There is not one specific site to play the best free slots. In fact the whole point of demo play is to see what games are offered at different brands before ultimately deciding who you want to sign up with. Online casinos add new games, revamp old games, add and take away promotions and generally keep things fresh for players. If you’re looking for free online slots, it’s best that you explore online slot sites by various operators. When you load up free slots, the online casino will give you play credits to use. Once you’ve run out, simply exit and try another game. 

Note that the game mechanics in free online slot games are mostly identical to real money versions. The only difference is you can’t win real cash. However, they are great for learning the rules, testing the volatility or practicing with a bonus game. You can even test drive some progressive jackpot slots. Get a feel for the gameplay and rules before opening your wallet and playing for real money. Only then will you have a shot at winning an exciting progressive jackpot.

Most free slot machines provide at least one type of bonus, so the most important thing for you to do is explore various operator offers you see on this page. There is likely one that looks better to you than others, but just note that introductory promos change often and some are for a limited time. It’s important you read the terms & conditions and all requirements to redeem the best casino bonuses. Again keep in mind there are different promotions. There is free demo play where you don’t have to sign up and you can’t win real cash, and then there are actual bonuses for new sign-ups that can include a certain amount of bonus money to play with, or free credits.

Additionally, while playing you can trigger a bonus feature by landing special symbols called scatters. Some slot bonuses are activated at random during the main game. Let’s go through and explain the most popular types of bonuses.

Free spins are probably the most common type of slot bonuses and you can find them almost every online free spins casino. A free spin bonus is triggered by landing three or more Scatter symbols in any position. Some online slots let you retrigger free spins indefinitely, and even add a prize multiplier for every winning spin.

Multipliers are special symbols that can increase your prize win. Wild symbols – jokers that help complete winning combinations – often carry multipliers as an extra reward. Some online slots offer a cascading reel mechanic with added multipliers. Every time you hit a consecutive winning spin, the prize multiplier increases.

Scatter symbols are special icons that pay out whenever they land on the reels. You will receive a cash prize for each scatter. Land three or more scatters and you may trigger a bonus game.

Some developers, like BTG (Big Time Gaming), have adapted their game reels to offer many thousands of paylines. The Megaways range of online free slots can spread over 110,000 possible ways to win on a single spin.

Reel re-spins are a good way of earning free money when you play free online slot games. By hitting a certain combination, you may earn a single re-spin of the reels. You can keep triggering re-spins as long as you hit a winner.

Online slots with cluster pays differ from regular free games. When you match clusters of symbols horizontally or vertically, they will explode and disappear from the reels. The symbols sitting above will then fall into their place, possibly forming new clusters.

In the majority of free online slots, you win a prize for matching symbols on designated paylines. However, in a 243-ways-to-win slot, you win cash simply by matching symbols anywhere on adjacent reels.

1024 ways to win slots are similar to 243 ways to win free games, with more chances to bag a jackpot. To fit in 1024 win ways, these online slots usually feature 4 rows or an added reel.

Most online slots pay out when you land matching symbols from left to right. However, win both ways free slots pay out when you match symbols from right to left too.

You can play hundreds of free slot machines on your smartphone or tablet. The good news is that nowadays, the free games at mobile casinos are nearly as varied as those found at online casinos.

Mobile slots look and feel like traditional online slots. The only difference is you make decisions by swiping the reels or tapping the game buttons. Some of the layout and graphics may be different but the bonuses and payouts will be identical.

To play free casino slot games on your smartphone, you may need to download a native app from the App Store or the casino website. Some mobile casinos also let you install individual free slots directly to your device.

You can play a lot of free slot machine games through your mobile browser without downloading them. Just open the casino app from the real casino apps section and load up a game instantly.

Some US casinos let you test drive free slots just by visiting their sites. Confirm that you are over 21 and then load up a free game in your browser window. This doesn’t necessarily require registration - but you won’t be eligible to win real money either, as these are just demo games.

5-Reel Slots

The number of available paylines in a 5-reel slot can vary, but it’s common to see anything from 9-99 win lines. Some modern 5-reel slots have expandable reels that can accommodate thousands of win ways.

Progressive Slots

In a progressive slot, a portion of every qualifying bet contributes to a giant jackpot. You can trigger the jackpot by playing a special bonus game. Some progressives, however, are awarded totally at random. You can definitely try out a progressive free slot game. You won’t be able to win the jackpot, but you can get a feel for the mechanics.

Branded Slots

Video Slots

Whenever you play online free slots, the gameplay is governed by a random number generator (RNG). As soon as you tap the Spin button, the RNG calculates an algorithm which determines where the reels stop.

Every algorithm produces a number that relates to a position on every reel. The process is entirely random and there’s no way of predicting where the reels will stop. RNGs are carefully audited. Licensing bodies employ testing labs which regularly test RNGs to ensure complete fairness.

Testing bodies put RNGs through a rigorous process. They are tested over millions of spins to make sure there are no irregularities. The lab will also have pass or fail limits on which the RNG is judged.
