Where to Play Real Money Slots Online

Whether you want to play slots online for real money or practice for free, these are our favorite sites for US players:

How to Play Online Slots


Slots are bright, flashy and fast – but that doesn’t mean they’re confusing. They’re just as simple as they are in physical casinos.

The goal is to spin the wheel until you find enough matching winning symbols on-screen.

There are differences per game variation, but your goal always remains the same: match winning symbols on screen to win jackpots.

Choose a Slot

Slots are the most popular online game, so each casino has several options. Choose a game type and a theme that interests you and start spinning.

Types of Online Slots

Whether you’re playing for real money or playing for free, there is a wide variation of games that you’ll find.

You can choose by theme (the game might be based off a movie, a holiday, a band, etc.), but we recommend choosing by game type. There’s a wide variety here as well, but there are three types that are the most popular in US online casinos: 5-reel slots, 3-reel slots, and progressive jackpot slots.

3-Reel Slots

3-Reel Slots

The original slot machine layout

As the name suggests, 3-Reel Slots have 3 reels (columns). Players win big by getting three identical symbols lined up on those reels.

Given the recent popularity of 5-Reel Slots, 3-Reel Slots are now slightly less common at online casinos, but definitely still have their place, especially for purists.

5-Reel Slots

5-Reel Slots

By far the most popular variant

These games – as you might expect – have 5 reels (or columns) that players can spin. 5-reel slots offer players hundreds of ways to win, literally.

5-reel slots generally come with multiple paylines (winning combinations), often more than 25. It’s with these sot games that you’ll typically see the most bonus features, like free spins, wild symbols, scatter symbols, etc. (more on bonus features later).

Progressive Jackpot Slots

Progressive Jackpot Slots

The slot type where you can win the big bucks

Another game type that’s appropriately named, progressive jackpot slots are games where the jackpot grows each time a player spins.

As each player – those playing for real money, at least – spins the reel, a small portion of his or her spin contributes to the overall jackpot. Given the popularity of progressive jackpot slots, these jackpots can grow quite large, and quite quickly.

The jackpots continue to grow until somebody wins, and then it starts all over again.

Big wins on progressive jackpot games have paid millions of dollars.

Online Slot Features

As you may have noticed, there are a variety of in-game features that you will see in nearly every slot game available online. Each symbol changes the game in a different exciting way.

Online Slots Strategy & Tips

Slots is a Game of Chance

There is no “winning strategy” – play for fun. Choose a game with a theme that interests you and just enjoy spinning the reels.

Know the Payout Percentage

All slots are tipped in the casino’s favor, but not by the same amount. Our slot reviews all include the Payout Percentage – the higher the better.
