One might consider slot machines to be America's gambling pastime. Slots have been around since the late 1800s and have seen an array of changes to their make and model in the last century-plus. What was once a simple machine with an arm crank on the right side that was used to jumpstart three rotating wheels has turned into a digital extravaganza that lights up casino floors across the world.

Now that modern technology has taken over slot machines, gamblers can 'crank that wheel' online as well. Read on to learn about the best real money casinos for online slots!

✅ How to Play Slots Online

Mostly known for their prevalence in physical casinos, slots have also been a staple in online casinos. Slots offer the most variation and simplicity for users in terms of playability, games, and prizes.

Online casinos offer hundreds of slot options, so you'll be able to try out different games as you go. The best part? Most online casinos are adding new online slot games constantly, meaning you'll never run out of new, fun options!

🧠 Understanding Online Slots

Unlike the traditional lever-pulling casino games, online casino slot games function with the push of a button (or the click of a mouse). In online casino slots, users spin the reels to win prizes by getting consecutive symbols along a pay line. 

Users can wager per spin, and their earnings depend on the value of the symbols they land and the bet size they placed. Furthermore, if the reels land on certain symbols, users might start a bonus game or feature, such as free spins.

Online casino slots differ by the value of each symbol, the number of reels, and bonus types, among other things. Some online casinos offer hundreds of different slot games to choose from on their sites, with many of the same titles available for mobile play through some of the best iPhone and Android casino apps.

Users are encouraged to read the paytable before playing an online casino slot to familiarize themselves with the payouts, symbol values, and game rules.

You may be surprised to find that some online slot games will pay significantly more than others, should you win. For more on this concept, be sure to visit our best online casino payouts page as well.
