Where can you play online slots in California?
Several states permit real-money online slots, but California is not one of them. That said, if you’re looking for a legal online casino option in California, social casinos are your best bet. These platforms offer slots and other games that players in CA can enjoy using virtual currencies.
Many of these social sites feature hundreds of slots or even over a thousand, rivaling the slot libraries of regular online casinos. The games are also developed by top studios and feature the same high level of graphics, animation, and soundtracks found in the most immersive and entertaining casino slots.

Types of online slots
Classic slots
Most of the sites listed above feature a category called “classic slots,” which can be a catch-all term with various meanings. Often, the term refers to popular slots that have been around for many years, but it can also refer to traditional three-reel slots, such as those featured in retail casinos. Thus, the term might distinguish one group of slots from other, more complicated multi-reel slots with more paylines and features.
Video slots
The introduction of video slots in casinos marked a shift from mechanical reels to video screens with graphical displays. With online play, “video slots” often refers to five-reel slots but can also refer to other examples of slots with more complicated grids made possible by the freedoms of online play.
Hold and Spin slots & Hold and Win slots
Several social casinos feature hold and spin slots in which a special symbol appears and holds in place while the reels continue to spin around it. The mechanic is such that if a certain number of these symbols appear on the screen at once, that triggers a bonus game with extra free spins. Hold and win slots work similarly, triggering a bonus prize.
Jackpot slots
Just like regular online casinos, social and sweepstakes sites offer a variety of jackpot slots, including both fixed jackpot and progressive jackpot options. Fixed jackpot slots have unchanging jackpots that get awarded on a periodic basis, while progressive jackpot slots feature top prizes that continue to increase in value as long as the jackpot isn’t won.
Cascading slots & tumbling slots
Cascading slots and tumbling slots differ from regular spinning reels, offering a unique way to animate gameplay and make wins more exciting. Sometimes you’ll see the mechanic described in these games as “avalanche” in reference to the way the winning symbols explode and give way to let the higher symbols fall down into the newly empty spaces.
What you should know about online slots
Online slots players often choose games based on their themes, graphics, animation, soundtrack, and other factors that enhance their entertainment while playing. Some like to play progressive jackpot slots with the hope of winning big prizes, while others are content with non-jackpot games with fewer ups and downs.
There are even California online slot alternatives, such as Parimutuel Powered Games. Platforms like Horseplay and Giddyup offer slot-style games, but their outcomes are based on real-world horse racing results.
The more you play slots, the more you become accustomed to other relevant factors like the rate at which the game pays out, the size and frequency of the wins, game mechanics, and other elements affecting gameplay. Here are a few key factors to consider when selecting which slots to play.
Return to player (RTP) percentages
Each online slot game has a specific return-to-player (RTP) percentage programmed into its software. The games employ random number generators that guarantee a fair spin, but that also determine the average amount players will win on the game over the long term. For example, a slot with a 96% RTP will award $96 for every $100 wagered over the long term. That also indicates that the house edge is 4%, as the house receives (on average) $4 of every $100 spent on the game.
Online slots tend to feature higher RTP percentages on average than do traditional, or retail, slots. A typical selection of online slots will have a majority of slots in the 95-96% range when it comes to RTP, whereas the slot machines in retail casinos tend to skew slightly lower, in the 85-95% range. Of course, one advantage of playing slots online is the fact that you usually can look up the RTP percentage within the game, whereas in a live casino, that information can be harder to come by.
Slot volatility
Online slots also feature different levels of volatility, and you can usually look up that information as well. You’ll see a slot listed as having high, medium-high, medium, low-medium, or low volatility, or sometimes it will be described as “very high.” Volatility refers to how much winning spins tend to pay out as well as how frequently they do.
High volatility slots pay out large amounts, but the wins come less frequently than other slots. Meanwhile, low volatility slots pay out more frequently, but the wins are generally smaller. Some players like to choose slots based on their volatility, either preferring big wins less often or small wins more often.
Slot hit rate
The hit rate of a slot is related to volatility, but not quite the same thing. A slot’s hit rate simply refers to the average number of times the slot produces a winning spin. Hit rate can be expressed as a percentage (e.g., 33%) or a number indicating the average number of spins it takes for there to be a winning spin (e.g., 2.78 would mean 1 winner per 2.78 spins).
Hit rate doesn’t account for how much you win per spin, just if the spin is a winner or not. The average hit rate varies pretty widely for online slots, with most games landing in the 20-30% range but some potentially having a much lower hit rate (or higher, too).
Other online slots terms and concepts
Here are a few other terms worth knowing when playing online slots:
- free spins — extra spins won within the slot, the player can use for free and have a chance at collecting additional winnings
- multipliers — symbols that appear on the slot’s reels that can multiply your winnings
- paylines — refers to the number of ways you can win on a slot, as represented by a line of winning symbols
- pay table — a table showing all the winning combinations and their payouts for a given slot
- scatters — slot symbols that can appear anywhere on the grid (that is, not in a line but “scattered”) and still produce a payout
- wilds — wild symbols that can become any winning symbol to help fill out a payline, much like a wild card can become whatever is needed to improve a poker hand
