives you many more chances to win.

Odds of Winning Casino Slots Online

For the best odds of winning, check out our database of the best slots games to read precise info about each of them. Factors to consider when choosing a slot game include the number of reels you want, the number of paylines (the more the better!), and the volatility of a particular slot game. Volatility refers to the frequency and size of each game’s payout. A game with low volatility pays out a lower amount, but in greater frequency. A slot with high volatility pays out much larger sums, but very rarely. If you want to start out slowly at first and not risk too much money, play slots with a low to medium volatility. For high rollers who have a larger bankroll and want a higher risk (and bigger payout), choose slots with a high volatility rating. You can find the details of a slot game’s volatility in the game descriptions.

Wide Variety of Slots Themes

The other great thing about playing slots games is the themes. Check out hundreds of the latest and greatest slots games in a wide variety of themes. Choose from Wild-West-themed slots like Trigger Happy, Gold Rush, or Gunslinger. Or head south of the border for a fandango fiesta with The Mariachi 5 or luchador action with a variety of Mexican wrestling slots. Dive into a sea of adventure for an ocean of slots with underwater themes. Search for sunken treasure in Mermaid’s Pearls, or unleash your fists of fury in the Jackie Chan series of slots games.

You can choose a game with 3-reels, 5-reels, or even no reels. In the Cubee time travel adventure slot game, there are no reels, only a swirling time vortex with 8 floating symbols. For classic 3 or 5-reel slots, you can choose your bet size or even the number of paylines per bet. With some games racking up 200 or more paylines, the winning combinations are endless! There’s hundreds of games in dozens of themes to choose from at USA Online Casino, and there really is a slots game for everyone.
